Data and code supporting publication Thomas &amp; Yelland 2023 "Terrestrial Effects of Nearby Supernovae: Updated Modeling" Paper citation: Brian C. Thomas and Alexander M. Yelland 2023 ApJ 950 41<br> DOI: 10.3847/1538-4357/accf8a Contents of this repository: * Data files (in netCDF format) generated by GSFC 2D atmospheric chemistry-dynamics model, for cases described in referenced paper. * Code "SNCR_Flux_and_Ionization.m" used to calculate supernova cosmic ray proton flux and resulting terrestrial atmospheric ionization rates, for cases described in the referenced paper. Also includes necessary input data files. * Data files (SNCR_flux.zip and SNCR_ionization.zip) generated by "SNCR_Flux_and_Ionization.m" code, as presented, discussed, and used in referenced paper. * Code "SNCR_muon-flux.m" used to calculate terrestrial surface-level cosmic ray secondary muon flux in the cases described in referenced paper, as well as biological damage values due to that flux. Also includes necessary input data files. Code files were created and run in Octave, and should run on Matlab as well.
