Ground based in situ observations of precip at Viana do Castelo (PT0003R) using precip_gauge, bulk_sampler. These measurements are gathered as a part of the following projects CAMP, EMEP and they are stored in the EBAS database (http://ebas.nilu.no/). Parameters measured are: precipitation_amount_off in precip (mass_concentration_of_precipitation_amount_off_in_precipitation), cadmium in precip (mass_concentration_of_cadmium_in_precipitation)
