# ACE2-EAMv3

Ai2 Climate Emulator (ACE) is a family of models designed to simulate atmospheric variability from the time scale of days to centuries.

**Disclaimer: ACE models are research tools and should not be used for operational climate predictions.**

ACE2-EAMv3 is trained on output from the E3SMv3's atmosphere model (i.e. EAMv3) forced with historical sea surface temperature (AMIP) from 1970-2020.

**Warning: this model does not work with the current ACE release, a newer release is coming soon**
