Analysis and plotting code for paper by R.D. Russotto and T.P. Ackerman in Atmos. Chem. Phys. special issue on the Geoengineering Model Intercomparison Project. DOI for paper: 10.5194/acp-2017-823 Python code was written by Rick Russotto. The APRP.py and moistEBM.py modules were based in part on Matlab scripts provided by Yen-Ting Hwang. If you use any of this code, please acknowledge where it came from. Python scripts were run using Python 2.7.9. Versions of packages used: -Matplotlib 1.5.1 -NumPy 1.8.2 -NetCDF4 1.1.0 Which scripts made which plots: Figures 1, 2, 3, 4a: v2_meridionalEnergyTransport.py Figure 4b: itczShiftFigureWithCSIRO.py Figures 5, 6, 7, 8: runEBM.py Table 1: temperatureGlobalMean.py findCSIRO_reduction.py (for percentage solar constant reduction in CSIRO model, not previously published) Table A1: errorAnalysisEnergyTransport.py Table B1: EBM_tuneAB.py Other scripts and modules that the above scripts depend on: APRP.py correctCESM_rlut.py find_rlut_correction.py geomipFunctions.py moistEBM.py scriptUsingAPRPonGeoMIP.py These scripts are also available at the URL: https://atmos.washington.edu/articles/GeoMIP_EnergyTransport_PolarAmplification_ITCZ/ The APRP.py module can also be found at https://github.com/rdrussotto/pyAPRP, with further documentation.
