چکیده

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 (CMS-Flux) top-down flux inversion system that assimilates column CO2 observations from Greenhouse Gases Observing Satellite (GOSAT) NASA's Observatory 2 (OCO-2). The regional monthly fluxes are readily accessible as tabular files, gridded available in NetCDF format. their evaluated by extensively comparing posterior mole fractions aircraft NOAA marine boundary layer reference sites. We describe characteristics of total, climatological mean, annual seasonal cycles. find total agree atmospheric growth observed surface-observation network within uncertainty. Averaged 2010 2018, tropical regions range close to neutral South America source Africa; these contrast extra-tropics, which sink 2.5±0.3 Gt C/year. satellite-constrained estimates provide unique perspective for understanding carbon dynamics monitoring changes contributions rate. aggregated can be accessed at https://doi.org/10.25966/4v02-c391 (Liu et al.,

Research for VISION 2020

We need good quality information to be able to carry out our eye care programmes in support of VISION 2020, to measure (and improve) our performance, and to advocate for the resources and support we need to succeed. Much of this information can be collected, analysed, and used as part of our daily work, as many of the articles in this issue show. However, many of our questions can only be answe...

The benefits of investing into improved carbon flux monitoring

Operationalizing a Global Carbon Observing and Analysis System (www.geocarbon.net) would provide a sound basis for monitoring actual carbon fluxes and thus getting quantities right when pricing carbon – be it in a cap-and-trade scheme or under a tax regime. However, such monitoring systems are expensive and—especially in times of economic weakness—budgets for science and environmental policy ar...

Biome engineering‐2020

The gut microbiome research is going from a descriptive into an intervention phase. To optimize beneficial microbe-host interaction, we need to understand how to steer the system by modulating the nutrient input with which the system is literally fed (e.g. diets, fibres, prebiotics, human milk oligosaccharides), and we must learn how to modulate the composition of the gut microbiota by adding b...
