Enhancement of storm detection capability of Czech weather radar network

The Czech weather radar network consists of 2 Doppler C-band weather radars (Gematronik Meteor 360 AC, EEC DWSR-2501C), covering the full territory of Czech Republic. To overcome the limitations of vendor software, an independent software library (RVD, written in C language) for volume data processing has been developed.

Wide range of products generated from volume data: reflectivity (incl. storm detection algorithms: VIL, Y-algorithm), precipitation (VPRs and VPR-corrected estimates) and Doppler wind (modified VAD algorithm) is available in user selectable resolution and geographical projection.

The software package, which is now in implementation phase, allows to use 1 km horizontal resolution of radar products (instead of previously used 2 km), enabling to display the fine structure of convective systems.
