NSIDC Daily Precipitation Totals at Coastal and Island Russian Arctic Stations, 1940-1990

Petersburg, Russia, under the direction of Vladimir Radionov. Records from most stations begin in 1940.

Instrumentation was generally a rain gauge with Nipher shield until the early 1950s (for most stations), when the Tretyakov precipitation gauge replaced earlier instrumentation. Data have not been adjusted for gauge type or wind bias. Data from 1967 and later are corrected for wetting loss (this correction was made by observers as they recorded the station data).", quoted summary from NSIDC documentation.
