Interactive viewers and maps provide visuals based on datasets and other geospatial modeling, along with a QGIS-based plugin developed by FEWS Net and USGS.
USGS FEWS NET Data Portal
The USGS FEWS NET Data Portal provides access to geo-spatial data, satellite image products, and derived data products in support of FEWS NET drought monitoring efforts throughout the world. This portal is provided by the USGS FEWS NET Project, part of the Early Warning Focus Area at the USGS Earth Resources Observation and Science (EROS) Center.

Water Point Viewer with CHIRPS v3
The FEWS NET Water Point viewer has been updated to use the new Climate Hazards Center Infrared Precipitation with Stations (CHIRPS v3) dataset. Additionally, the NOAA daily reference ET input data source was changed from current to 30-year climatology. A new feature includes a 30-day forecast for the water points status on the time series chart. Along with the input data changes, the site status symbolization logic was also revised for clarity and improved representation.

New snow water volume basin time series from FLDAS Snow Water Equivalent (SWE) is now available in the Middle East region of the EWX Viewers.
Learn MoreNew NDVI Products At Large Scale Available
NDVI eVMOD/eVIIRS raster data is now available as Cloud Optimized GeoTIFFs (COGs) at a continental scale for South America, extending the previous releases for Africa and Asia. These products are derived from dekadal eVIIRS data, updated every five days (pentad), and from dekadal eVMOD/eVIIRS datasets.
