AFGWC (Air Force Global Weather Central) Snow Analysis Model
Abstract
The AFGWC Snow Analysis Model, which generates daily snow age and depth analyses, has been operational since March 1975 for the Northern Hemisphere and October 1975 for the Southern Hemisphere. The snow analysis (SNODEP) model uses the latest observations (surface synoptic reports), snow and ice climatology, time continuity and manual updates. This makes it possible to produce very good measures of snow extent and reasonable snow depth values at all grid points over the land and the ice-covered areas of the earth, regardless of the availability of surface observations. The method of analysis, a technique used to infer snow age, and some problems associated with the input data are described. Although the model is tailored to satisfy specific AFGWC requirements, other potential applications are discussed.
