Jessica E. Sanow, Steven R. Fassnacht, David J. Kamin, Graham A. Sexstone, William L. Bauerle, Iuliana Oprea
2018, Geosciences (8) 1-10
When applied to a snow-covered surface, aerodynamic roughness length, z0, is typically considered as a static parameter within energy balance equations. However, field observations show that z0 changes spatially and temporally, and thus z0 incorporated as a dynamic parameter may greatly improve models. To evaluate methods for characterizing snow surface roughness, we...
