Summary: Because of the cryospheres sensitivity, scientists turn to the worlds ice sheets, glaciers, snow cover, sea- lake- and river ice, ice caps and frozen ground, to learn more about past climate events, to understand current weather, and to project, on regional and global levels, what the future holds. However, true understanding depends on adequate representation of cryospheric processes and cryosphere-climate interactions in climate and hydrological models, and on our ability to monitor and understand variability exhibited by major ice sheets and hemispheric patterns of snow and sea ice extent. The difficulties inherent in comparing parameters from different data sets hamper even basic studies. To mitigate such obstacles, NASA and NOAA initiated the NOAA/NASA Pathfinder Program. The Polar Pathfinder Sampler CD-ROM is an innovative assemblage of atmospheric and surface measurements from all three Pathfinders. Included is a two-year period of daily merged Pathfinder data sets at 100 km-resolution, placed in a multidimensional structure known as the P-Cube. In addition, samples of full-resolution SSM/I, TOVS and AVHRR (both the 1.25 km and 5 km products) Polar Pathfinder data sets are included, also in EASE-Grid, making it easy to compare parameters at multiple resolutions. The new product provides data for a wide range of polar climate research applications, but is especially keyed to the needs of investigators dealing with large-scale atmospheric changes, surface heat and mass balance studies, and sea ice modelling.
