  1. aThe uncertainties refer to those of annual mean volume flux in each period and in 2018. They are calculated from uncertainties of monthly mean volume flux shown in Fig. 3c by taking propagation of error into account. The standard deviations also refer to those of the annual mean volume flux. See description in method section.
