During the TIFAX 2010 ((Thick Ice Feeding Arctic Export) campaign, conducted in August 2010 over Greenland height dependent aerosol optical depth (AOD) in the spectral range from 350 nm to 1050 nm with the airborne Sun photometer SPTA were measured. Observations were performed on board of the Alfred-Wegener-Institute research aircraft Polar 5 during 6 flights between the 17 August 2010 up to 23 August 2010 with the operation base Station Nord (81° 36′ N, 16° 40′ W). Based on the height dependent aerosol optical depth for four selected wavelengths (414 nm, 500 nm, 861 nm, 1026 nm) and the Ångström parameter Alpha (spectral slope) and Beta (AOD at 1000 nm) between 46 m and 4975 m the extinction coefficient (AOD per kilometer) can be calculated for selected wavelengths, for example for LIDAR or satellite comparison and validation. For special comparison is also the height angle of the Sun included.
