Ground based in situ observations of bulk_sampler at Zoseni (LV0016R). These measurements are gathered as a part of the following projects HELCOM, 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), calcium in precip (mass_concentration_of_calcium_in_precipitation), sulphate_total in precip (mass_concentration_of_sulphate_total_in_precipitation)
