We characterise the carbon sink in terms of mean, seasonal cycle, trends and storage.

Does any here have an idea why the #RECCAP2 (and GCB) hindcast ocean models accumulate less heat than the observation-based estimates suggest?
The underestimation of the transient warming is a factor of 2 to 3. Similarly, ocean deoxygenation due to ocean warming is also underestimated by a factor of 3 to 5 (www.nature.com/articles/s41...). It is hence also likely that natural carbon loss due to ocean warming is highly underestimated.

Doney et al. revisited the biological carbon pump and found that the model–based export production fell at the lower end of observational estimates, suggesting that models underestimate the biological drawdown and air-sea fluxes of CO₂ in high productivity regions.

During #RECCAP2, we have found a few reasons that show why ocean models in hindcast mode underestimate the ocean carbon sink, some are due to the setup and some due to physics and biogeochemistry (agupubs.onlinelibrary.wiley.com/doi/epdf/10....).

We provided recommendations of how to improve model estimates but implementing those improvements will take time and needs to be carefully done. Until then, the GOBM estimates remain useful but unfortunately also imperfect to estimate the current ocean carbon sink.
