Code and data for "Positive low cloud feedback from increasing surface longwave radiation and parametrized convection in HadGEM3-GC3.1-LL." by Mark J. Webb, Tomoo Ogura and Adrian P. Lock, submitted to JAMES October 2025 The code was developed and run on Google Colab, and uses files saved on google drive. All data needed to make the figures and tables are available in this archive Google Colab Notebook: Webb-Ogura-Lock-figures-and-tables-submitted-Oct-2025.ipynb This produces all of the figures. It also produces the data used in the tables. Running the notebook will reproduce all of these figures, and all of the entries for the LaTeX tables. Directories: map_plots: Contains Figure 1 profile_plots: Contains profile plots point_location_data_lon_lat: Contains numpy pickle files containing data for selected locations used in plots and tables heatmap_plots: Contains heatmap plots used in Figures 2 and 4. ff_time_mean_all_files: Directory for time means of gridded data from the HadGEM3-GC3.1-LL experiments.
