Software to convert NCEP-grib1/grib2 files to HIRLAM-GRIB format to enable running MATCH

This document describes the software developed to convert the numerical weather prediction data calculated by NCEP/GFS model and provided in GRIB format to HIRLAM-GRIB format which is used by the far-range model of atmospheric transport MATCH of the RODOS system. The software also enables possibility to reverse u- and v-velocity components for running backward calculations. When using this software please cite the following paper: Kovalets I. V., Robertson L., Persson C., Didkivska S.N., Ievdin I.A. Trybushnyi D.
