  <Summary>This data set includes monthly all-sky skin temperature data for areas in Alaska and northwestern Canada, between 55°N and 65°N, and 160W° and 110°W. These AVHRR Polar Pathfinder data are projected on the 25 km EASE-Grid, derived from the 5 km grid via subsampling. Data have better accuracy over oceans; some problems are readily apparent in land surface areas owing to snow cover mask. Data coverage is from 1990 through 2001. The data consist of X binary file downloads, containing monthly gridded output in EASE-Grid format. These data are archived at the Western Arctic Linkage Experiment (WALE) Web site.</Summary>
