CESM2 Mediterranean Sea Pacemaker Ensemble

These NetCDF files correspond to the monthly outputs of the model study, which aims to produce a Mediterranean Sea Pacemaker Ensemble for the period 1980–2014, to investigate the impacts of the Mediterranean Sea on regional and global climate.

Model simulations are completed using the fully-coupled Community Earth System Model version 2.1.3 (CESM2) (the CESM2.1.3 code is available on GitHub).

Detailed experimental design and methodology are explained in the scientific paper titled "Climatic Impacts of a Warmer Mediterranean Sea Simulated by the Fully-Coupled Community Earth System Model version 2 (CESM2)" authored by Emir Toker, Mehmet Ilicak, Gokhan Danabasoglu, and Omer Lutfi Sen. The figures presented in the paper are illustrated using the model output uploaded to this cloud.

For the naming conventions of CESM2 model output, please follow this link: Naming Conventions.

In the model output, we have three groups:

Control

Mediterranean Pacemaker

Mediterranean Pacemaker Plus3.

Both Mediterranean Pacemaker experiments were nudged with observational gridded Sea Surface Temperature (SST) data from ERSST (Huang et al., 2017) and OISST (Huang et al., 2021).
