Analysis of accumulated precipitation based on information from weather stations

Abstract

Abstract Knowledge about the spatial-temporal distribution of precipitation is important for a multitude of scientific and operational applications, and in agricultural monitoring particularly. Due to the irregularity of the network of meteorological stations and their small number in Central Siberia, a problem arises of filling in the missing data. Different ways are possible to solve this problem. This article addresses the problem of comparing data on the amount of accumulated precipitation received from ground-based weather stations and processed in various ways to reconstruct the spatial picture. Data analysis show that of all options considered, the use of a unified NOAA CPC dataset seems more appropriate in further agro-climatic studies. Only the satellite data can provide more complete and more accurate information.
