Fig. 2: Correlation between daytime FCOS and driving variables.
From: Examining anomalous summer carbonyl sulfide emissions in a boreal forest after thinning

Binned median correlation between daytime FCOS and environmental variables (a PAR, b Ta and c VPD) during June–July for each year. The half-hourly flux data is sorted equally into ten decile bins, and the shaded regions represent the interquartile range. The number of data points in each bin is indicated in the corresponding panel. The blue circle, red cross, and yellow triangle denote the post-thinning years 2020, 2021 and 2022, respectively.
