Impact of droughts during the autumn 2017 (Aut17), spring 2019 (Spr19) and the heatwave of summer 2018 (HW18, Sum18) on carbon fluxes (NEE, GPP, Reco) compared to the average of each season across all years (Aut, HW, Sum, Spr). (Values are cumulated for the period 1 October–30 November 2017 (Aut17), 2 August 2018 (HW18), 1 June–30 September 2018 (Sum18) and 1 March–31 May 2019 (Spr19) ± uncertainty. The same periods were selected for the seasonal averages but for all years. For a graphical representation of the values normalized to g C m−2 d−1 please see the electronic supplementary material, figure S7.)
