Here we conduct a series of large ensemble simulations (300 members each) to explore the robustness of the stratospheric response to Arctic sea-ice loss. We follow the new PAMIP protocol using the SC-WACCM4 and E3SM models.

• Scripts/: Main Python scripts/functions used in data analysis and plotting
• requirements.txt: List of environments and modules associated with the most recent version of this project. A Python Anaconda3 Distribution was used for our analysis. All AGCM experiments were processed through resources on CISL's Cheyenne supercomputer. Tools including NCL, CDO, and NCO were also used for initial data manipulation.
