Comprehensive Measuremnt of atmospheric Aerosols with a Wide Range Aerosol Spectrometer

In this Paper, the measuring principle of a wide range aerosol spectromete (WRAS) with more than 70 size channels from 5.5 nm to 32 micrometer is introduced. Comprehensive measurements of atmospheric aerosols were performed with Grimm WRAS system at the Atmosphere Wathc (GAW) Statioon in Hohenpeissenberg in Germany. These wide range data were combined with simultaneous concentrations obtained from aerosol size distributions measured with the WRAS system were compared to TSI CPC counts and TEOM results, showing a good correlation. The correlation between these data aööows the source apportionment of particles, the investigaion of aerosol transport, transformation and mixing processes, as well as the research on the effect of atmospheric aerosols on the human health and climate.
