Climate Reanalyzer is produced by the Climate Change Institute at the University of Maine, with support from the National Science Foundation and private foundations. It visualises existing, publicly available datasets and models rather than producing its own: daily sea surface temperature from NOAA OISST v2.1, daily surface air temperature from the ECMWF ERA5 reanalysis, daily sea ice extent, and monthly US temperature and precipitation.
Each daily chart is backed by a JSON file of day-of-year values for every year of the record, plus the 1991–2020 mean and a preliminary tail. That is what the Vitals page here reads for global and Niño 3.4 sea surface temperature and for global 2 m air temperature.
