APPARATUS AND METHOD FOR PRECIPITATION ESTIMATION

摘要

The present invention relates to a device and a method for estimating rainfall intensities The device for estimating rainfall intensities comprises: a radar observation part for generating data on radar rainfall intensities using radar; multiple rain gauges for measuring rainfall intensities at different positions of the ground; a rain gauge observation part for generating data on the ground rainfall intensities; and a radar rainfall intensity adjusting part for adjusting the data on the radar rainfall intensities using data on the distribution of the ground rainfall intensities having mutual relation therewith. The radar rainfall intensity adjusting part calculates the error distribution of the radar rainfall intensities by a co-kriging method using the error data between the data on the radar rainfall intensities and the data on the ground rainfall intensities as a main parameter and the data on the distribution of the ground rainfall intensities corresponding to the data on the ground rainfall intensities as a secondary parameter.
