MITgcm simulations to study ENSO in warmer climates

This data is the semi-processed data used to study ENSO and warming in Tuckman, Understanding ENSO Weakening in Warmer Climates, 2025. The goal of the simulations is to understand how ENSO events differ in warmer climates. This dataset includes five simplified MITgcm simulations with different CO_2 longwave absorption efficiencies and therefore temperatures. Folders for each simulation included here contain ocean velocities and temperatures, as well as atmospheric surface fluxes and other relevant quantities., , , # MITgcm simulations to study ENSO in warmer climates

## Description of the data and file structure

This is the relevant model data from MITgcm simulations for the paper \"Understanding ENSO Weakening in Warmer Climates\" (https://doi.org/10.1029/2024GL113124). The code is available here: \"[verification_other/cpl_gray+swamp+ocn at master · MITgcm/verification_other · GitHub\"](https://github.com/MITgcm/verification_other/tree/master/cpl_gray%2Bswamp%2Bocn). The goal of the simulations and data included here was to understand how ENSO events differ in warmer climates. The simulations were warmed by changing the longwave absorption efficiency of CO_2 (ir_tau_co2) in the code, and run for at least 750 years so they would come to a quasi-steady-state. The data stored here is from after this equilibriation period.
