| ju26e_v1 | Identifying and correcting the World War 2 warm anomaly in sea surface temperature measurements | Most foregoing estimates of historical sea surface temperature (SST) feature warmer global-average SSTs during World War 2 well in excess of climate-model predictions. This warm anomaly, referred to as the WW2WA, was hypothesized to arise from incomplete corrections of biases associated with rapid changes in measurement instruments and protocols. Using linear mixed-effects methods we confirm highly significant offsets among specific groups of bucket and engine-room-intake SST measurements that, upon correction, reduce the WW2WA by 0.26°C (95% c.i. 0.15 to 0.38°C). Furthermore, SST measurements during WW2 coming from buckets are reportedly warmer at night than day, and controlling for this evident bias reduces the WW2WA by another 0.05°C (0.02 to 0.08°C). Adjusted SSTs give a more stable and smoothly evolving record of historical warming with a WW2WA of 0.09°C (-0.01 to 0.18°C) that is consistent with internal variability in climate models. | 2020-08-20T13:30:02.474650 | 2021-02-08T21:35:21.019437 | 2020-08-20T19:15:05.982366 | eartharxiv | 0 | withdrawn | 1 | 1 | https://doi.org/10.31223/osf.io/ju26e | GNU Lesser General Public License (LGPL) 2.1 | Bias; Correction; Model-data discrepancy; Sea surface temperature; World War II | ["Bias", "Correction", "Model-data discrepancy", "Sea surface temperature", "World War II"] | Duo CHAN; Peter Huybers | [{"id": "qvzue", "name": "Duo CHAN", "index": 0, "orcid": "0000-0002-8573-5115", "bibliographic": true}, {"id": "zh72a", "name": "Peter Huybers", "index": 1, "orcid": "0000-0002-3734-8145", "bibliographic": true}] | Duo CHAN | Physical Sciences and Mathematics; Oceanography and Atmospheric Sciences and Meteorology; Oceanography; Climate | [{"id": "59ea64a954be8111216c1395", "text": "Physical Sciences and Mathematics"}, {"id": "59ea64a954be8111216c13b9", "text": "Oceanography and Atmospheric Sciences and Meteorology"}, {"id": "59ea64a954be8111216c13bd", "text": "Oceanography"}, {"id": "59ea64a954be8111216c13be", "text": "Climate"}] | 0 | no | no | [] | 2025-04-09T20:04:02.576025 |
