This is the second video on the free MODIS Evapotranspiration product, MOD16.
In this video I’m going to show you how to download 20 years of daily actual and potential Evapotranspiration rates over a catchment, using AppEEARS. Then we will process this data in Excel to calculate average monthly ET & PET rates, and see how evapotranspiration has changed over the past 20 years.
