description: This archive contains supporting information, code, and data files associated with the Cloud-Feedback Model Intercomparison Project simulations from the Community Earth System Model (Version 2; CESM2). All of the simulations are publicly available as part of the CMIP6 archive, and can be found using the Earth System Grid Federation (e.g., at the LLNL node). This archive consists of a set of zipped tar files and documentation. The files are described next. First is `case_directories.tgz` containing a directory of subdirectories, one for each simulation. These represent an archive snapshot of the CESM case directory for each simulation; they include final namelists and scripts used to build and run the case along with informational files, log files, and the software environment description. Second is `user_bc_files.tgz,` which contains boundary conditions files for some cases. Third are the initial conditions files needed for select cases, broken into `.tgz` files for each case, as detailed below. The file `user_namelist_modifications.tgz` contains namelist and source code modifications. The file `scripts_cylc.tgz` contains information about the Cylc workflow for each case. The file `input_support_files.tgz` contains files and code to construct the specialized boundary conditions for some cases. Finally a pdf file called `CFMIP_CESM2_case_notes.pdf` contains detailed notes for each of the Tier 2 simulations. Additional details for these files: <strong>case_directories</strong>: An archive snapshot of the CESM2 case directories for all 24 CFMIP simulations. Case directories include simulation configuration and software environment settings. All simulations were run on NCAR's Cheyenne system. The 24 simulation names and case names are organized into subdirectories named for the case name as follows: <strong>a4SST</strong> : f.e21.F1850_BGC.f09_f09_mg17.CFMIP-a4SST.001 <strong>a4SSTice</strong> : f.e21.F1850_BGC.f09_f09_mg17.CFMIP-a4SSTice.001 <strong>a4SSTice-4xCO2</strong> : f.e21.F1850_BGC.f09_f09_mg17.CFMIP-a4SSTice-4xCO2.001 <strong>abrupt-0p5xCO2</strong> : b.e21.BCO2x0p5cmip6.f09_g17.CMIP6-abrupt0p5xCO2.001 <strong>abrupt-2xCO2</strong> : b.e21.BCO2x2cmip6.f09_g17.CMIP6-abrupt2xCO2.001 <strong>abrupt-solm4p</strong> : b.e21.B1850cmip6.f09_g17.CMIP6-abrupt-solm4p.001 <strong>abrupt-solp4p</strong> : b.e21.B1850cmip6.f09_g17.CMIP6-abrupt-solp4p.001 <strong>amip-4xCO2</strong> : f.e21.FHIST_BGC.f09_f09_mg17.CFMIP-amip-4xCO2.001 <strong>amip-a4SST-4xCO2</strong> : f.e21.FHIST_BGC.f09_f09_mg17.CFMIP-amip-a4SST-4xCO2.001 <strong>amip-future4K</strong> : f.e21.FHIST_BGC.f09_f09_mg17.CFMIP-amip-future4K.001 <strong>amip-lwoff </strong>: f.e21.FHIST_BGC.f09_f09_mg17.CFMIP-amip-lwoff.001 <strong>amip-m4K</strong> : f.e21.FHIST_BGC.f09_f09_mg17.CFMIP-amip-m4k.001 <strong>amip-p4K </strong>: f.e21.FHIST_BGC.f09_f09_mg17.CFMIP-amip-p4k.001 <strong>amip-p4K-lwoff</strong> : f.e21.FHIST_BGC.f09_f09_mg17.CFMIP-amip-p4k-lwoff.001 <strong>amip-piForcing</strong> : f.e21.F1850_BGC.f09_f09_mg17.CFMIP-amip-piForcing.001 <strong>aqua-4xCO2</strong> : f.e21.QPC6.f09_f09_mg17.CFMIP-aqua-4xCO2.001 <strong>aqua-control</strong> : f.e21.QPC6.f09_f09_mg17.CFMIP-aqua-control.001 <strong>aqua-control-lwoff </strong>: f.e21.QPC6.f09_f09_mg17.CFMIP-aqua-control-lwoff.001 <strong>aqua-p4K </strong>: f.e21.QPC6.f09_f09_mg17.CFMIP-aqua-p4K.001 <strong>aqua-p4K-lwoff</strong> : f.e21.QPC6.f09_f09_mg17.CFMIP-aqua-p4k-lwoff.001 <strong>piSST </strong>: f.e21.F1850_BGC.f09_f09_mg17.CFMIP-piSST.001 <strong>piSST-4xCO2</strong> : f.e21.F1850_BGC.f09_f09_mg17.CFMIP-piSST-4xCO2.001 <strong>piSST-4xCO2-rad</strong> : f.e21.F1850_BGC.f09_f09_mg17.CFMIP-piSST-4xCO2-rad.001 <strong>piSST-pxK</strong> : f.e21.F1850_BGC.f09_f09_mg17.CFMIP-piSST-pxK.001 Note case names are meant to follow standard CESM conventions. <strong>user_bc_files</strong>: Boundary conditions files needed by certain simulations. Organized into subdirectories by case name. <strong>Initialization files</strong>: Component initialization files needed by certain simulations. Due to their larger size, these are provided as separate files by case name prepended by `INIT_`.
