Global Data Archive: Gridded

This page provides access to gridded data sets documenting spatial and temporal variability in various climate parameters:

The gridded data sets are written in network common data form (netCDF) conforming to the Cooperative Ocean-Atmosphere Research Data Service (COARDS) standard. The COARDS netCDF standard is described in this link.
