Historical hourly RADOLAN grid of precipitation height (GIS-readable)
收藏资源简介：
The routine procedure RADOLAN (radar online estimation) provides from the combination of the hourly values measured selectively at the precipitation stations with the precipitation detection of the 17 weather radars nationwide, spatially and temporally high-resolution quantitative precipitation data in real-time operation for Germany. Further information: https://opendata.dwd.de/climate_environment/CDC/grids_germany/hourly/radolan/historical/asc/BESCHREIBUNG_gridsgermany_hourly_radolan_historical_asc_de.pdf Current files are provided in the subdirectory “recent” in the original binary format approx. (hh+ 1):20 for the previous hour up to hh:50 or the following day in the ASCII GIS format automatically (by AFD).
