Scattering coefficient, size distribution and the transport process of tropospheric aerosol in the Arctic region observed with an aircraft during ASTAR 2000/2004 and AAMP 2002 campaign in spring
Airborne aerosol measurements of the Arctic haze were carried out during three campaigns, Arctic Study of Tropospheric Aerosol and Radiation 2000 (ASTAR 2000), the Arctic Airborne Measurement Program 2002 (AAMP 2002) and ASTAR 2004. Aircraft used for the campaigns were Dornier for ASTAR 2000 2004 an...
