Changes in GPP (PgC) during the El Niño period in comparison with the baseline years 2007–2014. Values are derived for the whole Amazon basin and by the region. Results from the coupled SiBCASA–PCR-GLOBWB simulations are compared with the default SiBCASA run, which uses ERA-Interim meteorology and no coupling to the PCR-GLOBWB soil moisture. Ranges in parentheses result from different rooting depths in the model, as discussed in the main text.
