Abstract :
High frequency (ν>100 GHz) observations from AMSU-B during the March 5-6, 2001 New England blizzard are used to investigate the detection of snowfall over land. The AMSU-B data are compared to NEXRAD reflectivities. The radiative effects of a snow model are compared with observations. Low altitude water vapor is shown to obscure emission from the underlying ground at high frequencies, but at high altitudes water vapor also reduces the impact of scattering by snow particles.
