Abstract
Measurements of atmospheric transmission during periods of snowfall were made in the visible and infrared during March and April 1985. The measurements are compared to transmission predicted by the XSCALE module of the Electro-Optical Systems Atmospheric Effects Library (EOSAEL). The XSCALE predictions correspond well with measured transmittances in the visible but predictions in the IR are considerably less than the measured values. This suggests that the snow transmittance algorithm used in XSCALE is more accurate for transmissometers whose receiver diameters are much larger than the beam diameter.
