Relationship between the area within the measured and simulated hysteresis loops.

<p>Panel A and B are with respect to ET-<i>T</i>_a and ET-VPD relation, respectively. H_area is calculated from normalized plot (e.g., <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0098857#pone-0098857-g005" target="_blank">Figure 5</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0098857#pone-0098857-g006" target="_blank">Figure 6</a>).
