Figure 1 .
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.
