Assessing the variability of snow surfaces
Variability in snow surface roughness is rarely incorporated into climate or hydrological models, yet it has the potential to have a large impact on both latent and sensible heat for a snow dominated system. We looked at the spatial variability of snow surface roughness using the data collected by the NASA Cold Land Processes Experiment (CLPX) during the winters of 2002 and 2003 for nine 1 km2 study sites across northern Colorado. Black boards were placed perpendicularly into the snow to create a contrast so that pictures could be taken of the surface. The surfaces digitally extracted and the ...
