Wondering how much snow has fallen near you? USA TODAY's detailed map lets you explore snowfall accumulation over the past 24, 48, and 72 hours. You can also check seasonal totals starting from ...
The use of active microwave data to map snow-cover characteristics is limited by the fact that only wet snow can be recognized reliably. The most frequently used methods to map and measure snow extent, snow depth and snow water equivalent employ multiple inputs on the visible–infrared spectrum to deduce the presence and properties of snow.
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]

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 ...
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]
