Contribution of Wildland-Fire Smoke to US PM2.5 and Its Influence on Recent Trends
Abstract
Seasonal-mean concentrations of particulate matter with diameters smaller than 2.5 μm (PM 2.5 ) have been decreasing across the United States (US) for several decades, with large reductions in spring and summer in the eastern US. In contrast, summertime-mean PM 2.5 in the western US has not significantly decreased. Wildfires, a large source of summertime PM 2.5 in the western US, have been increasing in frequency and burned area in recent decades. Increases in extreme PM 2.5 events attributable to wildland fires have been observed in wildfire-prone regions, but it is unclear how these increases impact trends in seasonal-mean PM 2.5 . Using two distinct methods, (1) interpolated surface observations combined with satellite-based smoke plume estimates and (2) the GEOS-Chem chemical transport model (CTM), we identify recent trends (2006–2016) in summer smoke, nonsmoke, and total PM 2.5 across the US. We observe significant decreases in nonsmoke influenced PM 2.5 in the western US and find increases in summer-mean smoke PM 2.5 in fire-prone regions, although these are not statistically significant due to large interannual variability in the abundance of smoke. These results indicate that without the influence of wildland fires, we would expect to have observed improvements in summer fine particle pollution in the western US but likely weaker improvements than those observed in the eastern US.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
