We employ two 2-dimensional, nonlinear, time-dependent numerical models, Multiple Airglow Chemistry Dynamics (MACD) and OH Chemistry Dynamics (OHCD), to investigate gravity wave induced airglow variations in the Mesosphere and Lower Thermosphere (MLT) region. Our work is focused on the OH airglow, O2(0,1) atmospheric band, and O(1S) greenline airglow emissions. The atmospheric reference model has been upgraded from MSIS-90 to NRLMSISE-00. One of the reasons for upgrading to NRLMSISE-00 is that the model contains recent data on temperature and molecular oxygen number density, O2. Also, the techniques used to process incoherent scatter radar data have experienced significant changes since 1990, which leads to superior quality of the inferred ionospheric properties. We will report the changes on minor and major gas densities, as well as the temperature retrieved from both reference models, and investigate how this affects the aforementioned airglow emissions.
