Brilliant well done Barry. Propagation on 30THz is pretty unknown.
It's the 10um Infrared Window.(8-12um) Propagation of IR in this band (and others) used to be part of my day job. Over 65m there's almost no loss between 25 and 40THz.

Industry standard atmospheric model is Modtran, but it is not cheap.

The older standard Lowtran is available for free.

These guys need to get a hold of some CO2 lasers ;-)

Pretty good going with just modulated hot-plates.
