To assess how this CO<sub>2</sub> sink has evolved over recent decades, various approaches have been used to estimate basin-wide uptake from the irregularly sampled in situ CO<sub>2</sub> observations. Until now, the lack of robust uncertainties associated with observation-based gap-filling methods required to produce these estimates has limited the capacity to validate climate model simulated surface ocean CO<sub>2</sub> concentrations. After robustly quantifying basin-wide and annually varying interpolation uncertainties using both observational and model data, we show that the North Atlantic surface ocean fugacity of CO<sub>2</sub> (<i>f</i>CO<sub>2−ocean</sub>) increased at a significantly slower rate than that simulated by the latest generation of Earth System Models during the period 1992–2014. We further show, with initialized model simulations, that the inability of these models to capture the observed trend in surface <i>f</i>CO<sub>2−ocean</sub> is primarily due to biases in the models' ocean biogeochemistry. Our results imply that current projections may underestimate the contribution of the North Atlantic to mitigating increasing future atmospheric CO<sub>2</sub> concentrations.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Reconciling observation and model trends in North Atlantic surface CO<sub>2</sub>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-05 01:31:28.644664","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2019,"MonPub":null,"DateUpdate":"2022-09-21","DateCreate":"2022-09-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000492490200001","VABBcode":null,"OpenAcc":1,"DOI":"10.1029/2019gb006186"},"refs":null,"anarec":{"AnaID":355607,"PubliDate":2019,"Pagination":"1204-1222","XtraPublOfAnaID":null,"ISBN":null,"Volume":"33","Issue":"10","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45841,"SerRR":"Global Biogeochemical Cycles.
