Dynamics of the Antarctic and Arctic mesosphere and lower thermosphere – Part 1: Mean winds
the Antarctic and Arctic mesosphere lower thermosphere Mean winds
2010/11/29
Zonal and meridional winds have been measured in the upper mesosphere and lower thermosphere at polar latitudes using two ground-based meteor radars. One radar is located at Rothera (68° S, 68° W) in ...
Daytime ozone and temperature variations in the mesosphere: a comparison between SABER observations and HAMMONIA model
Daytime ozone temperature variations the mesosphere SABER observations HAMMONIA model
2010/9/21
This paper investigates the latest version 1.07 SABER (Sounding of the Atmosphere using Broadband Emission Radiometry) tropical ozone from the 1.27 μm as well as from the 9.6 μm retrieval and temperat...
Study on the impact of sudden stratosphere warming in the upper mesosphere-lower thermosphere regions using satellite and HF radar measurements
sudden stratosphere warming the upper mesosphere-lower thermosphere regions satellite and HF radar measurements
2010/8/12
The occurrence of a sudden stratospheric warming (SSW) excites disturbances in the mesosphere-lower thermospheric (MLT) wind and temperature. Here, we have examined the high frequency (HF) radar wind ...
The 16-day wave in the Arctic and Antarctic mesosphere and lower thermosphere
16-day wave Arctic and Antarctic mesosphere lower thermosphere
2010/2/21
The 16-day planetary wave in the polar mesosphere and lower thermosphere has been investigated using meteor radars at Esrange (68° N, 21° E) in the Arctic and Rothera (68° S, 68° W) in the Antarctic. ...
Retrieval of water vapor profile in the mesosphere from satellite ozone and hydroxyl measurements by the basic dynamic model of mesospheric photochemical system
water vapor profile satellite ozone hydroxyl measurements basic dynamic model mesospheric photochemical system
2009/11/19
We propose an indirect method for retrieving a number of significant minor gas constituents of the atmosphere. The technique is based on the use of so-called basic dynamic models of atmospheric photoc...
Daytime SABER/TIMED observations of water vapor in the mesosphere: retrieval approach and first results
Daytime SABER/TIMED observations water vapor mesosphere
2009/11/19
This paper describes a methodology for water vapor retrieval in the mesosphere-lower thermosphere (MLT) using 6.6 μm daytime broadband emissions measured by SABER, the limb scanning infrared radiomete...
Satellite observations and modeling of transport in the upper troposphere through the lower mesosphere during the 2006 major stratospheric sudden warming
Satellite observations upper troposphere lower mesosphere major stratospheric sudden warming
2009/7/23
An unusually strong and prolonged stratospheric sudden warming (SSW) in January 2006 was the first major SSW for which globally distributed long-lived trace gas data are available covering the upper t...
Long-term behavior of the concentration of the minor constituents in the mesosphere – a model study
Long-term behavior minor constituents mesosphere
2009/5/6
We investigate the influence the rising concentrations of methane, nitrous oxide and carbon dioxide which have occurred since the pre-industrial era, have had on the chemistry of the mesosphere. For t...
The ASSET intercomparison of stratosphere and lower mesosphere humidity analyses
ASSET intercomparison stratosphere lower mesosphere humidity analyses
2009/3/13
This paper presents results from the first detailed intercomparison of stratosphere-lower mesosphere water vapour analyses; it builds on earlier results from the EU funded framework V "Assimilation of...
Small scale density variations of electrons and charged particles in the vicinity of polar mesosphere summer echoes
variations of electrons charged particles polar mesosphere summer echoes
2009/3/11
We present small scale variations of electron number densities and particle charge number densities measured in situ in the presence of polar mesosphere summer echoes. It turns out that the small scal...
Polar mesosphere summer echoes（PMSE）：Review of observations and current understanding
