13. ABSTRACT (Maximum 200 words)
Snow is a crucial factor affecting the U.S. Army's operations in cold regions. Values for snow depth and
snow density are needed for vehicle mobility studies, but unfortunately the available historical records of
these parameters tend to be relatively sparse. This report deals with the estimation of snow density and
snow depth from readily available parameters such as air temperature and wind speed. As a basis for fur-
ther study, the authors have summarized previous work in three areas of particular interest to the U.S. Ar-
my's vehicle mobility programs: Korea, Germany and Alaska. Empirical models are presented for estimating
snow parameters in these regions.
