Global Estimates of Fine Particulate Matter from Space

The View from Afar – Satellite-Derived Estimates of Global PM2.5 (1 page pdf, Environmental Health Perspectives, Feb. 2, 2015)

Today we review research into recent global estimates of PM2.5 using space based sensors. Over the last decade, a trend toward worsening conditions in South and East Asia (with 51% more of the population exposed to pollution above WHO guidelines rose to 70%) and slightly improved conditions in the eastern USA and Canada (where the exposed population declined from 62% to 19%) was estimated from these satellite observations at a 10 km resolution. The authors expect in future that similar estimates may be made of NO2 concentrations at an improved resolution which may be more helpful in pin pointing urban pollution conditions and their sources.
