Another snow sensor called a snow pillow looks like a round bag lying on the ground. Inside the pillow is a liquid such as an environmentally safe [citation needed] antifreeze. Usually the snow pillow will be connected to a manometer. The manometer reading will vary based on how much snow is sitting on the pillow.
The same SNOTEL site in Nevada. The large panel in the foreground is the snow pillow. Basic SNOTEL sites have a pressure sensing snow pillow, storage precipitation gauge, and air temperature sensor. However, they can accommodate 64 channels of data and will accept analog and parallel or serial digital sensors.
Snow is an important consideration for loads on structures. To address these, European countries employ Eurocode 1: Actions on structures - Part 1-3: General actions - Snow loads. [85] In North America, ASCE Minimum Design Loads for Buildings and Other Structures gives guidance on snow loads. [86]
Snow accumulation on ground and in tree branches in Germany Snow blowing across a highway in Canada Spring snow on a mountain in France. Classifications of snow describe and categorize the attributes of snow-generating weather events, including the individual crystals both in the air and on the ground, and the deposited snow pack as it changes over time.
The climatic snow line is the boundary between a snow-covered and snow-free surface. The actual snow line may adjust seasonally, and be either significantly higher in elevation, or lower. The permanent snow line is the level above which snow will lie all year.
Snow and blowing snow advisory WSW – Sustained winds of 25 to 35 miles per hour (40 to 56 km/h) are expected to be accompanied by falling and blowing snow, occasionally reducing visibilities to 1 ⁄ 4 mile (0.40 km) or less for at least three hours. Discontinued beginning with the 2008-2009 winter storm season and replaced by the winter ...

METAR is a format for reporting weather information. A METAR weather report is predominantly used by aircraft pilots, and by meteorologists, who use aggregated METAR information to assist in weather forecasting.
