                      organic aerosol (SOA) phase state and mixing times within
                      SOA is needed to predict the impact of SOA on air quality,
                      climate, and atmospheric chemistry; nevertheless, such
                      information is rare. In this study, we developed
                      parameterizations for viscosity as a function of relative
                      humidity (RH) and temperature based on room-temperature
                      viscosity data for simulated pine tree SOA and toluene SOA.
                      The viscosity parameterizations were then used together with
                      tropospheric RH and temperature fields to predict the SOA
                      phase state and mixing times of water and organic molecules
                      within SOA in the troposphere for 200 nm particles. Based on
                      our results, the glassy state can often occur, and the
                      mixing times of water can often exceed 1 h within SOA at
                      altitudes >6 km. Furthermore, the mixing times of organic
                      molecules within SOA can often exceed 1 h throughout most of
                      the free troposphere (i.e., ≳1 km in altitude). In most of
                      the planetary boundary layer (i.e., ≲1 km in altitude),
                      the glassy state is not important, and the mixing times of
                      water and organic molecules are less than 1 h. Our results
                      are qualitatively consistent with the results from Shiraiwa
                      et al. (Nat. Commun., 2017), although there are quantitative
                      differences. Additional studies are needed to better
                      understand the reasons for these differences.},
