Description
Within the framework of the COST Innovators Grant (CIG) setGMDI, the Global Microwave Data collection Initiative (GMDI) will be implemented and applied to advance the project’s objectives. GMDI aims at collecting CML data from Mobile Network Operators (MNO), performing data analysis, data archiving, and deriving and providing gridded precipitation data. Within the CIG GMDI will start performance with data from pilot regions in Europe and Africa.
We will present comparisons of the CML-based precipitation fields to two global precipitation analysis products of the Deutscher Wetterdienst (DWD): the gridded gauge-based precipitation analysis of the Global Precipitation Climatology Centre (GPCC) operating under the umbrella of the World Meteorological Organization (WMO) and the satellite-based precipitation estimate GIRAFE of the Satellite Application Facility on Climate Monitoring (CM SAF) that is hosted by DWD on behalf of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT).
GPCC collects world-wide in-situ data from more than 129.000 stations, performs semi-automated quality control, data archiving and interpolation of precipitation data to gridded analysis products. Products comprise daily and monthly precipitation data, long-term means, the GPCC drought index as well as the HOMogenized PRecipitation Analysis for climate applications HOMPRA.
The Global Interpolated RAinFall Estimation (GIRAFE) is a fully satellite-based climate data record for precipitation merging observations by low-earth orbiting and geostationary satellites with a resolution of 1° x 1° currently spanning from 2002 till 2022 (regular extension operational in Q2 2026) providing daily and monthly data.
CML data have the potential to provide additional precipitation information especially in sparsely monitored regions. This study aims at exploring applications in precipitation monitoring and ground validation of satellite products, respectively.
