High-resolution radiation and meteorological variables measurements for Ostrava, Czech Republic

A database containing irradiances of ultraviolet and visible components of the surface solar 10-minute irradiation measured from July 2014 to December 2016 at three stations in the area of the city of Ostrava (Czech Republic) is presented. The measured variables contain irradiances of UVB (280-315 nm), UVA (315-380 nm), intervals of 400-700 nm (photosynthetically active radiation, PAR), 510-700 nm, 600-700 nm, 610-680 nm (called 660 nm), 690-780 nm (called 730 nm), and global radiation (400-1100 nm). In addition, a series of meteorological variables including relative air humidity and air temperature is provided at the same 10-minute resolution at all stations. For two stations there are additional data: PM10, SO2, NOx, NO, NO2 concentrations, air temperature and relative humidity, air pressure, wind speed and wind direction. The details of the experimental sites and instruments used for the measurements are given. Special attention is given to the data quality while the process applied to label suspicious or erroneous measurements is described in detail. Between 93 and 99% of the measured values which were higher than threshold values for each spectral region of incident solar radiation are validated by this quality check. About 130 000 records for the all three stations are available in the database. Due to high temporal resolution of data, this database is a reliable source for estimation of radiation environment in highly polluted areas of industrial cities in the middle of Europe.
