Abstract: Several of the GES DISC data sets can be converted from HDF4 or GRIB format into NetCDF (with COARDS-compliant dimensions) to make them easy to use in tools such as GrADS, Panoply, IDV and McIDAS-V. This service is available as an on-the-fly web service, invoked via URL, for selected Level 3 gridded datasets as well as a small number of Level 2 swath datasets. The service can be accessed through the Mirador search tool, http://mirador.gsfc.nasa.gov.
