Abstract:
We employ an advanced mesospheric temperature mapper (AMTM) to study the behavior of deep gravity wave propagation into the mesosphere. The measurements take place over the South Island of New Zealand as part of the DEEPWAVE field research campaign based in Christchurch. We investigate waves observed by the AMTM, which measures OH temperatures weighted at an altitude of 87 kilometers, and compare the measurements to forecasts for gravity wave forcing events to examine the relationship between large observed gravity wave events in the MLT region and predicted forcing at lower altitudes.
