Arctic Study of Tropospheric Aerosol and Radiation (ASTAR) 2000: Arctic haze case study
The ASTAR 2000 (Arctic Study of Tropospheric Aerosol and Radiation) campaign ran from 12 March until 25 April 2000 with extensive flight operations in the vicinity of Svalbard (Norway) from Longyearbyen airport (78.25°N, 15.49°E). It was a joint Japanese (NIPR Tokyo)German (AWI Bremerhaven/Potsdam)...
