As winter approaches, northern dwellers will get help from place to serve them present the rough weather.Satellite information on snow cover is now available through ESA`s GlobSnow project soon afterwards it snows. As good as posing a chance to communities through transportation shutdowns and floods, snow cover is one of the most crucial elements influencing the planet`s climate, meteorology and water systems. Understanding snow conditions helps us to predict floods and advance climate studies. Seasonal changes in snow cover mostly come in the northern hemisphere. The mean winter expanse in these regions affects 20-40 million sq km, with an equivalent water volume of 2000-3000 cubic km - about 1 000 000 000 Olympic-sized swimming pools.

The thinness of meteorological networks on the ground, especially in the outback areas of Eurasia and North America, makes it hard to map and measure the number of snow. GlobSnow, led by the Finnish Meteorological Institute, overcomes these limitations to improve information on snow characteristics in the northern hemisphere by using European and US Earth observation satellites. The one-year, near-real time demonstration service makes information about snow cover and snow amount publicly available online on the GlobSnow website. A number of northern institutes will run the information for use in hydrological modelling, flood forecasting and water resources management.
