Concentrations of major ions in wet precipitation samples in Austria

This dataset was compiled by the Research Group for Environmental Analytics - Institute of Chemical Technologies and Analytics, TU Wien. The precipitation data was gathered as part of the Austrian precipitation chemistry network. It contains precipitation amount, concentrations of major ions, pH and conductivity at several sites in Lower Austria, Salzburg, Styria and Tyrol.

The dataset includes the following columns:
Datum – date of the precipitation event, sampling takes place at the next day
Ort – sampling site location
NS – precipitation amount in mm
LF – conductivity in µS/cm
pH – pH value
NH4 – concentration NH4+ in mg/L
Na – concentration Na+ in mg/L
K – concentration K+ in mg/L
Ca – concentration Ca2+ in mg/L
Mg – concentration Mg2+ in mg/L
Cl – concentration Cl- in mg/L
NO3 – concentration NO3- in mg/L
SO4 – concentration SO42- in mg/L
Pb – concentration Pb2+ in µg/L
Cd – concentration Cd2+ in µg/L

In addition there are flag columns for every analyte. Used flags are:
1 – valid
4 – contaminated
7 – not available

The sampling was performed with WADOS – Wet And Dry Only Samplers by Kroneis. Anions and cations were mostly quantified with chromatographic systems. Lead and Cadmium concentrations are not available for every station and were measured with ICP-OES. pH and conductivity were measured with respective electrodes. For more detailed information on measurement see the annual reports on wet deposition, published by the federal governments of Lower Austria, Salzburg, Styria and Tyrol.

Code Availability

Python code for correct calculation of deposition is available at the Research Group for Environmental Analytics.
