The authors modify the schematic plots in their article [1] showing the instrument set-ups in the graphical abstract and Figure 1 because the layout of the instrument set-up is not free of copyright and it was not properly cited [2]. In order to avoid any copyright infringements in the future, the schematic plots of the instruments in both the graphical abstract and Figure 1 have now been changed in the corrected version of the paper. The caption of Figure 1 has also been updated (page 4 of the paper).

Old Figure 1 and its caption:

Figure 1. Experimental setup at Majadas de Tiétar and La Albuera in the Spain (left panel) and an example of regions of interest (ROIs) in each experimental site (right panel): Grass, Tree, and Ecosystem ROIs, respectively. At each site, an eddy covariance (EC) system was installed at a height of 15 m to measure the fluxes of the whole ecosystem. A near-infrared-enabled camera was installed at 15 m beside the EC system to take pictures half-hourly between 10:00 and 14:30. Three EC towers are in the Majadas de Tiétar (FLUXNET IDs are ES-LM1, ES-LM2, and ES-LMa, respectively) and an EC tower in the La Albuera (FLUX ID: ES-Abr), respectively (not shown). The map of Majadas de Tiétar was provided courtesy of the Spanish Program of Aerial Orthophotography.
