Table 1.
Anomalies for the 2018 drought (July–August–September) with respect to the climatological average from 2013 to 2017. GPP, TER and NEE are calculated from monthly mean values and are in the units of gC m2 day−1. 1σ values result from averaging over multiple sites. Note that for the croplands, the crop rotation scheme is not taken into account.
