Ground based in situ observations of wet_only_sampler at Chopok (SK0002R). These measurements are gathered as a part of the following projects EMEP and they are stored in the EBAS database (http://ebas.nilu.no/). Parameters measured are: precipitation_amount in precip (lwe_thickness_of_precipitation_amount), iron in precip (mass_concentration_of_iron_in_precipitation), zinc in precip (mass_concentration_of_zinc_in_precipitation)
