database, solar radiation, quality check

A database containing 10 min means of solar irradiance measured on a horizontal plane in severalultraviolet and visible bands from July 2014 to December 2016 at three stations in the area of the city of Ostrava(Czech Republic) is presented. The database contains time series of 10 min average irradiances or photosyntheticphoton flux densities measured in the following spectral bands: 280-315 nm (UVB); 315-380 nm (UVA); and400-700 nm (photosynthetically active radiation, PAR); 510-700 nm; 600-700 nm; 610-680 nm; 690-780 nm;400-1100 nm. A series of meteorological variables including relative air humidity and air temperature at surfaceis also provided at the same 10 min time step at all three stations, and precipitation is provided for two stations.Air pressure, wind speed, wind direction, and concentrations of air pollutants PM10, SO2, NOx , NO, NO2 weremeasured at the 1 h time step at the fourth station owned by the Public Health Institute of Ostrava. The details ofthe experimental sites and instruments used for the measurements are given. Special attention is given to the dataquality, and the original approach to the data quality which was established is described in detail. About 130 000records for each of the three stations are available in the database. This database offers a unique ensemble ofvariables having a high temporal resolution and it is a reliable source for radiation in relation to environment andvegetation in highly polluted areas of industrial cities in the of northern mid-latitudes. The database has beenplaced on the PANGAEA repository (https://doi.org/10.1594/PANGAEA.879722) and contains individual datafiles for each station.
