Fig. 3: Variation of canopy conductance with light and daytime FCOS.

Sapflow upscaled canopy conductance (GC) and its relation with PAR and FCOS during June–July of each year. a Box-whisker plot for daytime GC in low (10–250 μmol m−2s−1), medium (250–750 μmol m−2s−1) and high (>750 μmol m−2s−1) PAR conditions. The blue, red and yellow-coloured boxes denote the years 2020, 2021 and 2022, respectively. The solid diamonds, circles and squares in each box represent the mean values for 2020, 2021 and 2022, respectively. b Binned median correlation between daytime FCOS and GC (solid lines). The half-hourly data is sorted equally into ten decile bins, and the number of data points in each bin is given. Linear regression between daytime FCOS and GC (dashed lines). The blue circle, red cross and yellow triangle with solid lines denote the years 2020, 2021 and 2022, respectively. The shaded region represents the interquartile range.
