Snow Water Equivalent (SWE) is a common snowpack measurement. It is defined as the amount of water contained within the snowpack. These snowpack projections are produced by using a land surface/hydrology model known as the Variable Infiltration Capacity (VIC) model. The VIC model uses a gridded dataset of observed precipitation and temperature data as input to calculate SWE and a suite of additional parameters. Details are described in Livneh et al., 2015.
