Quality control of radar data for NWP assimilation usingProRad and ConRad

This document gives a short overview of the ProRad system, and its capabilities regarding filtering of weather radar data for NWP assimilation. ConRad is also described, a tool for converting radar data between various formats. ProRad and ConRad can work together to allow vendor specific formats to be filtered by ProRad, and converted to the format required by HARMONIE. The core part of ConRad, and the quality control framework of ProRad, have been developed as part of a partially externally financed project with the Norwegian hydro power industry (NFR project ES439901/193048, NFR - The Research Council of Norway, RCN). ConRad is released as open source software, under GPLv2. ProRad will soon be available as open source software under the same licence. A fully functional data chain from raw radar data, via quality control and format conversion, to updates of the model state is reported. This system is flexible, and well suited for implementation of further QC algorithms, and resilient with respect to file format changes.
