Liu et al. as discussed by the authors presented a global and regionally resolved terrestrial net-biosphere exchange (NBE) dataset with corresponding uncertainties between 2010-2018: Carbon Monitoring System Flux Net Biosphere Exchange 2020 (CMS-Flux NBE 2020).Abstract:
. Here we present a global and regionally resolved terrestrial net
biosphere exchange (NBE) dataset with corresponding uncertainties between
2010–2018: Carbon Monitoring System Flux Net Biosphere Exchange 2020 (CMS-Flux NBE 2020). It is estimated using the NASA Carbon
Monitoring System Flux (CMS-Flux) top-down flux inversion system that
assimilates column CO 2 observations from the Greenhouse Gases Observing Satellite (GOSAT) and NASA's Observing Carbon Observatory 2 (OCO-2). The
regional monthly fluxes are readily accessible as tabular files, and the
gridded fluxes are available in NetCDF format. The fluxes and their
uncertainties are evaluated by extensively comparing the posterior CO 2
mole fractions with CO 2 observations from aircraft and the NOAA
marine boundary layer reference sites. We describe the characteristics of
the dataset as the global total, regional climatological mean, and regional
annual fluxes and seasonal cycles. We find that the global total fluxes of
the dataset agree with atmospheric CO 2 growth observed by the
surface-observation network within uncertainty. Averaged between 2010 and
2018, the tropical regions range from close to neutral in tropical South
America to a net source in Africa; these contrast with the extra-tropics,
which are a net sink of 2.5±0.3 Gt C/year. The
regional satellite-constrained NBE estimates provide a unique perspective
for understanding the terrestrial biosphere carbon dynamics and monitoring
changes in regional contributions to the changes of atmospheric CO 2
growth rate. The gridded and regional aggregated dataset can be accessed at

TL;DR: In this paper, the authors developed spatially explicit estimates of carbon stock changes of live woody biomass from 2000 to 2019 using measurements from ground, air, and space, and showed that live biomass has removed 4.9 to 5.5 PgC year−1 from the atmosphere, offsetting 4.6 ± 0.1 pgC of gross emissions from disturbances and adding substantially (0.23 to 0.88 pgc year− 1) to the global carbon stocks.

TL;DR: It is found that the global carbon sink anomaly was driven by growth of semi-arid vegetation in the Southern Hemisphere, with almost 60 per cent of carbon uptake attributed to Australian ecosystems, where prevalent La Niña conditions caused up to six consecutive seasons of increased precipitation.
