Reanalysis and CMIP6-Derived Annual and Seasonal Means and Trends over the North Atlantic (1940–2024): ERA5, NOAA-20CRv3 and Model Intercomparison Data with GrADS Scripts

This repository contains an index file and five directories comprising software (GrADS scripts) and processed datasets derived from reanalysis products and CMIP6 simulations. The datasets include annual and seasonal means and linear trends over the North Atlantic for the period 1940–2024, based on ERA5, NOAA-20CRv3, and selected CMIP6 model outputs. These materials were used in the preparation of an article on atmospheric circulation responses to multidecadal thermal regime changes in the North Atlantic and it is a first version using outputs from single model realizations (r1). The materials were completed with a second version using ensamble averages of model outputs: https://doi.org/10.5281/zenodo.19815130
