Snow water equivalent (SWE) is the depth of water that would result if the snow mass melted completely, whether over a given region or a confined snow plot, calculated as the product of the snow height in meters times the vertically-integrated density in kilograms per cubic meter.

Snow Depth-This is a measurement from the snow surface to the ground in meters. It is commonly does over a large time span using immobile graduated stakes. Snow Water Equivalency - A measuring tool which represents the vertical depth of water that would accumulate in an area, if all the snow and ice were melted in that given area.
When snow is collected, the container is removed and replaced with a spare one. The snow is then melted while it is still in the container, and then poured into a glass measuring graduate. While the depth of snow is normally measured in centimetres, the measurement of melted snow (water equivalent) is in millimetres. [citation needed]
And here’s a fun fact from weather historian Christopher Burt: The greatest measured snow depth in the Northern Hemisphere was 466 inches (38.8 feet) in 1927 at Mt. Ibuki at an elevation of ...

The snow line is measured using automatic cameras, aerial photographs, or satellite images. Because the snow line can be established without on-the-ground measurements, it can be measured in remote and difficult to access areas. Therefore, the snow line has become an important variable in hydrological models. [2]
The U.S. record is 12 inches in a single hour. That happened in a lake-effect snow band east of Lake Ontario in Copenhagen, New York, on Dec. 2, 1966, according to a list of record snowfall rates ...
