| Zusammenfassung |
| We present a new detailed non-LTE model of OH(v) for the nighttime mesosphere/lower
thermosphere. The model accounts for chemical production of vibrationally excited OH and
for various vibrational-vibrational (VV) and vibrational-translational (VT) energy exchanges
with main atmospheric constituents. The new feature was added to account for the "indirect"
vibrational-electronic (VE) mechanism OH(v)→O(1D)→N2(v) of the OH vibrational energy
transfer to N2, recently suggested by Sharma et al. [2015] and confirmed through laboratory
studies by Kalogerakis et al. [2016]. We study the impact of this mechanism on the OH(v)
populations and emissions in the two SABER channels at 1.6 and 2.0 μm. We also discuss the
implications this mechanism will have on the retrieval of OH and O densities, as well as its
effects on the nighttime CO2 density retrievals from the SABER 4.3 μm channel. |
