► Flooded and aerobic fields can become weaker or stronger sinks of CO2 during ENSO. ► GPP of flooded field was more sensitive to increase in VPD than non-flooded field. ► The GPP in flooded rice was substantially larger than in aerobic rice. ► Flooded rice field had lower Re than non-flooded field...
