SNOW MAP VALIDATION FOR NORWAY

摘要: met.no has published snow accumulation maps for Norway more than 50 years. During the winter 2003-2004 new methods are developed by NVE and to produce accounting melting, refreezing rain. The daily products updated on a weekly basis. Spatial estimation of air temperature precipitation is applied observations from Norwegian meteorological network. A model used simulate water equivalent (SWE), liquid content runoff 1x1 km 2 one-day resolution. This paper presents results validation experiments. main against data 100 catchments (most have >20 at annual maximum). Simulations compared pillow observations, as well simulation observation two large catchments. show very good agreement between simulated observed SWE in terms deviation normal. Observed geographical patterns reproduced all over country, including years extremes. Simulated millimetres agree with northern central parts Norway, although overestimated some areas south: probably due interpolation precipitation.
