Ground based in situ observations of aerosol_absorption_coefficient at DEM_Athens (GR0100B) using filter_absorption_photometer

Abstract:
Ground based in situ observations of aerosol_absorption_coefficient at DEM_Athens (GR0100B) using filter_absorption_photometer. These measurements are gathered as a part of the following projects ACTRIS, COLOSSAL, GAW-WDCA and they are stored in the EBAS database (http://ebas.nilu.no/). Parameters measured are: aerosol_absorption_coefficient in pm10
