NOAA/National Centers for Environmental Information
NOAA's Weather and Climate Toolkit


NOAA's Weather and Climate Toolkit (WCT) is free, platform independent software distributed from NOAA's National Centers for Environmental Information (NCEI). The WCT allows the visualization and data export of weather and climate data, including Radar, Satellite and Model data. The WCT also provides access to weather/climate web services provided from NCEI and other organizations.

The WCT provides tools for background maps, animations and basic filtering. The export of images and movies is provided in multiple formats. The data export feature supports conversion of data to a variety of common formats including GeoJSON, KMZ, Shapefile, Well-Known Text, GeoTIFF, ESRI Grid and Gridded NetCDF. These data export features promote the interoperability of weather and climate information with various scientific communities and common software packages such as ArcGIS, Google Earth, MatLAB, QGIS, R and many more. Advanced data export support for Google Earth enables the 2-D and 3D export of rendered data and isosurfaces.

Current data types supported:

  • CF-compliant Gridded NetCDF
  • Generic CF-compliant Irregularly-Spaced/Curvilinear Gridded NetCDF/HDF
  • GRIB1, GRIB2, GINI, GEMPAK, HDF (CF-compliant) and more gridded formats
  • GOES Satellite AREA Files
  • NEXRAD Radar Data (Level-II and Level-III)
  • U.S. Drought Monitor Service (from the National Drought Mitigation Center (NDMC))
  • OPeNDAP support for Gridded Datasets
