SNOTEL sites make use of meteor burst communications technology. SNOTEL uses meteor burst communications technology to collect and communicate data in near-real-time. VHF radio signals are reflected at a steep angle off the ever-present band of ionized meteors existing from about 50 to 75 miles (80 to 120 km) above the earth.
The first use of snow gauges were precipitation gauges that was widely used in 1247 during the Southern Song dynasty to gather meteorological data. The Song Chinese mathematician and inventor Qin Jiushao records the use of gathering rain and snowfall measurements in the Song mathematical treatise Mathematical Treatise in Nine Sections. The book ...
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.
Thanks primarily to lake-effect snow, the USA's snowiest big city is Syracuse, New York, which gets about 11 feet of snow per winter season, the National Weather Service said. It's also one of the ...
Large dimensions (e.g. 3 m × 3 m) of the pillow prevent any bridging that might occur from having an effect on the measurement readings. For snow pressure measurement on roofs using a smaller snow pillow (e.g. 1 m × 1 m) is the better choice, because of the weight of the filling of the snow pillow.
