Climate Reanalyzer: Visualizing Daily Global Temperatures

2025-01-21

The Climate Reanalyzer website, from the University of Maine's Climate Change Institute, provides interactive visualizations of daily global temperatures based on ECMWF ERA5 reanalysis data. The site offers interactive charts and maps showing daily mean surface air temperature from 1940 to the present, allowing users to select different regions for analysis. Data updates are delayed by 6-7 days, and users are cautioned to treat extreme temperatures estimated by ERA5 with care. The site also provides access to other climate data, such as sea surface temperature and sea ice extent.
