CLIMWAT 2.0
Description CLIMWAT 2.0 is an extensive climatic database of more than 5,000 stations worldwide which is directly linked to the irrigation model AQUACROP. The combination of both allows users to calculate crop water requirements, irrigation supply and irrigation scheduling for various crops for a range of climatological stations.
Appropriate Use CLIMWAT, in combination with AQUACROP, can be used for planning and management of irrigated and rainfed agriculture.
Scope Global, agricultural sector.
Key Output Climate data: maximum and minimum temperature, mean daily relative humidity, sunshine hours, windspeed, precipitation and calculated values for reference evapotranspiration and effective rainfall as input data for AQUACROP.
Key Input FAOClim database.
Ease of Use Easy to use. On-line help is available.
