Microanalytical Techniques for the Determination of Carbonaceous Aerosols in Remote Air and Snow Samples
Remote ice core, snow, and air filter samples can potentially profile past and present atmospheric characteristics, acting as media to preserve populations of particulate matter. Major constituents of these aerosols derive from combustion processes (fossil and biomass) and airborne minerals. Extract...
