Description

This data set contains rainfall rates estimated from X-band radar (WRX) observations during the Field Experiment on Sub-mesoscale Spatio-Temporal Variability in Lindenberg (FESSTVaL) from June to August 2021. This single-polarized, local area weather radar was located at the boundary layer field site of the German Weather Service (Deutscher Wetterdienst - DWD) at Falkenberg. The radar operated at an elevation angle of 2.3° with a high temporal 30 s, range 60 m, and sampling 1° resolution refining observations of the German nationwide C-band radars within a 20 km scan radius. The high-resolution rainfall rates are available as hourly NetCDF-files.

Limitations: Quality: Several sources of radar-based errors were adjusted gradually affecting the precipitation estimate, e.g. the radar calibration, alignment, attenuation, noise, non-meteorological echoes. However, a few azimuth angles of the measurements are affected by beam blockage. The WRX’s reflectivity values are calibrated and the derived rainfall rates are evaluated to measurements of a micro rain radar (MRR) located at the Lindenberg Meteorological Observatory – Richard Assmann Observatory (MOL-RAO) of the German Weather Service (DWD). The rainfall rates of the WRX and MRR are in good agreement. Some days have missing data, see this list of days and percentage available data: 10.07.2021 = 96 %; 09.08.2021 = 83 %; 23.08.2021 = 98 %; 24.08.2021 = 0 %; 25.08.2021 = 68 %
