PCR-GLOBWB V1 (PCRaster GLOBal Water Balance model)

PCR-GLOBWB is a large-scale hydrological model intended for global to regional studies. For each grid cell, PCR-GLOBWB uses process-based equations to compute moisture storage in three vertically stacked soil layers as well as the water exchange between the soil and the atmosphere and the underlying groundwater reservoir.

    Detailed Description

    Quoted from: http://www.globalhydrology.nl/models/pcr-globwb-1-0/ 

    PCR-GLOBWB is a large-scale hydrological model intended for global to regional studies and developed at the Department of Physical Geography, Utrecht University (Netherlands). PCR-GLOBWB provides a grid-based representation of terrestrial hydrology with a typical spatial resolution of less than 50×50 km (currently 0.5° globally) on a daily basis. Similar to other large-scale hydrological models, PCR-GLOBWB is essentially a leaky bucket type of model [1] applied on a cell-by-cell basis. For each grid cell, PCR-GLOBWB uses process-based equations to compute moisture storage in two vertically stacked soil layers as well as the water exchange between the soil and the atmosphere and the underlying groundwater reservoir. Exchange to the atmosphere comprises precipitation, evapotranspiration and snow accumulation and melt, which are all modified by the presence of the canopy and snow cover.
