RAINFALL ESTIMATION APPARATUS USING 3-DIMENSIONAL GRID DATA ESTABLISHING FROM RADAR OBSERVATION DATA

摘要

The present invention relates to an apparatus for estimating rainfall. The present invention provides the apparatus for estimating the rainfall by converting radar observation data with respect to a certain region into a grid to generate grid data, the apparatus comprising: a reception unit which receives the radar observation data; a grid data generation unit which accumulates a plurality of grid layers respectively corresponding to a plurality of reference altitudes to be converted into a grid to prepare a multi-layered data structure, and interpolates a radar observation value in a center of grid cells constituting a row and a column of the grid layers based on the radar observation data to generate grid data having a multi-layered shape; and a estimation unit which estimates ground rainfall of a relevant region by multiply using the grid data of the grid layers. According to the present invention, the rainfall is estimated by using three-dimensional grid data of a multi-altitude, thereby considerably reducing an error according to effects of a cloud and topography disposed according to an altitude.
