(e.g., steps) in the time series due in part to changes in satellite sensors and retrieval algorithms (i.e., TOVS, 1998–2001). A review of their results ( Vinukollu et al. 2011a , their Fig. 6) suggests that SRB, and particularly the combination of SRB radiation components/quality control used herein (see above), yields the most internally consistent (in terms of its components) estimate of R n . 3) AIRS lifting condensation level The AIRS provides high-accuracy retrievals of atmospheric

changes, it is unsurprising that the precipitation changes are different to the evaporation changes ( Figs. 7c,d ). On average, precipitation over land is increased by 0.009 mm day −1 . Similarly to the previous section, we do not see an obvious connection between the difference pattern in the soil moisture–evaporation coupling diagnostic [Ω E (S) − Ω E (W); Fig. 7e ] and the difference pattern in β . It is curious that the increase in eastern Brazil due to the algorithm correction ( Fig. 6e ) is

relations between ET and surface soil moisture ( θ S ) in Fig. 11 . For clarity, these are shown as the piecewise linear regressions of the total ET and daily averaged θ S obtained at the scale of each subbasin for the GAUGES and NLDAS ADJ scenarios. Piecewise regressions of the ET– θ S relation are obtained using a nonlinear optimization algorithm ( Vivoni et al. 2008 ) and describe how water limitations in soils influence losses to the atmosphere ( Rodríguez-Iturbe and Porporato 2004 ). For each
