Notice: Due to delays in source data from the Global Forecast System (GFS), Rainfall Estimates (RFE), and the Global Data Assimilation System (GDAS), we are experiencing delays in producing the following products: Global GFS, GFS and RFE, Africa Runoff, Africa 10-day Soil Water Index, Africa 10-day Moisture Index, and Global GDAS Potential Evapotranspiration. We will generate those products as soon as the input data becomes available. We apologize for any inconvenience.

GeoWRSI Overview

The GeoWRSI is a geo-spatial, stand-alone implementation of the Water Requirements Satisfaction Index (GeoWRSI), as it is implemented by the USGS for the FEWSNET Activity. The program runs a crop-specific water balance model for a selected region in the world, using raster data inputs. The program produces a range of outputs which can either be used qualitatively to help assess and monitor crop conditions during the crop growing season, or can be regressed with yields to produce yield estimation models and yield estimates. Other tools are available to post-process the GeoWRSI outputs so that they can be used in yield estimation models.
