Evapotranspiration data saves water and increases crop yield
The California Irrigation Management Information System (CIMIS) provides raw weather data, as well as information on evaporation rates and crop water usage, to inform irrigation decisions. A series of surveys demonstrated CIMIS was used to save water and increase crop productivity. The benefit-to-cost ratio of CIMIS to irrigation users was between $56 and $76 for every $1 spent.
