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

摘要

An apparatus for estimating a rainfall using grid data, the apparatus comprising: a receiver for receiving the radar observation data; a receiver for receiving the radar observation data; A plurality of grid layers each corresponding to a plurality of reference heights to be latticed are accumulated to form a multi grid layer data structure, and radar data at a grid cell center point constituting a row and a column of the grid layer based on the radar observation data, A grid data generator for generating grid data in the form of a multi-grid layer by interpolating observations; And a rainfall estimator for estimating a rainfall amount of the area by using the grid data of the plurality of grid layers in combination. According to the present invention, by estimating the amount of rainfall using multi-level three-dimensional grid data, it is possible to greatly reduce errors due to the effects of clouds and terrains positioned at altitude.
