CZRAD - the Modern Dual Polarization Czech Weather Radar Network
The Czech weather radar network (CZRAD), operated by the Czech Hydrometeorological Institute (CHMI), covers entire area of the Czech Republic and vicinity using volume scan measurements of its two radars with 5 minute update rate up to 260 km range. The CZRAD data are used for severe weather and precipitation monitoring, nowcasting and warning by national civil and military weather services, operational hydrology, air traffic control and many other users including general public. In 2015, the CZRAD radars were completely replaced with new modern dual polarization Doppler weather radars Vaisala WRM-200. Upgrade of the CZRAD will ensure continuity of high quality radar measurements in next decades. A dual polarization capability of the new radars enable improve quality of standard radar reflectivity data (better filtering of non-meteorological data and attenuation correction) and also enable measurements of new radar quantities that can be used for radar echo classification. The presentation will summarized current technical parameters of the Czech weather radar network. It will discussed improvements of radar data after network upgrade. Utilization of the radar data in the CHMI operational applications will be also shown.
Dr. Petr Novák has been working in the Czech Hydrometeorological Institute since 1996. Currently, as a head of the Radar Department, he is responsible for operation of the Czech weather radar network. His main professional interests are radar data processing, nowcasting applications and remote sensing data visualization and interpretation. He is a graduate of the Faculty of Mathematics and Physics of the Charles University, where he got Master and PhD degree in meteorology.
