| Summary: | Massachusetts Institute of Technology general circulation model (MITgcm, https://github.com/MITgcm/MITgcm ) model output used in study 'Decadal variability of ice-shelf melt in the Amundsen Sea driven by freshwater fluxes' by Michael Haigh and Paul R. Holland (2024), Geophysical Research Letters. Also provided are Python scripts for processing the data. The model uses a 1/10 degree resolution, 50 vertical levels configuration of the Amundsen Sea. The domain spans 140°W to 80°W and 76°S to 62°S. The model includes ocean, ice-shelf and sea-ice thermodynamics. The model is forced by ERA5 atmospheric data during 1979-2019. 6 NetCDF files are included in the dataset: state2D.nc stateExf.nc stateRho.nc stateTheta.nc stateUvel.nc stateVvel.nc Also provided is a zip file containing: (1) *.data and *.meta files of model grid data, (2) Python scripts for processing model output and (3) *.npy files which are outputs of PROCESS_DATA.py and can be plotted using PLOT_DATA.py. The provided Python scripts produce figures for 'Haigh & Holland (2024), Decadal variability of ice-shelf melt in the Amundsen Sea driven by freshwater fluxes.' Sea README.md for details. This research was funded by the NERC project ``Drivers of Oceanic Change in the Amundsen Sea'', NE/T012803/1.
