Overview of the Czech Weather Radar Network - calibration and monitoring

Popis výsledku v původním jazyce

WXRCalMon workshop 18.-20.10. 2017, headquarters of DWD, Offenbach: poster contribution: 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. 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. On the other hand, polarimetric radars are more demanding for calibration and monitoring. The presentation will give an overview of the CZRAD network. Main focus will be given on the radar systems monitoring and calibration.
