Current forecasts are available on the ESRL site ( as frame-by-frame animations, but past forecasts are only available on the ESRL FTP site ( Here, as a proof of concept, we extract the daily GIF animations from the FTP site, and make some days of historical forecasts available.

NOTE: ESRL models/algorithms may have changed in the transition from 2017 to 2018.
