Abstract
Results of measurements of the amount of precipitation with an OPTIOS optical precipitation gauge together with a standard Tretyakov O-1 gauge during three summer months of 2020 are presented; a good agreement between the measurement results is shown. The comparison of the OPTIOS readings with the readings of a similar optical rain gauge mounted at a distance of 3 km, as well as with related data of the Tomsk weather station of the Roshydromet network located at a distance of 6 km, shows significant spatial variations in the characteristics of atmospheric precipitation. A possibility of using OPTIOS both as an automated gauge within a weather station and as a component of an observation precipitation gauge network is shown.
