•SIF outperforms GVI and PRI in tracking GPP.•Temporal aggregation enhances the SIF-GPP relationship.•SIF-GPP relationship varies with water availability.•SIF in combination with SWC can improve GPP estimation. Solar-induced chlorophyll fluorescence (SIF) is strongly physiologically associated with...
