Rain rate characteristics in Warsaw and in Dubna

In the years 1985-90, in frames of Intercosmos program, the measurements of 1-min average rain rate were conducted in Dubna (Russia) and in the years 1986–91 in Warsaw (Poland). In Dubna two or three tipping-bucket rain rate gauges were spaced out along the wave propagation experimental path and in Warsaw — five such sensors. Moreover in Warsaw 1-minute rain rate samples were applied for conversion of 1-minute rain rate distribution into 5-minute (10- and 20-minutes) rain rate distributions. The results of measurements and 1-minute rain rate samples conversion are presented in the paper.
