Abstract:
The raster dataset displaying the soil temperature categories of Cryic and Frigid was developed from SSURGO soils attribute data, 10 meter DEMs and input from local USDA-NRCS soil scientists. The raster cell size is 10 meters and is provided in Montana State Plane meters coordinates. The cryic/frigid is coded with two values: Cryic = 1, Frigid = 2. A cryic soil temperature regime (thermal distribution) has a mean annual soil temperature of > 0 C but greater than 8 C, > 5 C difference between mean summer and mean winter soils temperatures, at 50 cm, and cold summer temperatures. Soils in this temperature regime have a mean annual temperature lower than 8 degrees C but do not have permafrost. In the American West, these areas have cryic soils: all areas above timberline, virtually all areas above the Douglas fir zone, and some areas within the Douglas fir zone. In addition, cold air (and water) drainage results in most mountain meadows within the Douglas fir zone (and even lower and into the Ponderosa pine zone) having cryic soils.] A frigid soil temperature regime (thermal distribution) has a mean annual soil temperature of > 0 C but greater than 8 C, less than 5 C difference between mean summer and mean winter soil temperatures at 50 cm below the surface, and warm summer temperatures.
Purpose:
For display of cryic and frigid soil temperature regimes across Montana.
