> They are used with little modification to correctly model climate of Mars, Venus, tidal locked exoplanet and previous historical eras on Earth. Never heard that claim. Could you back it up? Side note. I did a calculation of PV=nRT on Venus which has a 96.5% (965000PPM) CO2 atmospheric concentration. Assuming RT is close to equal on Venus & Earth, P~T. Venus has a surface temp/pressure of 7.96 K/bar vs 287.15 K/bar on Earth. If Venus had a runaway greenhouse effect, the K/bar on Venus should be significantly higher than on Earth. Would love more feedback & critique on this calculation, particularly a relevant PVT diagram for CO2. https://docs.google.com/spreadsheets/d/1mn4yuh2TUKWeMtMpZkDN... ---- Heres a PVT phase diagram for CO2 but hopefully theres better ones wrt Venus. Note that theres a bend in the liquid/gas border. 1 to 10 bar has a lower increase of K/bar than for the 10 to 90 bar region. https://www.researchgate.net/figure/A-phase-diagram-for-CO2_... |
