This dataset contains global precipitation observations combined from satellite and rain gauge data over ocean and over land, respectively. It spans the years 1988-2015 and has a spatial resolution of 2.5°×2.5°, 1.0°×1.0°, and 0.5°×0.5° (Europe). Satellite observations are based on SSM/I Level 2 and SSMIS data of the HOAPS 4.0 dataset of CM SAF (DOI: 10.5676/EUM_SAF_CM/HOAPS/V002 ). These data have been extended with observations from the AMSR-E and TMI microwave imager platform. The basic rain rate retrieval is based on a neuronal network approach. The retrieval excludes sea-ice covered regions. Uncertainty estimations are given as standard deviation of pixel values in one grid cell. Precipitation observations over land are included from the GPCC Full Data Daily Version 2018 product (DOI: 10.5676/DWD_GPCC/FD_D_V2018_100 ). Relative precipitation anomalies at the stations are interpolated by means of ordinary block kriging. For these data, uncertainty information is included as well. On coastal edges data gaps are interpolated. This dataset is recommended to be used for analyses of extreme events and related statistics at daily resolution as well as for verification and validation purposes of other precipitation products or climate models.This dataset is a successor of the HOAPS/GPCC global daily precipitation data record version 1 (10.5676/DWD_CDC/HOGP_050/V001, 10.5676/DWD_CDC/HOGP_100/V001, and 10.5676/DWD_CDC/HOGP_250/V001). This dataset has been created within the DAPAGLOCO project (Daily precipitation analysis for the validation of global medium-range climate predictions operationalized). The DAPAGLOCO project was part of the MiKlip project framework (Mittelfristige Klimaprognosen) and funded by the German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung, BMBF).
