For the evergreen pine forest, we expect a weaker but observable correlation of CO2 fluxes with the canopy greenness data, GCC was calculated separately for four different, clearly identifiable vegetation types at the wetland site. The GCC values of the ROIs defined according to vegetation types showed significant differences in the seasonal cycle, both The daily mean GCC values of different canopy ROIs remained very similar throughout the time series (Fig. 9). Figure 6: Mean daytime (11.00–15.00) GCC of different Regions of Interests (vegetation types) during the measurement period of 9: Mean daytime (11.00–15.00) GCC values of different ROIs from two forest cameras during the measurement period of 	./cache/work_zfxd6auzx5bohlexqq4h7pqize.pdf	./txt/work_zfxd6auzx5bohlexqq4h7pqize.txt
