Dataset for "Decreased northern hemisphere precipitation from consecutive CO2 doublings is associated with significant AMOC weakening"

Zhang, X., Waugh, D. W., Mitevski, I., Orbe, C., & Polvani, L. M. (2024). Decreased northern hemisphere precipitation from consecutive CO2 doublings is associated with significant AMOC weakening. Environmental Research: Climate. https://doi.org/10.1088/2752-5295/ad929c

We analyzed surface temperature (TS), precipitation (PR), and the Atlantic meridional overturning circulation (AMOC) streamfunction from multiple coupled climate models simulations across different abrupt CO2 forcing experiments. The original data are downloaded from the CMIP6 archive, the LongrunMIP archive (https://www.longrunmip.org/), and from a previous study by Mitevski et al. (2021, doi: 10.1029/2020GL090861). Data are post processed using Python code and are saved in NetCDF format.

Files and variables:

File: AMOC.zip

Description: This folder includes NetCDF files of the Atlantic meridional overturning circulation (AMOC) streamfunction (in Sv) time series from all models. File names indicate model names.

File: TS_PR.zip

Description: This folder includes NetCDF files of spatially varying (in latitude and longitude) surface temperature (TS, in K) and precipitation (PR, in kg s-1 m-2) time series from all models. File names indicate model names.

The data can be viewed using Python packages Xarray, Matplotlib, and Cartopy, as well as NCO.
