Abstract:
During the HALO-AC3 2022 (HALO – Arctic Amplification) campaign, conducted in March and April 2022 in the vicinity of Svalbard 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 10 flights between the 20 Mach 2022 up to 07 April 2022 with the operation base Longyearbyen (78° 13′ N, 15° 38′ E). Based on the height dependent aerosol optical depth for four selected wavelengths (414 nm, 496 nm, 861 nm, 1026 nm) and the Ångström parameter Alpha (spectral slope) and Beta (AOD at 1000 nm) between 27 m and 3070m 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 pf the Sun included.
