The database contains physical, chemical and meteorological data. Two research sub-periods can be distinguished in the dataset. In the period from 1996-04-03 to 1998-01-31, 57 cases were listed in the database. Then, there was no data until 2002. In addition, in the period from 2002-09-24 to 2017-07-11, 985 cases were listed in the database. The data refers to rain (R), snow (S) and sleet (RS) samples. Physical and chemical analyses include the measurements of 47 parameters. These include pH and EC, concentrations of the primary chemical constituents (Ca, Mg, Na, K, HCO3, SO4, Cl, PO4, Si – as colloidal SiO2) as well as secondary and trace constituents (Al, B, Ba, Fe, Mn, Sr, Zn, Hg, Cu, Li, Pb, Ni, Co, As, Be, V, Tl, Se, Mo, Sb, Ag, Cd, Br, I, Y, Bi, Ga, Te, Sn, W, Zr, Rb, U, Cr, Ti, Cs). Meteorological data include daily information (average from 24 h): air temperature (TEMP), visibility (VISIB), wind speed (WSPD) and precipitation volume (PRCP). VISIB is a parameter that determines the total dustiness of the air, regardless of the size of the particles of suspended dust. The mean (24h) concentrations of PM10 and SO2 measured on the day of occurrence of a precipitation episode at the CIEP monitoring point were also analysed (Chief Inspectorate for Environmental Protection - data are from the JPOAT 2.0 air quality database).
