Precipitation totals and air circulation types in the Sudetes in 1961–2020

The database includes monthly and daily precipitation totals for Polish, Czech and German measuring stations in the Sudetes from 1961 to 2020. The source of the data was the Institute of Meteorology and Water Management - National Research Institute (https://danepubliczne.imgw.pl/), the Czech Hydrometeorological Agency (https://www.chmi.cz/historicka-data/pocasi/denni-data) and the German Weather Service (https://opendata.dwd.de/climate_environment/CDC/observations_germany/).
The daily data set additionally includes atmospheric circulation types assigned to a specific day, along with their classification components (advection direction, lower and upper vorticity and air mass humidity). A relevant atmospheric circulation type for a given day was calculated on the basis of data from ERA5 Reanalysis prepared by European Centre for Medium-Range with the spatial resolution 0.25° x 0.25°: the u and v wind components from 700 hPa isobaric level, geopotential from 850 hPa and 500 hPa isobaric level (https://cds.climate.copernicus.eu/datasets/reanalysis-era5-pressure-levels?tab=download) and total column water vapor (https://cds.climate.copernicus.eu/datasets/reanalysis-era5-single-levels?tab=download).
