Thermodynamic data required for AGNI and other atmosphere modules in the PROTEUS framework. Data are compiled into NetCDF files (one file per species) and zipped into `gases.zip`. These files are provided with BLAKE2b checksums. Compiled data heat capacity as a function of temperature latent heat as a function of temperature equation of state tables (density as a function of temperature and pressure) where available molar mass saturation curves where available Sources NIST Webbook - https://webbook.nist.gov/ JANAF Tables (Chase et al., 1985) - https://janaf.nist.gov/ IAPWS95, Wagner & Pruß (2002) - https://pubs.aip.org/aip/jpr/article/31/2/387/241937/The-IAPWS-Formulation-1995-for-the-Thermodynamic Feistel & Wagner (2006) - https://www.sciencedirect.com/science/article/pii/S0016703706020461 Coker (2007), Appendix C - https://doi.org/10.1016/B978-0-7506-7766-0.X5000-3 AQUA water equation of state - https://www.aanda.org/articles/aa/abs/2020/11/aa38367-20/aa38367-20.html CMS19 hydrogen equation of state - https://iopscience.iop.org/article/10.3847/1538-4357/aaf99f Van der Waals coefficients - https://en.wikipedia.org/wiki/Van_der_Waals_constants_(data_page) Others documented in code The compiled NetCDF files are generated using the ThermoTools pipeline on GitHub: https://github.com/nichollsh/ThermoTools EOS data for hydrogen and water are also archived in this Zenodo record.
