Snow water equivalent is a measure of the liquid water contained in snowpack. It is more useful than snow depth for estimating the volume of meltwater flow. This is because 3 feet of fresh, dry, fluffy snow may represent only 4-5 inches of SWE, but 3 feet of compacted, wet, spring snow may contain 12 inches or more of SWE. Using SWE helps scientists measure snowpack in a standardized way. Units are inches (in).
