Airborne measurement of ionic components in aerosol particles during AAMP98
During the Arctic Airborne Measurement Program 1998 (AAMP 98), atmospheric aerosols were collected onto PTFE filters from the inlet of Gulfstream II through a diffuser installed in the cabin. During the sampling the number concentrations of aerosol particles with diameters larger than 0.3 µm were co...
