Assisted by Ramesh Gautam, left, Sean de Guzman, chief of snow surveys for the California Department of Water Resources, measures the depth of the snowpack during the second snow survey of the ...
All SNOTEL sites measure snow water content, accumulated precipitation, and air temperature. Some sites also measure snow depth, soil moisture and temperature, wind speed, solar radiation, humidity, and atmospheric pressure. These data are used to forecast yearly water supplies, predict floods, and for general climate research.
The snow gauge suffers from the same problem as that of the rain gauge when conditions are windy. If the wind is strong enough, then the snow may be blown across the wind gauge, and the amount of snow fallen will be under-reported. However, due to the shape and size of the funnel, this is a minor problem.
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.
Here's how we compiled the list: We pored through 30-year average snowfall statistics of hundreds of locations in the U.S. from 1991 through 2020. We considered only those towns and cities with a ...
Snow forecast: Will it snow today? Overall, the snowiest cities in the U.S. are in western New York, while the snowiest parts of the U.S. are the mountains of the West and Alaska.
The National Snow and Ice Data Center (NSIDC) is a United States information and referral center in support of polar and cryospheric research.NSIDC archives and distributes digital and analog snow and ice data and also maintains information about snow cover, avalanches, glaciers, ice sheets, freshwater ice, sea ice, ground ice, permafrost, atmospheric ice, paleoglaciology, and ice cores.
The Northeast snowfall impact scale (NESIS) was created to measure snowstorms in the U.S. Northeast in much the same way the Saffir–Simpson hurricane scale records hurricane intensity and the enhanced Fujita scale with tornadoes. This scale takes into account the very high population of the Northeast, and thus snowfall amounts are often ...
