Trend in crop water deficit of grain maize during the growing season
European data
Metadata
-
Methodology:
The crop water deficit was calculated as the difference between the total crop water requirement (in this case for grain maize) and the rainfall sum during the growing season. The growing season has been defined as the period between grain maize emergence and physiological maturity, as simulated by the WOFOST crop model. The WOFOST crop model has been used to simulate the total grain maize water requirement during the growing season for the period 1985 to 2014. Gridded JRC-MARS meteorological and crop data have been used to force the WOFOST crop model. Also the rainfall totals per growing season were calculated from the JRC-MARS gridded meteorological database.

Additional information
The resulting simulations are provided in geotiff file (trend values) and shapefile. The shapefile contains the information on the regions where the crop water requirement during the same period (1985-2014) frequently (i.e. in more than 90 % of years) exceeds the total rainfall during the growing season. The scientific publication presenting these results is in preparation.
