Description: Department of Atmospheric Sciences, University of Washington, Seattle, WA 98195, USA. We describe a novel inlet that allows measurement of both gas and particle molecular composition when coupled to mass spectrometric, chromatographic, or optical sensors: the Filter Inlet for Gas and AEROsol (FIGAERO). The design goals for the FIGAERO are to allow unperturbed observation of ambient air while simultaneously analyzing gases and collecting particulate...

Description: Leibniz Institute for Tropospheric Research, Permoserstr. 15, 04318 Leipzig, Germany. In the CALIPSO data analysis the surface type (land/ocean) is used to augment the aerosol characterization. However, this surface-dependent aerosol typing prohibits a correct classification of sea-breeze-related marine aerosol over land. This might result in a systematic overestimation of the particle extinction coefficient and of the aerosol optical thickness (AO...
