Fig. 2

a Summer interannual variability (IAV), represented by the standard deviation around the long-term (2000–2016) GPP mean (gCm−2) pooled for forest, grassland, and savanna/shrubland sites. Bars represent: observed (brown), DryFlux (dark gray), MODIS (green), and FLUXCOM GPP (teal). b Differences in interannual GPP (in gCm−2 day−1) across all sites. Lines represent: observed (brown), DryFlux (dark gray), MODIS (green), and FLUXCOM GPP (teal). Differences in estimated annual GPP (gCm−2 year−1) at 0.5° resolution between 2011 and 2015 in (c) the DryFlux and (d) FLUXCOM models. Southwest flux tower sites used in DryFlux model building and testing are symbolized as crosses on (c).
