Radar-derived precipitation estimates can be substantially adjusted by rain gauge data. Whereas the real-time adjustment procedure is based on data from automatic gauges only, the retrospective analysis can utilize daily totals from much denser rain gauge network (Sokol, 2003; Sokol and Bližňák, 2009). This study verifies such estimates by sub-daily precipitation intensities from rain gauges for the warm seasons (May-September) of the years 2002-2012 in the area of the Czech Republic (CR). The length of accumulation period ranges between 10 min and 24 hours (10 min, 30 min, 1 h, 2 h, 3 h, 6 h, 12 h and 24 h) and the accumulations are continuous in time with a time step of 10 min. The rain rates were calculated using radar reflectivity data at 2 km above sea level measured by two Czech C-band Doppler radars (Brdy, Skalky) every 5 (since June 2009 onwards) and 10 min in 1 km by 1 km square boxes over the whole area of the CR.
