Filter samples of atmospheric aerosols have been or are being collected at these stations for chemical analysis of major inorganic ions and aerosol mass.  See Quinn et al. (2000) for a description of sampling and analysis methods. Sampling at many of the stations is done in cooperation with NOAA/ESRL/GMD.
