This paper describes a modified RainGaugeQC system for real-time quality control of rain gauge measurements made every 10 min. It has been significantly modified to control data from non-professional and private measurement networks of lower quality than professional data. The modifications went in the direction of performing more sophisticated data control, applying weather radar data, and taking into account various aspects such as consistency analysis of data time series and bias detection.

During the flooding of the Oder River in Sep 2024, daily rainfall exceeded 200 mm. The reliability of high-resolution rainfall estimates available in real time was assessed: from rain gauges, radars, satellites, unconventional & multi-source, also reanalyses. Rain gauges, adjusted radar & multi-source estimates showed the highest accuracy, unconventional methods slightly lower. Numerical weather prediction models still offered reasonable reliability, but satellite estimates were less effective.

The quality control of sub-hourly rain gauge data is a challenging task due to the high variability and low spatial consistency of the data. We developed an innovative approach to the quality control of telemetric rain gauge data focused on assessing the reliability of individual observations. Our scheme employs weather radar data to detect erroneous rain gauge measurements and to assess the data reliability. The scheme is used operationally by the Polish meteorological and hydrological service.

Short summary
Weather radar data are used in weather monitoring and forecasting, but they are affected by numerous errors and require advanced corrections. Different systems are designed and implemented to suit specific local conditions, like the RADVOL-QC system. The radar errors are divided into several groups: disturbance by non-meteorological echoes (from the mountains, RLAN signals, wind turbines, etc.), beam blockage, attenuation, etc. Each of them has different properties and is corrected differently.

Short summary
A data-processing algorithm, RainGRS Clim, has been developed to work on precipitation accumulations such as daily or monthly totals. The algorithm makes the most of additional opportunities: access to high-quality data that are not operationally available and greater efficiency of the algorithms for data quality control and merging for longer accumulations. Monthly accumulations estimated by RainGRS Clim were found to be significantly more reliable than accumulations generated operationally.
