Lidar Soundings of Noctilucent Clouds and Temperatures during Day and Night in the Summer Mid-latitude Middle Atmosphere

چکیده
At the Leibniz-Institute of Atmospheric Physics in Kühlungsborn (54N, 12E) we have developed a daytime capable Rayleigh-Mie-Raman (RMR) lidar for the mesosphere. Temperature soundings are feasible up to approximately 75 km during the day and up to 90 km during the night. Furthermore, measurements are performed at high solar elevation angles of up to ∼60. In 2010 we performed first daylight observations, covering the whole June-July summer season. In this paper we present first results on absolute temperatures and their variation by e.g. gravity waves and tides. Daylight RMR soundings allow simultaneous observations of ice particles together with the OSWIN-VHF radar. OSWIN observes so-called Mesospheric Summer Echoes which require a sufficient electron density beside the existence of ice particles.

Mesospheric temperature soundings with the new, daylight-capable IAP RMR lidar
Temperature measurements by lidar are an important tool for the understanding of the mean state of the atmosphere as well as the propagation of gravity waves and thermal tides. Though, mesospheric lidar soundings are often limited to nighttime conditions (e.g., solar zenith angle > 96) due to the low signal-to-noise ratio during the day. By this, examination of long-period gravity waves and tid...

Ground-based temperature measurements by lidar are an important tool for the understanding of long-term temperature changes as well as the propagation of gravity waves and tides. Though, mesospheric soundings are often limited to nighttime conditions due to the low signal-tonoise ratio during the day. We developed a daylight-capable RMR lidar for temperature soundings in the middle atmosphere. ...
متن کاملFirst Lidar Observations of Middle Atmosphere Temperatures, Fe Densities, and Polar Mesospheric Clouds Over the North and South Poles
An Fe Boltzmann temperature lidar was used to obtain the first measurements of middle atmosphere temperatures, Fe densities, and polar mesospheric louds (PMCs) over the North and South Poles during the 1999-2000 summer seasons. The measured temperature structure of the mesopause and lower thermosphere regions in mid-summer at both Poles is consistent with the MSIS90 model. The density profiles ...

In summer 2001 a potassium lidar was installed near Longyearbyen (78 N) on the north polar island of Spitsbergen which is part of the archipelago Svalbard. At the same place a series of meteorological rockets (“falling spheres”, FS) were launched which gave temperatures from the lower thermosphere to the stratosphere. The potassium lidar is capable of detecting noctilucent clouds (NLCs) and of ...
