On the two-day oscillations and the day-to-day variability in global 3-D-modeling of the chemical system of the upper mesosphere/mesopause region
two-day oscillations day-to-day variability global 3-D-modeling chemical system
2009/11/11
The integration of the photochemical system of the upper mesosphere/mesopause region brought evidence that the system is able to respond in a nonlinear manner under certain conditions. Under the actio...
The two-day wave in the Antarctic and Arctic mesosphere and lower thermosphere
two-day wave Antarctic Arctic mesosphere lower thermosphere
2009/9/11
There have been comparatively few studies reported of the 2-day planetary wave in the middle atmosphere at polar latitudes. Here we report on a study made using high-latitude meteor radars at Rothera ...
Carbon monoxide distributions from the upper troposphere to the mesosphere inferred from 4.7 μm non-local thermal equilibrium emissions measured by MIPAS on Envisat
Carbon monoxide distributions mesosphere MIPAS Envisat
2009/5/7
We present global distributions of carbon monoxide (CO) from the upper troposphere to the mesosphere observed by the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) on Envisat. Verti...
Thermodynamics of homogeneous nucleation of ice particles in the polar summer mesosphere
Thermodynamics of homogeneous nucleation ice particles polar summer mesosphere
2009/3/13
We present the hypothesis of homogeneous nucleation of ice nano-particles in the polar summer mesosphere. The nucleation of condensed phase is traced back to the first step on the formation pathway, w...
Rocket measurements of positive ions during polar mesosphere winter echo conditions
Rocket measurements positive ions polar mesosphere winter echo conditions

On 18 January 2005, two small, instrumented rockets were launched from Andøya Rocket Range (69.3° N, 16° E) during conditions with Polar Mesosphere Winter Echoes (PMWE). Each of the rockets was...
Observations of lunar tides in the mesosphere and lower thermosphere at Arctic and middle latitudes

2009/1/15
Meteor radars have been used to measure the horizontal winds in the mesosphere and lower thermosphere over Castle Eaton (52° N) in the UK and over Esrange (68° N) in Arctic Sweden. We consider a 16-ye...
The thermal and dynamical state of the atmosphere during polar mesosphere winter echoes
thermal and dynamical state atmosphere polar mesosphere winter echoes
2008/12/30
In January 2005, a total of 18 rockets were launched from the Andøya Rocket Range in Northern Norway (69° N) into strong VHF radar echoes called "Polar Mesosphere Winter Echoes" (PMWE). The ech...
On the efficiency of rocket-borne particle detection in the mesosphere
rocket-borne particle mesosphere
2008/12/15
Meteoric smoke particles have been proposed as a key player in the formation and evolution of mesospheric phenomena. Despite their apparent importance still very little is known about these particles....
A long-term comparison of wind and tide measurements in the upper mesosphere recorded with an imaging Doppler interferometer and SuperDARN radar at Halley, Antarctica

2008/10/31
Data from a near co-located imaging Doppler interferometer (IDI) and SuperDARN radar recorded since 1996 have been analysed in a consistent manner to compare the derived mean winds and tides in the up...
