Fig. 3: Changes in SW radiation fluxes and PM2.5 concentration during smoke cover.
From: Wildfire smoke reduces lake ecosystem metabolic rates unequally across a trophic gradient
a Density plot of daily average SW radiation and (b) daily average PM2.5 concentration on non-smoke (n = 694; blue) and smoke (n = 349; gray) days. Dashed horizontal lines show median values across 9 unique meteorological datasets. c, d The cumulative deficit of SW radiation due to smoke cover (solid colored lines) from July 1 (doy 183) to Nov 1 (doy 306) in 2020 and 2021 at our study sites (line color corresponds with study site). Horizontal sections of the lines represent non-smoke days, vertical sections represent smoke events. Datasets that are spatially proximate have been omitted from panels c, d. Castle Lake’s cumulative SW deficit is not shown because only data from 2018 were available. Data were not collected from the Delta site in 2021.
