Comparing instruments to get better snow measurements

Comparing instruments to get better snow measurements

Instruments that measure the water equivalent of snow were compared in a study, and recommendations were made for their use. This means that more reliable measurements will be available in the future.

In the study two automatic instruments used for measuring the water equivalent of snow were compared in four different locations to ascertain how well the different types of automatic instruments function in different conditions.  The locations included the Finnish Meteorological Institute in Sodankylä.  Information on the water equivalent of snow is important in forecasting floods, and with its help it is also possible to keep track of the extent of the snow cover in the Northern Hemisphere.
