Source code, configuration, and namelist files for Morrison et al. (2026), BAMS

This file describes all files contained in this repository. These include the CM1-SDM source code, namelist, and forcing files and analysis/plotting software for Morrison et al. 2026, BAMS: A virtual cloud physics laboratory. 10.5281/zenodo.17664087 CM1-SDM files: DNS case CM1 namelist file for Pi chamber runs: namelist.input_dns SDM source code files and modified CM1r21.0 files for coupling with SDM are contained in the tar file: CM1-SDM-DNS-ASD.tar The original CM1 r21.0 code (released 20 April 2022) may be obtained from: https://www2.mmm.ucar.edu/people/bryan/cm1/downloadcode.html After unzipping and un-tarring the original CM1 r21.0 code, the SDM and modified CM1 source code files from CM1-SDM-ASD.tar can be added in the ./src/ directory of the original CM1 code. This will overwrite a handful of original CM1 files with the modified files, as well as add the SDM source code riles. This will generate the “complete” CM1-SDM source code for compiling and running the cm1.exe executable. Cumulus congestus case SDM source code files and modified CM1r21.0 files for coupling with SDM and forcing files are contained in the tar file: CM1-SDM-ASD.tar The original CM1 r21.0 code (released 20 April 2022) may be obtained from: https://www2.mmm.ucar.edu/people/bryan/cm1/downloadcode.html After unzipping and un-tarring the original CM1 r21.0 code, the SDM and modified CM1 source code files from CM1-SDM-ASD.tar can be added in the ./src/ directory of the original CM1 code. This will overwrite a handful of original CM1 files with the modified files, as well as add the SDM source code riles. This will generate the “complete” CM1-SDM source code for compiling and running the cm1.exe executable. The following forcing files contained within the above tar file should be added to the ./run/ directly of CM1: aerosol_profile_factor.dat TurbEnh_interp.dat input_sounding CM1 namelist file for cumulus congestus case: namelist.input_CuC General information Additional information about compiling and running CM1 can be found in README files that come with the original CM1r21.0 code as well as documentation here: https://www2.mmm.ucar.edu/people/bryan/cm1/ The SDM code used in our simulations was developed from the original SDM code available here: https://github.com/Shima-Lab/SCALE-SDM_BOMEX_Sato2018 (Sato 2018) Sato, Y., 2018: SCALE-SDM_BOMEX_Sato2018, v0.1, Github, https://github.com/ShimaLab/SCALE-SDM_BOMEX_Sato2018.
