Short summary
The study compares ocean–atmosphere models, reanalyses, and satellite data for 1991–2020 in the Barents and Kara Seas, where Arctic sea‑ice loss has been greatest. The results evaluate how well these products asses sea ice and ocean temperature. Reanalyses and satellites show strong sea‑ice decline, while models show little or none – only one model shows a near-significant decline in the Barents Sea. Reanalyses also indicate stronger mixed‑layer warming then the models, especially in autumn.
