yes, collision broadening is included

Cool, thanks for sharing!

🧪 I'm a fan of this way of interacting with vibrational spectra. I did this on my blog a while ago: nanoscale.blogspot.com/2015/06/what...

Thanks! Our simulations aren't quite in the same regime as Venus, but we separately used the model to recreate Venus's temperature profile and it did pretty well. We found it was right on the edge of convective instability in Venus's lower atmosphere, interestingly.

On a related note, we found that convective shutdown by the same mechanism can drastically shorten primordial magma ocean freeze-out times, though with enough irradiation there can be persistent magma oceans despite convective shutdown. arxiv.org/abs/2412.11987

I mean yeah pretty worried, of course : ). The problem with the continuum in the visible is that we need really long path lengths and/or sensitive measurements, which means $$$ for experiments. Maybe ab initio can help, although H2O is a tough molecule to simulate.

The resurfacing is very episodic but it’d still be pretty bad in a period of peak activity. Then in the good times you’d have slimy microbial mats as far as the eye could see. No skyr or harðfiskur, unfortunately.

It's a fascinating question. Global temperature matters a lot, but so do other factors like total area and latitude (equatorial LIPs weather fastest due to higher rainfall rates). If e.g. Brazil was turned into a LIP today, that could well trigger a Snowball.
