Fig. 1: August trend analysis of atmospheric composition.
From: New seasonal pattern of pollution emerges from changing North American wildfires
August trend (2002–2018) in satellite-measured atmospheric composition is shown in a 1×1 degree grid. a Column carbon monoxide (CO) trends (n = 16) and b aerosol optical depth (AOD) trends (n = 17). Gray dots indicate significant non-zero trends, α = 0.05. Defined regions are outlined in black: Pacific Northwest (PNW, 38∘–57∘N, 127∘–110∘W), Central USA (35∘–49∘N, 110∘–95∘W), and the Northeast (41∘–53∘N, 95∘–74∘W). White areas outlined in gray denote missing data.
