AgriMet Historical Dayfile Data Access
(Hourly Interval Data Only)
NOTE: This webform retrieves ONLY
hourly weather observations (data collected at the TOP
of each hour). This eliminates all the "MISSING" 15 minute readings
that are displayed when the selected parameter is only reported on an
hourly basis. Note that there may also be 15 minute data available for
the same parameter, but this page will only display top of the hour observations.
Many values, such as air temperature and relative humidity, are instantaneous values at the time of observation. Other observations, such as solar radiation, wind run, and precipitation, are cumulative values. Wind speed and wind direction are average values for the reporting period (typically 15 minutes). The wind speed and wind direction values reported on this page are averages for the previous 15 minutes, NOT for the previous hour.
Note that this form returns 24 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.
For hourly AND 15 minute data retrieval, click on the Hourly and 15 Minute webpage.
