For every pixel, the number of rainy days in a month is reported. This dataset is created by using daily rainfall data from WaPOR precipitation data.
-
Boundary of the Niger River Basin and sub-basins obtained from level 5 of HydroBASINS (Lerner and Grill, 2013).
-
Precipitation minus actual evapotranspiration (P-ET) calculated over the Niger River Basin. The P-ET is the difference between WaPOR precipitation (based on CHIRPS) and the actual evapotranspiration and interception.
-
The land use (LU) map based on Water Accounting Plus land use classification is produced based on WaPOR land cover class and protected areas from the World Database on Protected Areas. Please read the Land Cover Classification (Africa and Near East - Annual - 100m) metadata for more information on the data source.
-
Boundary of the Litani River Basin obtained from HydroBASINS (Lerner and Grill, 2013).
-
The incremental evapotranspiration is part of the actual evapotranspiration and Interception (ETIa) that is not satified from precipitation but from supply or runoff from other cells or from groundwater. It is calculated by spliting ETIa to rainfall and incremental ET using pixel based soil moisture water balance model.
-
Saturated soil water content calculated over the Niger River Basin area. The dataset is derived from the High Resolution Soil Map of Hydraulic Properties (HiHydroSoils v1.0).
-
Boundary of the Jordan River Basin obtained from HydroBASINS (Lerner and Grill, 2013).
-
The evapotranspiration from precipitation (ETRAIN) is the portion of the actual evapotranspiration and interception (ETIa) that is satified from precipitation. It is computed from precipitation, actual evapotranspiration and soil moisture and calculated by spliting ETIa to rainfall and incremental ET using pixel based Soil Moisture Water Balance Model.
-
Boundary of the Nile River Basin and sub-basins obtained from HydroBASINS (Lerner and Grill, 2013).
