Simulated Mean Annual Ground Temperature

These raster datasets are output from the Geophysical Institute Permafrost Lab (GIPL) model and represents simulated mean annual ground temperature (MAGT) in Celsius, averaged across a decade, at the base of active layer or at the base of the seasonally frozen soil column. These data were generated by driving the GIPL model with a composite of five GCM model outputs for the A1B emissions scenario. 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. These rasters cover the entire state of Alaska and has a spatial resolution of 2km.

notes These raster datasets are output from the Geophysical Institute Permafrost Lab (GIPL) model and represents simulated mean annual ground temperature (MAGT) in Celsius, averaged across a decade, at the base of active layer or at the base of the seasonally frozen soil column. These data were generated by driving the GIPL model with a composite of five GCM model outputs for the A1B emissions scenario. 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. These rasters cover the entire state of Alaska and has a spatial resolution of 2km.
