SEASONAL VARIATION OF CLOUDS AND PRECIPITATION IN NY-ALESUND, SVALBARD
We started radar observations of clouds and precipitation in Ny-Alesund, Svalbard, Arctic in August 1992. Although there were some no data periods because the station was not manned, we obtaied data from August 1992 to March 1995. Monthly precipitation was calculated from the 5 minutes mean radar re...
