Project: Atmospheric aerosol research in Greenland.

31-DEC-99 – 31-DEC-99

Aerosol collections are done at Summit, Greenland, with twe types of cascade impactors. The samples are analyzed by PIXE for about 20 elements. The data sets are converted into smooth size distributions, which are used to calculate the dry deposition velocities of the elements. These distributions also provide information on the aerosol source processes. Information on the source regions is obtained by relating the data to air mass trajectories.
