            <gco:CharacterString>Ground based in situ observations of aerosol_absorption_coefficient at K-puszta (HU0002R) using filter_absorption_photometer. These measurements are gathered as a part of the following projects ACTRIS, EMEP, GAW-WDCA, NOAA-ESRL and they are stored in the EBAS database (http://ebas.nilu.no/). Parameters measured are: aerosol_absorption_coefficient in pm10, aerosol_absorption_coefficient in pm10, aerosol_absorption_coefficient in pm10</gco:CharacterString>
