Fig. 4From: The spatial variability of actual evapotranspiration across the Amazon River Basin based on remote sensing products validated with flux towersScatter diagram of accumulated ET measured by flux towers plotted against ET-Amazon values for a 2-month or longer integration period, for each of the three ET methods: (1) direct measurements (a), (2) the residual of energy balance (b), and (3) the Bowen ratio (c). The one-to-one line (dashed) and the trend line (solid) are also shownBack to article page
