      abstract     = {Quantifying the eddy diffusion coefficient profile in the
                      mesosphere and lower thermosphere (MLT) is critical to the
                      constituent density distributions in the upper mesosphere
                      and thermosphere. Previous work by Swenson et al. (2018,
                      https://doi.org/10.1016/j.jastp.2018.05.014) estimated the
                      global mean eddy diffusion (kzz) values in the upper
                      mesosphere using atomic oxygen (O), derived from Sounding of
                      the Atmosphere using Broadband Emission Radiometry (SABER)
                      hydroxyl (OH). In this study, vertical eddy diffusive
                      transport velocities of O were determined from continuity of
                      mass in the mesopause region (80–97 km), primarily via the
                      HOx chemistry. Global average constituent climatology from
                      previously deduced SABER ozone (O3) and atomic hydrogen (H)
                      was applied. Furthermore, we extended the global mean eddy
                      transport velocities to new heights (105 km) in the MLT
                      using the newly available global mean Scanning Imaging
                      Absorption Spectrometer for Atmospheric Chartography
                      (SCIAMACHY) data. The combined method of determining O3 loss
                      and O density climatology from SCIAMACHY, as well as an
                      improved global mean background atmosphere from SABER,
                      provides new information for eddy diffusion determination in
                      the MLT. Three prominent results to emerge from this study
                      include (i) global mean kzz profiles between 80 and 105 km
                      derived from MLT constituent climatologies, SABER, and
                      SCIAMACHY global mean O density profiles averaged for
                      approximately one solar cycle, (ii) determination of O eddy
                      diffusion velocities in the MLT consistent between two
                      satellite measurements and the
                      thermosphere‐ionosphere‐mesosphere‐electrodynamics
                      general circulation model, and (iii) resolution of
                      historically large differences between deduced kzz
                      determined from O versus CO2 by analysis of SABER and
                      SCIAMACHY measurements.},
