SPECTRAL ALBEDO OBSERVATION ON THE SNOW FIELD AT BARROW, ALASKA
Spectral albedo observation at the visible and near infrared wavelengths was carried out on the snow field at Barrow. Alaska in April, 1997. The data are compared with the theoretical calculations made by a multiple scattering radiative transfer model for the atmosphere-snow system using the snow ph...
