Methodology
  • WACCM-X Atomic oxygen densities on pressure grid are interpolated to altitude grid and used in Global Ionosphere Thermosphere Model (GITM). This simulation is then compared with GITM driven with MSIS as the lower boundary.

  • All neutral densities, temperature and winds at the lower boundary are kept the same between the two simulations apart from O densities. GITM w/ MSIS simulation uses O from MSIS where GITM w/ WACCM-X uses O from WACCM-X.

  • WACCM-X lower boundary files on altitude grid are in the folder 'waccm_lower_boundary_files' ; GITM w/ MSIS simulations are in the folder - run_msis_Jan_2010 and run_msis_June_2010; GITM w/MSIS diagnostic files are in the folder - run_msis_Jan_2010_USR_files; GITM w/ WACCM simulations are in the folder - run_waccm_Jan_2010 and run_waccm_June_2010; GITM w/ WACCM diagnostic files are in the folder - run_waccm_Jan_2010_USR_files.
Description
  • This research aims to understand the importance of lower thermospheric atomic oxygen on the upper thermosphere. O number densities between 95-100 km from WACCM-X are much closer to the observations from SABER instrument on TIMED satellite as compared to those from MSIS. We show in this study that the correction of the lower boundary atomic oxygen yields better agreement between GITM and GUVI O/N2 in the upper thermosphere .
