AB  - This data is about the distribution and general properties of frozen soil and seasonal frozen soil in the Mongolian Republic.   1. The data consists of two layers: the frozen soil zoning map 1:12000000, which includes continuous and discontinuous permafrost, insular and sparsely insular permafrost, sporadic permafrost, and seasonally frozen ground.  2. Frozen soil type map 1:450000, divided into 14 types based on altitude, annual average temperature, frozen soil depth, freeze-thaw depth, seasonal frozen soil, and seasonal freezing depth.   3. The data includes the following layers:  cryo_landslide.shp（point locations of cryogenic landslides）、cryo_planation.shp（point locations of cryogenic planation）、dig_country_bnd.shp（digitized country boundary polygon from the 1:4,500,000 map）、dig_lakes.shp（digitized lake polygons from the 1:4,500,000 map）、treams.shp （digitized stream vectors from the 1:4,500,000 map）、geocryo_regions.shp （digitized geocryological region polygons from the 1:12,000,000 map. See the attribute description below）、geocryology.shp（digitized polygons of areas with detailed geocryological information from the 1:4,500,000 map. See the attribute description below）、icings.shp（point locations of icings）、 per_frost_mound.shp（point locations of perennial frost mounds）、solifluction.shp（point locations of solifluction）、thermokarst.shp（point locations of thermokarst）。   4.
