Semi-annual reports on mesopheric dynamics and chemistry from SME data. [Darrell F Strobel; United States. National Aeronautics and Space Administration.]. Our measurements are the first to report a long period seasonal variation at two upper mesospheric altitudes simultaneously over the Indian sector.
Our observations reveal the presence of a dominant semi-annual oscillation (∼6 months periodicity) together with a shorter period (∼ months periodicity) oscillation in both OH and O 2 by: 4.
These data provide new evidence in support of a semi-annual-oscillation in mesospheric temperature (and airglow emission intensities) and help quantify its seasonal characteristics.
View Show abstract. Further, using OH(6,2) and O 2 mesospheric temperature data, Taylor et al. () studied the characteristics of the mesospheric semi-annual oscillation (SAO) over Maui, Hawaii.
In the same line. Mesospheric Chemistry and Dynamics The mesosphere extends from the temperature maximum at the stratopause around 50 km altitude to the atmospheric temperature minimum at the mesopause around 85 km.
There has been much discussion of upper stratospheric and mesospheric chemistry in the context of the Ozone Deficit Problem (Crutzen at al. The Mesospheric Semi-Annual Oscillation in the mean zonal winds (MSAO) is a prominent feature of the tropical middle atmosphere.
This oscillation is thought to be driven by the selective. The Fe data are consistent with lidar data at Arecibo Observatory, N, which also has a summer maximum (Raizada and Tepley, ). At N lidar results at night show a winter maximum (Kane.
An analysis was performed of data on nine summer seasons () collected by the SME satellite to study large-scale geographical and temporal variability of polar mesospheric clouds (PMC).

The very first set of satellite data obtained from the altitude variations of the ultraviolet limb radiance measured by the Solar Mesosphere Explorer (SME) satellite covering the upper mesospheric region is analyzed by Clancy and Rusch () and later by Clancy et al.
They presented a five-year (–) morphology of mesosphere.  Long term variations of low‐latitude mesospheric semi‐annual oscillation (MSAO) and quasi‐biennial oscillation (MQBO) in the zonal wind are studied using observations available from to The MQBO showed large inter‐annual variability in the phase difference between km and km indicating such variability in eddy viscosity.
Abstract. We present an empirical model for nitric oxide (NO) in the mesosphere (≈60 –90 km) derived from SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartoghraphY) limb scan data.

Time series and trend analysis. It has been shown by Weatherhead et al. () that incorrect trends may result when only an average and trend is fit to data, such as those shown in Fig.
1 which display a high degree of correlation, a variability that is non-constant, and have a varying sample density.
Thus, in this section we discuss two approaches taken to assess the trends and. Modern astronomical instrumentation employs adaptive optics (AO) systems that correct for atmospheric distortion in real time in order to produce sharper images.
The design and performance of these systems relies on the knowledge of the atmosphere both at low and high altitude. This thesis investigates the first kilometer of the atmosphere, the ground layer (GL), as well as the sodium layer at.
A global three-dimensional model of the dynamics and chemistry of the mesosphere—lower thermosphere region (30–km) has been developed. This model i. Daytime zonally (longitudinally) averaged temperatures from the Wind Imaging Interferometer (WINDII) on the Upper Atmosphere Research Satellite (UARS).
Long term variations of low‐latitude mesospheric semi‐annual oscillation (MSAO) and quasi‐biennial oscillation (MQBO) in the zonal wind are studied using observations available from to T.
T he first published reports of noctilucent (“night-luminous”) clouds [[HN1]] appeared in (). These unusual clouds were widely observed to the north near midnight from Great Britain, Europe, and Russia.
It was immediately clear that they occurred at a very high altitude, because the entire lower atmosphere [[HN2]] was in darkness. Two-station photography established the. In addition, our results show that the diurnal variations themselves follow a semi‐annual variation, which is consistent with the reported semi‐annual variation of the bulges in the SME data.
 Our analysis of correlations with temperature is interesting from the scientific view and also helps validate the results. In the stratosphere.Observations from the Sounding of the Atmosphere with Broadband Emission Radiometry (SABER) instrument on the NASA/Thermospheric Ionosphere Mesosphere Energetics and Dynamics.
The transition between the middle atmosphere and the thermosphere is known as the MLT region (for mesosphere and lower thermosphere). This area has some characteristics that set it apart from other regions of the atmosphere. Most notably, it is the altitude region with the lowest overall temperature and has the unique characteristic that the temperature is much lower in summer than in .
