+   Saturation Adjustment Microphysics Model
+----------------------------------
+The saturation adjustment microphysics model is the simplest possible moisture model and only transports the
+water vapor mixing ratio, :math:`q_v`, and the cloud water mixing ration, :math:`q_c`. Evaporation, :math:`q_v \longrightarrow q_c`, and condensation, :math:`q_c \longrightarrow q_v`, are the only relevant mechanisms. The final saturation state, :math:`q_v = q_{vs}(T)` is obtained from Newton-Raphson iterations on the thermal temperature :math:`T`.
