Purpose

ATMOS_MOD holds one number, HRAS $= \mathrm{HRA}(\tfrac23)$, the $T(\tau)$ relation at $\tau = 2/3$. It replaces COMMON/ATMOS/ (MHP via Claude, 10/14/26).

Who sets it, who reads it. SETUPS sets it once, from HRA; ENVINT and QATM use $\log T = \log T_\mathrm{eff} + \mathrm{HRA}(\tau) - \texttt{HRAS}$, so that $T = T_\mathrm{eff}$ at $\tau = 2/3$.
