Evaluation of the measurement methods for PM2.5 mass concentration

摘要

Atmospheric aerosols have substantial effects on the Earths radiative forcing and have an adverse impact on human health. Due to its short atmospheric lifetime, distribution of aerosols shows large spatial and temporal variation even in regional scale. Especially, emissions of anthropogenic aerosols in Asian region have been changing significantly due to rapid economic growth and following emission constraint. For example, current aerosol emissions from Asian region are expected to have more contribution on global radiation budget than that of Europe and North America (Murphy, 2013). Thus precise long-term monitoring of aerosol properties from Asian region is needed to make better understanding of the impact on the Earth’s climate and human health.
