Ground based in situ observations of bulk_sampler at Ualand (NO0095R). These measurements are gathered as a part of the following projects EMEP, NILU and they are stored in the EBAS database (http://ebas.nilu.no/). Parameters measured are: precipitation_amount in precip (lwe_thickness_of_precipitation_amount), arsenic in precip (mass_concentration_of_arsenic_in_precipitation), iron in precip (mass_concentration_of_iron_in_precipitation), manganese in precip (mass_concentration_of_manganese_in_precipitation)
