On the relationship between thermal seeing and observatory design

Environmental effects on the Image Quality (IQ) of the Thirty Meter Telescope (TMT) are estimated by aero-thermal numerical simulations. This study summarizes the state of the art of optical turbulence modeling and presents an update of the ongoing effort to minimize prediction time and computational resources by extrapolating the convergence of TMT’s IQ metric in the spatial resolution limit with quantifiable uncertainty, in order to be able to conduct trade studies and assess IQ sensitivity to various thermal gradient inputs.
