Ground based in situ observations of sulphate_corrected at Løken (NO0218R) using bulk_sampler. These measurements are gathered as a part of the following projects NILU and they are stored in the EBAS database (http://ebas.nilu.no/). Parameters measured are: sulphate_corrected in precip (mass_concentration_of_sulphate_corrected_for_seaspray_expressed_as_sulphur_in_precipitation), sulphate_corrected in precip (mass_concentration_of_sulphate_corrected_in_precipitation)
