December, 2025 This repository contains the code, model output, and MATLAB scripts required to run the model and reproduce the results presented in Sharoni, Inomura et al., (2026) in the paper entitled "Biochemical remodeling of phytoplankton cell composition under climate change." As a matter of courtesy, we request that people using this code please cite Sharoni, Inomura et al., (2026) In the interest of an "open source" approach, we also request that authors who use the model output please send a copy of the papers to the corresponding author: ssharoni@mit.edu The zip file 'model_output' includes the necessary output files for analysis. Model outputs are in netCDF format: Phase 1: Pre-industrial equilibrium conditions (IGSM_macronol_revised_spinup.nc).Phase 2: Pre-industrial control (IGSM_macromol_revised_run_control.nc). Phase 3: 1860-1990 transient response (IGSM_macromol_revised_run_1860_1990.nc). Phase 4: 1991-2100 transient response (IGSM_macromol_revised_1991_2115.nc). Grid information can be extracted from ‘grid.nc’Ice cover data: DARice.mat The zip file 'figure_scripts' contains the MATLAB scripts needed to reproduce the main figures presented in the paper. To run the model, download the code and input directories, and obtain the model source code from the official MITgcm GitHub repository.------------------------------------------------------------------------------ Contact Information: Shlomit Sharoni, PhD E-mail: ssharoni@mit.edu
