The document discusses the global carbon budget through the use of three atmospheric inversions from various sources, including the Copernicus Atmospheric Monitoring Service and Jena Carboscope. It highlights the significance of both ocean and land carbon sinks, as well as the variances in sink strength and trends over time. Additionally, the ICOS Carbon Portal is mentioned as a central data repository for users analyzing carbon data.

21. Summary
 Global ocean sink better known than land sink, but still
considerable differences in sink strength and trend.
 Besides tropical land sink, also the ocean and European
land sinks are important to understand the global carbon
budget.
