The file name specifies the decade the raster represents. For example, a file named MAGT_1980_1989.tif represents the decade spanning 1980-1989. Cell values represent simulated mean annual ground temperature (degree C) at the base of the active layer (for areas with permafrost) or at the base of the soil column that is seasonally frozen (for areas without permafrost). If the value of the cell is negative,the area has permafrost and the cell value specifies MAGT at the base of the active layer. If the value of the cell is positive, the ground is only seasonally frozen and the cell value specifies MAGT at the base of seasonal frost.

The primary IFSAR dataset was acquired by Intermap Technologies and contracted by the Bureau of Land Management, U.S. Geological Survey, and the National Science Foundation. The raw data were collected with a STAR-3i airborne synthetic aperture radar system, a high-resolution, single pass, across track IfSAR system (Intermap, 2010). The Digital Surface Model (DSM) products represent the first reflective surface as illuminated by the radar. The STAR-3i system is capable of acquiring imagery with a horizontal accuracy better than 2 m, a vertical accuracy better than 1 m, and a vertical resolution on the order of 0.1 m (Intermap, 2010). Accuracy statements are based on areas of moderate terrain. Diminished accuracies are to be expected in areas of extreme terrain and dense vegetation. In addition, the DSM contains processing artifacts expressing as 30 to 50 cm high ripples or 'corn rows' that should be considered additional vertical error in the dataset. This striping results from uncompensated differential phase errors on very flat terrain. In addition, users will notice a seam line separating the tiles that were provided in UTM zone 5 with those provided in UTM zone 4. The differences along the seamline is within the 1m vertical accuracy of the dataset butthe variability is apparent here. The DSM data for 7.5-minute by 18-minute units correspond to the USGS 1:63,360 scale topographic quadrangle map series for available areas in the United States. Each 7.5-minute by 18-minute tile provides full coverage with overlap into adjacent tiles. The mosaic consists of 312 tiles.
