Search and Order

Use the Graphical Interface for Subsetting, Mapping, and Ordering (GISMO) to search for Pathfinder data sets by collection, parameter (channel), and date. Or specify areas of interest, and the data will be subsetted spatially to reduce volumes.

The NOAA/NASA Pathfinder Program is designed to facilitate user access to earth science data sets that address global change concerns. The Polar Pathfinders, a subgroup of the Pathfinder Program, addresses the comparison of parameters from different data sets with a common projection, file naming conventions, and validation conventions. This ensures that consistently processed data sets are available to the cryospheric science community, for comparing and contrasting. See NSIDC DAAC: The NOAA/NASA Polar Pathfinder Program for more information.
