Estimates of submicron particulate matter (PM1) concentrations for 1998–2022 across the contiguous USA: leveraging measurements…
The dominance of PM1 in PM2·5 reduction and the decreasing PM1/PM2·5 ratio reflect
the strong association of PM1 with fossil fuel and other combustion sources and their
responses to air quality regulations during the 25-year study period. The gradual
