Ground based in situ observations of online_gc at Cape Verde Atmospheric Observatory (CV0001G)

Abstract:
Ground based in situ observations of online_gc at Cape Verde Atmospheric Observatory (CV0001G). These measurements are gathered as a part of the following projects ACTRIS, GAW-WDCGG-node and they are stored in the EBAS database (http://ebas.nilu.no/). Parameters measured are: 2-methylbutane in air (mass_fraction_of_2_methylbutane_in_air), 2-methylbutane in air (mass_fraction_of_2_methylbutane_in_air), 2-methylbutane in air (mass_fraction_of_2_methylbutane_in_air), benzene in air (mass_fraction_of_benzene_in_air), benzene in air (mass_fraction_of_benzene_in_air), benzene in air (mass_fraction_of_benzene_in_air), n-butane in air (mass_fraction_of_butane_in_air), n-butane in air (mass_fraction_of_butane_in_air), n-butane in air (mass_fraction_of_butane_in_air), n-pentane in air (mass_fraction_of_pentane_in_air), n-pentane in air (mass_fraction_of_pentane_in_air), n-pentane in air (mass_fraction_of_pentane_in_air), toluene in air (mass_fraction_of_toluene_in_air), toluene in air (mass_fraction_of_toluene_in_air), toluene in air (mass_fraction_of_toluene_in_air)
