MimiIWG FAIRv162 Temperature Trajectories

<h3>1. Introduction</h3><p>These files represent the source code and input files for the temperature trajectories used for the pairing of the MimiIWG integrated assessment model with the MimiFAIRv162 climate model. They serve as inputs for <strong>sensitivity analysis</strong> in Tan, Rennels, and Parthum 2023 "The Social Costs of Hydrofluorocarbons and the Benefits from Their Expedited Phasedown" with replication code for that paper <a href="https://github.com/bryanparthum/schfc-paper">here</a>.&nbsp;</p><p>They are used as automatically downloaded inputs to the <a href="https://github.com/lrennels/MimiIWG_FAIRv162">MimiIWG_FAIRv162</a> repository, a dependency of the paper replication code.</p><p>Please see the publication and repositories for important details about methodology and assumptions <strong>before considering use </strong>and feel free to be in touch with the authors with any further questions or clarifications.</p><h3>2. temp_trajectory_replication.zip</h3><p>This folder holds all code and data to replicate the data outputs. Note that the <i>Manifest.toml </i>and <i>Project.toml</i> files are accessed by the source code to define the Julia environment and should not be modified.</p><h4>data folder (data)</h4><p>Data input files that define the emissions for the IWG EMF-22 scenarios including</p><ul><li>dice_inputs_ch4 - <a href="https://github.com/rffscghg/MimiIWG.jl">https://github.com/rffscghg/MimiIWG.jl</a> repository at path MimiIWG/data/IWG_inputs/DICE/CH4N20emissions_annualversion.xls in CH4annual Tab Units of MtCH4</li><li>dice_inputs_n2o - <a href="https://github.com/rffscghg/MimiIWG.jl">https://github.com/rffscghg/MimiIWG.jl</a> repository at path MimiIWG/data/IWG_inputs/DICE/CH4N20emissions_annualversion.xls in N2Oannual Tab Units of MtN2O</li><li>dice_inputs_land_co2 - <a href="https://github.com/rffscghg/MimiIWG.jl">https://github.com/rffscghg/MimiIWG.jl</a> repository at path MimiIWG/data/IWG_inputs/DICE/SCC_input_EMFscenarios.xls in LandCO2 tab Units of GtC per decade</li><li>dice_inputs_industrial_co2 - <a href="https://github.com/rffscghg/MimiIWG.jl">https://github.com/rffscghg/MimiIWG.jl</a> repository at path MimiIWG/data/IWG_inputs/DICE/SCC_input_EMFscenarios.xls in IndustrialCO2 tab Units of GtC per decade</li></ul><h4>src folder (src)</h4><p>Source code files to produce files in <i>mimiiwg_fairv162_temp_trajectories</i> folder. To produce the output use Julia to run <i>main.jl</i> to produce the output files (~12GB) in an <i>output</i> folder created in the parent directory of <i>main.jl</i>.</p><h3>3. mimiiwg_fairv162_temp_trajectories.zip</h3><p>This folder holds input data files as produced by the src source code above. These are used as inputs for running the MimiIWG-FAIRv162 model.</p><p>There is one file per gas (CO2 and 11 HFCs) - socioeconomic scenario (5 EMF-22 scenarios) making 60 files, plus a key file. All files are in Arrow format for efficiency.</p><p>Each gas-scenario input file has the following specifications:</p><ul><li>2237 sets of temperature trajectories, one for each FAIR constrained parameter set to be used in a Monte Carlo Analysis</li><li>within each set, one baseline temperature trajectory and one trajectory for a pulse of emissions (1GtC or 1 MtHFC) in a given year from 2005 to 2105 in five-year intervals</li><li>units are anomaly from pre-industrial in degrees Celsius</li></ul>
