There's a few:
NOAA's GHCN: Global Historical Climatology Network, Its coverage includes data going back several centuries, with the earliest records starting around 1750.
HadCRUIT (Hadley Centre/Climatic Research Unit Temperature). Has marine (ship-borne and buoy) and terrestrial (land-based stations) sources.
NASA's GISS Surface Temperature Analysis has records from the 1880s.
As for calibration, I believe some places routinely calibrated their mercury tstats. But since that was a potential issue, we started using indirect measurements (eg: what I mentioned) to confirm certain climate trends.
- pcdoodle 2y agoNOAA's GHCN web portal has "Add to Cart" next to the records. Are there any free climate data regarding ocean temps with a paper trail of the measurements and any "updates" that might have been done over the years?
- abenga 2y agoHere's a global gridded data set: https://cds.climate.copernicus.eu/cdsapp#!/dataset/insitu-gridded-observations-global-and-regional?tab=overview https://cds.climate.copernicus.eu/cdsapp#!/dataset/insitu-gr... from which you can easily extract ocean temperature data from 1750 onwards, including links to documentation of input data sets: https://datastore.copernicus-climate.eu/documents/insitu-gridded-observations-global-and-regional/C3S_D62.3.5.1.v1_202110_Documentation_observation_data_v1.pdf https://datastore.copernicus-climate.eu/documents/insitu-gri..., in case you were asking in good faith.
