(6) Establishment of an agro-climatology analysis tool and knowledge base for more than 90 countries of interest to FEWS NET. (5) Creation of stand-alone tools for enhancement of gridded rainfall data and trend analyses. (4) Development of an updated Early Warning eXplorer (EWX) tool for data visualization, analysis, and sharing. (3) Production of global expedited MODIS (eMODIS) 10-day NDVI composites updated every 5 days. (2) Global actual evapotranspiration data based on application of the Simplified Surface Energy Balance (SSEB) model using 10-day MODIS Land Surface Temperature composites at 1-km resolution. Data are available as 5-day (pentadal) accumulations at 0.05 degree spatial resolution.
USGS FEWS NET SERIES
(1) A 35-year quasi-global (+/- 50 degrees latitude) time series of gridded rainfall estimates, the Climate Hazards Infrared Precipitation with Stations (CHIRPS) dataset, based on infrared satellite imagery and station observations. USGS FEWS NET, in collaboration with the University of California, Santa Barbara, has developed a number of new global applications of satellite observations, derived products, and efficient tools for visualization and analyses to address these requirements. In recent years, it has become a requirement that FEWS NET apply monitoring and modeling frameworks at global scales to assess emerging crises in regions that FEWS NET does not traditionally monitor.
The use of remote sensing and crop modeling to address food security threats in the form of drought, floods, pests, and changing climatic regimes has been a core activity in monitoring FEWS NET countries.
Geological Survey (USGS) has a long history of supporting the use of Earth observation data for food security monitoring through its role as an implementing partner of the Famine Early Warning Systems Network (FEWS NET) program.
