Proceedings of SPIE Vol. 12341 : 28th International Symposium on Atmospheric and Ocean Optics: Atmospheric Physics, 2022, Tomsk, Russia. P. 123412U-1-123412U-4Abstract: This paper presents results of verification of recovered precipitation sums based on GPM IMERG microwave satellite measurements with standard observations at hydrometeorological stations in Western Siberia during summer period. The results revealed good agreement between GPM IMERG data and ground observations at the network of meteorological stations with a correlation coefficient of 0.987. The statistical analysis showed that the average discrepancy between daily precipitation sums according to GPM IMERG data and ground observations for all cases considered is 1.2 mm. The obtained accuracy of GPM IMERG data allows it to be used for most tasks.
