Figure 4 . As in Fig. 2, but for the latent heat flux. The observational data are from FLUXNET-MTE (Jung et al., 2009, 2010). The FLUXNET-MTE data are from the FLUXNET network of eddy covariance towers, which have been upscaled to monthly evapotranspiration on a 0.5° × 0.5° grid (Jung et al. 2010) using the MTE approach described by Jung et al. (2009) (1982–2004 average).
