| Outline of Final Research Achievements |
To monitor long range transported aerosol particle event, a polarization optical particle counter (hereinafter referred to as POPC) was installed in various sites of East Asia including the mountains. The POPC's observation network was constructed. We also created a web system of the measurement result released in real time. Examination of extraction method of long range transport events using observation results at multiple points and examination of mass concentration estimation method for each composition by POPC were carried out.
A period in which the period exceeding the set threshold overlapped at multiple points was judged as a long range transport event. Results consistent with other observation results were obtained. Using the response function considering the finer particle size range and the complex refractive index for each composition was used, the mass concentration estimation was greatly improved.
