The information within this README.changes document includes changes, additions, and deletions that have been made to the AWARDS/ET Toolbox processing for the Middle Rio Grande. This information has been applied to the February 18, 2004 ET Toolbox Documentation and is now included in the latest version of the documentation dated April 24, 2008 (version 2.0). DATE Activity Status of ET Toolbox Documentation ------------- ------------------------------------------------ -------------------- May 1, 2008 New Stream Flow Products figure in the documentation results in version 2.0.1. April 24, 2008 Version 2.0 of the documentation is completed except for chapter 22. December 10, 2007 Installed Toni Barrow Farm weather station in Reach 5. December 10, 2007 Removed Los Chavez Bosque weather station from Reach 5. November 13, 2007 Re-installed Prices Dairy Farm weather station October 29, 2007 Removed Prices Dairy Farm weather station from Reach 4 processing until it is repaired. October 23, 2007 Revised the web-site New Mexico home page to allow more direct access to the Awards and ET Toolbox products. October 4, 2007 Added forecast rain for forecast days 4-7. These data are Quantitative Precipitation Forecasts from the National Centers for Environmental Prediction Global Forecasting System model. The resolution of this forecasted days 4-7 rain is 1 degree by 1 degree (110km north-south by 90km east-west). June 21, 2007 Modified the New Mexico home page to allow a more direct link to the MRGCD Stream Flow Schematics. These also remain available from the New Mexico map. June 14, 2007 On June 15, 2007, the old AWARDS/ET Toolbox based on the HRAP 4x4 km grid, 3-day Eta forecast, and old URGWOM river reach delineations will be shut down. User's will automatically be redirected to the new QPESUMS (abbreviated to QPE) site that is briefly explained in the May 9, 2007 notes, below. Documentation of this new site is under way. In the meantime, information for QPESUMS can be found at: http://www.nssl.noaa.gov/projects/qpesums/ Information for seven-day weather forecasting by the National Digital Forecast Database (NDFD) models can be found at: http://www.weather.gov/ndfd/ June 13, 2007 1. Modified the AWARDS ET charts by replacing the QPF (Quantitative Precipitation Forecast) values with 3-day NDFD (National Digital Forecast Data). 2. Removed the Candelaria Farms Future 3-days Air Temperature and Relative Humidity plot since we no longer acquire hourly forecast data. May 9, 2007 Numerous changes have been made to the AWARDS/ET Toolbox. On May 8, 2007 the following were implemented: 1. Quantitative Precipitation Estimation and Segregation Using Multiple Sensors (QPESUMS) on an approximate 1-km grid. 2. Eight new URGWOM river reaches. 3. Seven-day National Digital Forecast Database (NDFD) weather forecasting models (although the rain is forecasted for only 3-days, and the solar radiation is approximated from min and max temperatures with coefficients). This forecast is on a 5-km grid. 4. URGWOM ET maps for each reach, with 1-week animation. 5. Improved ET estimates at 1-km cells that bisect reach boundaries. 6. Implemented open water evaporation estimates for the Rio Grande using the FLO2D model. 7. Estimating wet sands evaporation within the banks of the Rio Grande. 8. Estimating evaporation from Elephant Butte Reservoir 9. Estimating Tamarisk ET in the Bosque Del Apache using the Utah State Univ. model. 10. Removed cell rainfall postings. 11. Revised design of the Middle Rio Grande web site. The old HRAP 4-km, old reaches, and 3-day Eta 12-km forecast site is still available until June 15, 2007. June, 2006 Rio Chama/Velarde area window created, using an estimated crop land distribution of 30% orchard, 30% alfalfa, and 40% pasture grass. April 6, 2006 Generated historic ET summation information for each of the eight new URGWOM river reaches, based on the HRAP 4-km grid cells, for years 2000-2005. April, 2006 Implemented a new stream flow schematic for the MRGCD Belen Division May, 2005 Implemented Candelaria Farms Firld Scheduling and soil moisture measurements at many MRGCD weather stations August 4, 2004 The NMSUCC South Bosque (SBOS) hourly data is now included in the MRGCD Weather Station Network hourly pop-up image (fig. 20 in the documentation). This supports the ET Model for Tamarisk - see July 14, 2004. July 27, 2004 MRGCD weather stations are added: Name Activated ------------------------------------- --------- CQFN Cisto Quintana Farm - NM - MRGCD May 4,2004 CSBN Corrales Bosque - NM - MRGCD May 4,2004 PDFN Prices Dairy Farm - NM - MRGCD July 13,2004 BWWN Bosque Farms - NM - MRGCD May 6, 2004 LCZN Los Chavez Bosque - NM - MRGCD July 13,2004 GWFN Gus Wagner Farm - Nm - MRGCD July 13,2004 The AWARDS/ET Toolbox is rerun each day from January 1. Therefore, data from the the NCEP Eta 12 km model is used until the station is active. July 14, 2004 Added the Model for Daily Evapotranspiration of Tamarisk at the Bosque Del Apache, as detailed in a paper by Hipps and Hattori, USU. To see the results of the study, go to the inter-active AWARDS/ET Toolbox image, and click on the small white square box to the left of the Bosque window. From there, click on Tamarisk ET Model and Comparisons. June 29, 2004 Modified nexrad rainfall usage; now based on vegetative start and terminate dates rather than the entire year. June 8, 2004 Now Using the newer GIS information for land classification, a combination of the 2000 IKONOS satellite imagery at 4 meter resolution and the 2001 Utah State University (USU) aerial photography at .5 meter resolution. The IKONOS is used from Cochiti Dam to Elephant Butte Reservoir headwaters (Reaches 1-7). The USU exists in a small part of Reach 3, Reaches 4, 5, and 6, and part of Reach 7. Wherever the USU exists, the IKONOS was erased and the USU was inserted. This replaces the 1992/93 Land Use Trend Analysis (LUTA), plus others. The Toolbox was/is rerun every day from January 1, 2004 to present with these newer GIS data for all vegetation groups. The historic runs, from 1975 through 2003, continue to be based on the LUTA, plus others. June 7, 2004 Implemented the Nambe window. June 3, 2004 The Daily ET Rate Tables (fig. 18 in the documentation) now contain the GIS classification number. May 26, 2004 MRGCD weather stations are added: Name Activated ------------------------------------- --------- BBAN Bosque Bar - NM - MRGCD Mar. 2, 2004 ASFN Adolf Sanchez Farm - NM - MRGCD May 4, 2004 The AWARDS/ET Toolbox is rerun each day from January 1. Therefore, data from the the NCEP Eta 12 km model is used until the station is active.
