Ambient fine particulate matter (PM2. 5) is a leading environmental risk factor for premature
mortality. We use aerosol optical depth (AOD) retrieved from two satellite instruments, MISR …

Exposure to outdoor fine particulate matter (PM2. 5) is a leading risk factor for mortality. We
develop global estimates of annual PM2. 5 concentrations and trends for 1998–2018 using …

Background Epidemiologic and health impact studies of fine particulate matter with
diameter< 2.5 μm (PM2. 5) are limited by the lack of monitoring data, especially in …

Background: More than a decade of satellite observations offers global information about the
trend and magnitude of human exposure to fine particulate matter (PM2. 5). Objective: In this …

Although ground-level PM2. 5 (particulate matter with aerodynamic diameter< 2.5 μm)
monitoring sites provide accurate measurements, their spatial coverage within a given …

Annual global satellite-based estimates of fine particulate matter (PM2. 5) are widely relied
upon for air-quality assessment. Here, we develop and apply a methodology for monthly …

Epidemiologic and health impact studies are inhibited by the paucity of global, long-term
measurements of the chemical composition of fine particulate matter. We inferred PM2. 5 …

We estimated global fine particulate matter (PM2. 5) concentrations using information from
satellite-, simulation-and monitor-based sources by applying a Geographically Weighted …

We assess the relationship of groundlevel fine particulate matter (PM2. 5) concentrations
for 2000–2001 measured as part of the Canadian National Air Pollution Surveillance …

Ground-based observations have insufficient spatial coverage to assess long-term human
exposure to fine particulate matter (PM 2.5) at the global scale. Satellite remote sensing …
