Correction of Moistening, Evaporation, and Condensation in Measurements of Precipitation by a Tret’yakov Raingauge

E. G. Bogdanova and B. M. Il’in

On the basis of results of observations at 36 stations in Russia, the mean long-term annual and monthly values of a moistening correction introduced into the current mesurements of precipitation are compared with the total correction, including the effect of evaporation and condensation processes on the results of precipitation measurement by a Tret’yakov raingauge. The differences are shown between the annual and seasonal values of these corrections and their annual variation under different climatic conditions. A map is presented for the annual values of difference between the absolute andrelative types of corrections.
