Variation of monthly precipitation and frequency of radar echo existence at some altitudes in Ny-Alesund, Svalbard, Arctic (scientific paper)

元データ 国立極地研究所


Atmosphere, precipitation, snow cover and glaciers have been observed or surveyed around Ny-Ålesund (78°55′N, 11°56′E) in Svalbard, Arctic for studying the Arctic climate and environment by scientists from Norway, Germany, Japan and other countries. The authors, especially, have observed characteristics of clouds and precipitation using vertically pointing radar and a 37 GHz microwave radiometer. There were two minimum peaks of precipitation in a year from monthly data obtained from the observations between August 1992 and March 1995. One of them was in January, when the monthly mean cloud amount was relatively small, and the other was in June, when the monthly mean cloud amount was relatively large.
