Description

This paper presents assimilation of radar reflectivity using the Local Analysisand Prediction System (LAPS). Assimilation process has two stages. The first stage isdecoding of the reflecitivity from. vol or .xml formatted files (produced is by the nativeradar software) and writing it in the netCDF format, the format of all LAPS input data. The second stage is LAPS’s reflectivity analysis. Its first phase is projecting the dataonto the horizontal planes without taking into account data points present above andbellow. In the second phases vertical interpolation is performed, thus obtaining 3D fieldof the reflectivity.This separation in the data analysis greatly increases the speed of theanalysis, making LAPS very fast (efficient) system.
