| Zusammenfassung |
| Multi-Source Weighted-Ensemble Precipitation (MSWEP) is a new fully global precipitation ($P$) dataset for the period 1979--2016 with a 3-hourly temporal and 0.1$^\circ$ spatial resolution. The dataset is unique in that it optimally merges a wide range of data sources based on gauges (GPCC, CPC Unified, and CHPclim), remote sensing (CMORPH, GSMaP-MVK, and TMPA 3B42RT), and weather models (ERA-Interim, JRA-55, and NCEP-CFSR) to provide the best possible $P$ estimates at global scale. Since its initial release in May 2016, MSWEP has undergone some major changes, such as (i)~increasing the spatial resolution from 0.25$^\circ$ to 0.1$^\circ$, (ii)~the correction of distributional $P$ biases, (iii)~the inclusion of ocean areas, (iv)~the addition of NCEP-CFSR $P$ data, (v)~the addition of infrared-based $P$ data (only for the pre-TRMM era), and (vi)~the inclusion of more gauge data. The effect of these changes on the performance has been assessed at global scale in two ways, using hydrological modeling for 9011 catchments ($ |
