AgriMet NewsFebruary 28, 2012: Many changes to all AgriMet sites will occur over the spring calibration season. These changes will occur as per consultation with Dr. Richard Allen at University of Idaho, Kimberly R & E Center.
The following changes will be made at each site with a list of sites and the dates the changes occurred at each site included at the end. This list will be updated as changes are made.
- The RM Young wind sensor will be slightly relocated with the height increased from 2m to 3m to reduce
the influence on wind from sensors on the station and nearby obstacles.
- All parameters will now be reported at 15 minute intervals with wind speed reported in miles per hour
and incremental solar reported in Langleys/hour.
- Both the wind run and cummulative solar rollover values will occur at 6000 for all stations. This is
a change for solar as previous rollover values varied for each site.
- Two new parameters for air temperature and relative humidity will be added (OBX,OBN,TUX,TUN) and report
the 15 minute maximum and minimum for each parameter on a 1 second sample rate. This will allow the daily
value to reflect the true maximum and minimum for the day, rather than the maximum and minimum of the average.
- Actual vapor pressure (EA) will be computed on 1 second intervals with the average 15 minute value used to calculate dew point. This is a variation from previous dew point computation and should be more accurate.
The below list includes the date these changes were implemented for each site:

January 6, 2012: The AgriMet staion in Glenns Ferry, Idaho (GFRI) was moved to accomodate a new center pivot. The new location is available on GFRI's home page.
September 30, 2011: After 14 years of serving as the AgriMet Program Manager for the Bureau of Reclamation, Peter Palmer is retiring from Federal Service. He will be replaced by Ms. Jama Hamel beginning October 1, 2011. Ms. Hamel has been the AgriMet student technician for over 4 years, and knows the program inside and out. We look forward to her program leadership and direction as the program moves forward.
September 9, 2011: A new generic email address has been created for the AgriMet program to enhance customer support. You can now send email to all members of the AgriMet program staff at AgriMet@usbr.gov. This email address can also be found on the Contact AgriMet Webpage.
September 9, 2011: A new web page has been posted to the AgriMet website to explain AgriMet Funding Sources and Sponsors. We are grateful to the numerous sponsors who help fund the AgriMet program.
June 6, 2011: Due to licensing issues, the AgriMet Google Map has been removed until further notice. The previous version of the AgriMet Network Map has been restored.
March 16, 2011: The AgriMet Network Map has been revised to include Great Plains Region AgriMet stations in central and eastern Montana. This portion of the AgriMet Network is maintained and operated by Reclamation's Great Plains Regional Office in Billings, Montana. Clicking on a map marker will take you directly to a web page specific to the selected station. At the bottom of the network map is a link to station lists for both the Pacific Northwest and the Great Plains region AgriMet network.
February 10, 2011 AgriMet has completed development and testing of the ASCE-EWRI Standardized ET Equation. This new ET equation produces two new calculations of evapotranspiration: ETrs (evapotranspiration from a tall, rough reference surface, like alfalfa), and ETos (evpotranspiration from a short, smooth crop, like clipped grass). The purpose of the standardized reference ET equation is to bring commonality to the calculation of reference ET for agricultural and landscape use. Currently AgriMet only displays ETrs and ETos as calculated by the standardized equation; crop consumptive use information continues to be computed using the 1982 Kimberly Penman equation. ETos and ETrs information can be obtained from the Historical Archive Data Access link on the Weather Data page. The implementation of the ASCE-EWRI equation in AgriMet is on a daily (not hourly) time step.
February 9, 2011: The AgriMet Network Map has been revised and replaced with a Google Map of the Pacific Northwest. Users can select either the Terrain view (default), Map view, or Satellite view (with or without labels). The map displays markers for each weather station in the network. Hovering over the marker will display the station name; clicking the marker brings up a webpage specific to that station. The zoom and pan controls allow the user to zoom in on individual weather stations to evaluate the siting characteristics of each station. The resolution of the satellite imagery for some of the locations is sufficient for the weather station tripod to actually be seen in the image. For users with slower connections, a link to the previous version of the analog map is available at the top of the new map.
January 26, 2011: The Annual Evapotranspiration Totals and Averages web page has been updated for the 2010 growing season. This table displays the total ET by crop for each weather station for the historical period of record, along with the average ET for each crop.
Spring, 2010: During the annual spring calibration and maintenance visit, each AgriMet station had a new Rotronic Hygroclip2-S3 combination relative humidity and air temperature probe installed, replacing the Vaisala model HMP-35A and HMP45D sensors previously used. These new sensors will be swapped out every 2 years with a lab calibrated replacement, providing even greater reliability and confidence in air temperature and relative humidity measurements.
November 4, 2009: The Annual Evapotranspiration Totals and Averages web page has been updated for the 2009 growing season. This table displays the total ET by crop for each weather station for the historical period of record, along with the average ET for each crop.
Summer, 2009: Several enhancements were added during the 2009 spring and summer calibration season. Soil temperature sensors were added at Corvallis, MT (COVM) (8" depth); Fallon, NV (FALN) (4 and 20" depth); and Imbler, OR (IMBO) (2,4,8, and 20" depth) as well as a leaf wetness sensor at Imbler.
In addition, the precipitation gages were upgraded from tipping buckets to all weather load cell storage gages at Cedarville, CA, (CEDC) Ontario, OR, (ONTO), and Parkdale, OR (PARO). These storage gages will improve the winter catch efficiency at these sites. For more information about these load cell gages, see the section on AgriMet Precipitation Measurements.
November 4, 2008: The Annual Evapotranspiration Totals and Averages web page has been updated for the 2008 growing season. This table displays the total ET by crop for each weather station for the historical period of record, along with the average ET for each crop.
September 12, 2008: Reclamation's AgriMet program was awarded the annual "Industrial Achievement Award" by the Pacific Northwest Section of the American Society of Agricultural and Biological Engineers (ASABE). The award was presented on September 12, at the annual ASABE conference banquet in Boise. Use of AgriMet information provides numerous benefits to agriculture in the Northwest including reducing water and pumping costs to farmers, improving crop yields, and improving efficiency of fertilizer and pesticide use. Reclamation is proud to accept this award.
Summer, 2008: The AgriMet field maintenance team had a busy spring and summer. Numerous upgrades took place at AgriMet weather stations this year, including the installation of a shielded canopy temperature sensor at Lorella, OR, an evaporation pan sensor at Twin Falls, ID, and the installation or upgrade of 25 storage precipitation gages with new load cell weighing technology. For more information about these load cell gages, see the section on AgriMet Precipitation Measurements. The following stations were upgraded from tipping bucket precip gages to load cell storage gages to improve their snowfall catch efficiency:
CHVO Christmas Valley, Oregon
DTRO Detroit, Oregon
FTHI Ft. Hall, Idaho
LAKO Lakeview, Oregon
MALI Malta, Idaho
OMAW Omak, Washington
ONTO Ontario, Oregon
RPTI Rupert, Idaho
April 22, 2008: A new AgriMet weather station was installed near Rathdrum, Idaho. The new station, called Rathdrum Prairie (RTHI), will provide evapotranspiration and climatic data to assist in management of the water resources of the region. The Rathdrum Prairie aquifer provides irrigation water for over 10,000 acres of cropland as well as drinking water for approximately 100,000 people in Kootenai County, Idaho. The Rathdrum Prairie station is supported by Kootenai County, Idaho; the City of Post Falls, Idaho; and the Idaho Department of Environmental Quality.
January 15, 2008: A detailed explanation of AgriMet's implementation of the 1982 Kimberly-Penman Evapotranspiration Model is now available on the Crop Water Use webpage.
January 9, 2008: A new weather data report is available listing the last TWO days of hourly and 15 minute weather data for an individual station. This new report is included on the Weather Data Page and is called hourlydata2.html.
January 8, 2008: Monthly Average ET values have been updated to included data from 2007. These Reference ET values (ETr) were computed by summing the average daily ETr for the month, for the period of record.
December 17, 2007: The Annual Evapotranspiration Totals and Averages web page has been updated for the 2007 growing season. This table displays the total ET by crop for each weather station for the historical period of record, along with the average ET for each crop.
November 27, 2007: A new AgriMet weather station was installed in the Chamokane basin near Springdale, Washington. The new station, called Chamokane (CHAW), will provide evapotranspiration and climatic information to assist in a hydrologic study of the basin being conducted by the United States Geological Survey (USGS).
July 17, 2007: Two new crop coefficient curves have been added to to the AgriMet website: Safflower and Spearmint. For a complete list of crop coefficients, see the AgriMet Crop Coefficients page under the Crop Water Use section of the AgriMet website.
July 9, 2007: The day_data.out file on the AgriMet anonymous FTP server is now updated every hour at 37 minutes past the hour. Previously, this file was updated every four hours, corresponding to the previous 4 hour data transmit protocol. The day_data.out file contains all the hourly and 15 minute weather data for the current day for all AgriMet weather stations. It is one large file, in SHEF format (Standard Hydrological Exchange Format). The file can be found in the day_wx_data folder of the AgriMet Anonymous FTP server: ftp://ftp.usbr.gov/pn/agrimet/day_wx_data/day_data.out
July 6, 2007: A new report has been added to the AgriMet anonymous FTP site. The report is a two day report of all hourly and 15 minute weather data, beginning the previous day and including the most current weather data. This new report is generated and posted on the ftp site every hour at 37 minutes past the hour. The report file name is (station)2day.txt, where (station) is the four letter identifier of the AgriMet station. The reports can be found in the day_wx_data folder of the AgriMet Anonymous FTP server: ftp://ftp.usbr.gov/pn/agrimet/day_wx_data/
July 5, 2007: A new solar radiation parameter - SI - has been added to all AgriMet weather stations. The SI parameter is incremental solar (langleys) for for the last reporting interval (usually an hour, though a few stations report solar on a 15 minute interval). The SI parameter corrects for the hidden rollover value when the cumulative SQ parameter counter resets.
June 6, 2007: The entire AgriMet network has been upgraded to hourly data transmissions, replacing the four hour transmission schedule. Most AgriMet stations transmit their data between 15 and 30 minutes after the top of each hour; the current weather data is posted to the website within a couple of minutes of the receipt of the transmission. For access to current weather data and timing of website updating, see Current Weather Data.
January 22, 2007: AgriMet welcomes Ms. Jama Hamel, student technician to the program. Jama will be responsible for daily quality control of AgriMet weather data, crop water use models, instrument and sensor calibration, and other duties. She can be reached at (208) 378-5203, or by email at firstname.lastname@example.org
August 7, 2006: During the spring and summer calibration and maintenance visits, many more AgriMet weather stations were upgraded from 4 hour transmissions to hourly transmissions. The current weather data for each of the hourly transmitting stations is updated on the web page once an hour shortly after the station transmits. For a complete listing of the hourly transmitting stations and the time of the webpage update, see the Current Weather Data page.

For more information, click here.
September 27, 2005: Station installation dates have been added to two of the historical weather data access pages: Historical Archive Data Access - Column Delimited and Water Year Report Format Data Access. This allows users to choose a begin date for historical data access according to the available data for each station.
June 2, 2005: A new webpage describing Agrimet Precipitation Measurements has been added to the AgriMet website. This new page is linked from the Weather Data webpage. This new page describes the type of precipitation gages used at AgriMet weather stations, how these gages operate, and how various AgriMet precipitation parameters are computed.
May 4, 2005: Soil temperatures were installed at 4" and 8" depths at the Christmas Valley AgriMet station. The sensors are installed in non-irrigated soil.
January 21, 2005: Monthly Average ET values are now available for each AgriMet station. These Reference ET values (ETr) were computed by summing the average daily ETr for the month.
January 13, 2005: Most of the "top level" pages on the AgriMet website were revised with the new "look and feel" described in the paragraph below. At the same time, there were several other changes and enhancements implemented in the website, including:
- A revision to the map page so the station name appears when you hover the cursor over a station's symbol.
- Addition of location information (latitude, longitude, and elevation) and thumbnail photograph views on each stations' individual page (see for example, the page for the Boise, Idaho AgriMet station). You can click on each of the thumbnails for a larger view.
- Addition of a current weather forecast button for each stations' individual page that takes you directly to the current National Weather Service forecast for that area.
November 5, 2004: As part of Reclamation's new Visual Identity project, the AgriMet website will be getting a new "look and feel". All Reclamation pages will share the same common layout in an effort to help web users easily navigate and find the information they need. Every effort will be made to avoid changing URLs (webpage addresses) and the AgriMet navigation bar items (previously on the top of each page) will appear on the left side. These changes will be phased in over the next couple of months, beginning with AgriMet's top level index page. For a look at the new format, click here. We welcome your comments and suggestions.
October 19, 2004: A new AgriMet Station was installed in Beatty, Oregon (BATO). This station will provide evapotranspiration and climatic information to assist in irrigation water management in the Sprague River basin (a sub basin of the Klamath River). This station is sponsored by the USDA Natural Resources Conservation Service (NRCS) and Reclamation's Klamath Basin office in Klamath Falls.
March 15-20, 2004: Most agencies in the United States Department of Interior, including the Bureau of Reclamation, were disconnected from the Internet due to court order. During that period, the AgriMet web page and anonymous FTP site were unavailable. These servers have been restored under a temporary stay of the court order. In the event that these services are disrupted again, AgriMet users should make note of the AgriMet program coordinator's phone number: (208) 378-5283. Alternate arrangements will be made to provide AgriMet information to users. For more information about the court order, visit the Department of Interior Website at www.doi.gov or the Department of Justice at www.usdoj.gov/civil/cases/cobell/appellate.htm.
January 1, 2004: The satellite transmitters supplied by Seimac, Inc. all failed on or about January 1, 2004. Seimac Engineers believe the problem may be related to the leap year algorithm in the transmitter firmware. Seimac is working to resolve the problem and will supply a fix as soon as possible. The fix will probably require a site visit to each of the affected stations, so full resolution of the problem could require a few weeks to implement. The affected stations are:
BNDW Bonneville Dam, Washington
CJDW Chief Joseph Dam, Washington
DENI Dworshak Reservoir/Dent Acres, Idaho
DTRO Detroit Lake, Oregon
GCDW Grand Coulee Dam, Washington
GOLW Goldendale, Washington
HCKO Hills Creek Lake, Oregon
KFLW Kettle Falls, Washington
LBRW Lake Bryan/Rice Bar, Washington
LKPO Lookout Point Dam, Oregon
SBMW Seven Bays Marina, Washington
SILW Silcott Island, Washington

June 4, 2003: The Dee Flat and Pine Grove, Oregon AgriMet stations were upgraded from "frost control" stations to full Evapotranspiration stations by the addition of a solar radiation sensor. Precipitation gages were also added to each of these stations. Pine Grove was relocated approximately 50 yards west of its previous location; Dee Flat was relocated approximately 1.1 miles NNE of the previous location. Crop water use information will now be available for both of these stations.
June 1, 2003: AgriMet's Irrigation Guide has been revised and updated. The irrigation guide contains information on irrigation scheduling, soil water storage capacities, root zone depths, management allowable depletions, irrigation system efficiencies, nozzle discharge vs. pressure, irrigation application computation (inches/hour), and computation of pump efficiency.
Summer, 2003: During the annual calibration and maintenance visits this year, each AgriMet weather station will have an updated datalogger program installed which adds a higher resolution average wind speed parameter. Previously, hourly average wind speed was computed from the telemetered cumulative wind run value in order to shorten the length of the transmit message. Now, average wind speed will be computed on-site every fifteen minutes, with resolution to the hundredths of a mile per hour.
May 5, 2003: The Goldendale, Washingston AgriMet station (GOLW) has been upgraded to hourly data transmission status. Weather information will be updated on the current weather data webpage every hour at 40 minutes past the hour.

February 13, 2003: The filename extensions for all references to Historical ET Summaries have been changed from ".dat" to ".txt". Some computers have a different program associated with the .dat extensions which caused problems for some users. This change should allow your browser to correctly open and display the Evapotranspiration Summaries.
February 12, 2003: The AgriMet Anonymous FTP Server has moved to meet new Department of Interior computer security requirements. The new ftp site is ftp://ftp.usbr.gov/pn/agrimet. For more information about the anonymous FTP site, see the readme file: ftp://ftp.usbr.gov/pn/agrimet/Readme/README.TXT
February 5, 2003: The wind "cap" used in the 1982 Kimberly-Penman evapotranspiration equation by the AgriMet system has been removed. Previously, this cap limited the total wind run to 150 miles per day. Based on the recommendation of the author of the 1982 Kimberly Penman procedure, this limit has been removed to allow higher ET values during windy conditions.
January 29, 2003: Definitions of crop start, cover and terminate dates used in AgriMet Crop Water Use Charts are now available on the AgriMet website.
January 22, 2003: The Historical Archive Weather Data page has been revised to a checkbox form to make multiple weather parameter selection easier.

October, 2002: New higher resolution incremental solar parameters (both global - SI and shadowband - SI2) were added to the Picabo (PICI), Parma (PMAI), and Twin Falls (TWFI) AgriMet stations. These parameters were added to the Madras (MRSO) station previously, and will be added to the Hermiston station (HRMO) in early November, 2002.
September 26, 2002: Three new AgriMet weather stations were installed at US Army Corps of Engineers (COE) reservoirs in the Willamette River basin, Oregon. These stations will collect weather data needed for water quality modeling in response to the National Marine Fisheries Service (NMFS) Biological Opinion for Columbia and Snake River operations. The three stations are: Detroit Lake (DTRO), Hills Creek Dam (HCKO), and Lookout Point Dam (LKPO).
August 21, 2002: The filename extensions for all references to Crop Water Use Charts has been changed from ".dat" to ".txt". Some computers have a different program associated with the .dat extensions which caused problems for some users. This change should allow your browser to correctly open and display the crop water use charts.
July 17, 2002: New AgriMet Station installed at Silcott Island, Washington (on the Snake River/Lower Granite Reservoir near Clarkston) (SILW). This station will collect weather data needed for water quality modeling in response to the National Marine Fisheries Service (NMFS) Biological Opinion for Columbia and Snake River operations.
May 20, 2002: The Afton, Wyoming AgriMet station (AFTY) was relocated approximately 1/4 mile to the west due to the expansion of the Lincoln County Fairground. The new location has improved exposure for wind data collection.
April 24, 2002: The Weather Data Webpage has been improved to provide easier access to the different types of AgriMet weather data available: Archive Weather Data for the last 5 days or 10 days; hourly and 15 minute (dayfiles) weather data (both current and for the last 8 days), and access to historical weather data (both archive and dayfiles). In addition, the station lists for access to these weather data files have been ordered by state.
April 20, 2002: Seven new AgriMet stations have been installed in the Snake and Columbia River basins for water quality modeling data collection. These stations were installed in response to the National Marine Fisheries Service (NMFS) Biological Opinion for Columbia and Snake River operations. The new stations are: Bonneville Dam, WA (BNDW); Chief Joseph Dam, WA (CJDW); Grand Coulee Dam, WA (GCDW); Seven Bays Marina, WA (FDR Lake) (SBMW); Kettle Falls, WA (KFLW); Lake Bryan - Rice Bar, WA (LBRW); Dworshak - Dent Acres, ID (DENI). These stations transmit on an hourly basis, and the current weather data files are updated immediately after each station transmits to improve the timeliness of current weather observations.
March 1, 2002: Internet access re-established for the Bureau of Reclamation, and the AgriMet web page is available once again!
January 17, 2002: New Hourly and 15 minute data access available on the AgriMet website for all stations for the entire period of record. Look under the "Weather Data" tab on the navigation bar. NOTE: Historical Dayfiles data access retrieves both hourly and 15 minute weather observations for the selected station, time period, and parameters, returning 96 records for each day selected. File sizes and download time vary accordingly, so please consider the potential volume of data when you choose your time period.
December 5, 2001: Internet access was disconnected for the entire Department of Interior by Federal Court order. This action removed public access to the AgriMet website as well as email into and out of Reclamation and other Department of Interior agencies. For more information, visit the Department of Interior website at www.doi.gov
