Polarcat As0831

Picture taken in the North Cape area during the flight as0831 of the POLARCAT Spring campaign (April 2008), from the Safire ATR-42 scientific aircraft. POLARCAT's main scientific goal was the quantification of pollution from mid-latitude to the Arctic. The canister under the wing is the particle measuring system for aerosols. Our own DOAS instrument was measuring aerosol extinction and NO2 and is described in Merlaud et al. Airborne DOAS measurements in Arctic: vertical distributions of aerosol extinction coefficient and NO2 concentration, ACP, 2011 (doi:10.5194/acp-11-9219-2011).
