Modeling with SCHNAPS: the Snow Cover and High-resolutioN Atmospheric Processes System

Mass and energy exchanges between the cryosphere and the atmosphere affect the state of both systems, motivating the development of two-way coupled cryosphere-atmosphere models. For snow-atmosphere models, traditional atmospheric models are coupled to multilayer physics-based snow models and run in a large-eddy mode when simulating horizontal resolutions approaching 100m. For the CRYOWRF model in particular, the atmospheric model WRF was coupled to the snow model SNOWPACK. This approach has enabled detailed studies of snow-atmosphere feedbacks such as sublimation of drifting and blowing snow. However, the high computational cost of CRYOWRF limits its application to short spatio-temporal domains at scales relevant to drifting and blowing snow (
