The Pathfinder Program was established to develop remote-sensing data sets to support global change research and to enable NASA to gain experience in reprocessing and transferring large data sets between national and international research facilities. Pathfinder data sets consist of long time series of global and regional data as well as higher-level data products generated by NASA and other federal agencies.

, a component of the DAACs, distributes the polar Pathfinder data sets to the scientific community as part of its many responsibilities related to cryospheric research. In parallel to the polar Pathfinder program, a related group of data sets is being developed through the Polar Exchange at the Sea Surface (POLES)

To assist in planning how data sets will support polar science in the future and how data products may best be tailored to support the Earth Science Enterprise program, NASA asked the National Academies for guidance. In response, the Committee to Review NASA's Polar Geophysical Data Sets was created to review NASA's strategy for providing derived geophysical data sets to the polar science community.

The committee interpreted its charge as providing an assessment of current NASA polar geophysical data set products and recommendations to guide future decisions about the products. Rather than assess the details of specific data sets, the committee took a broad approach and based its assessment on the science questions outlined in the Earth System Enterprise program (NASA, 1988)

New EOS-era sensors will fill in some details, to be sure, but data records from these sensors for studying change will not be available for many years, if they indeed receive continued support for "long-term" monitoring. Various recommendations in Chapter 5 focus on the use of existing data sets in the more general contexts of ESE science and change detection, and also in the more specific context of NASA's DAACs and their provision of useful data sets to the science community.
