Inertia gravity wave in the stratosphere and mesosphere observed by Doppler wind and temperature lidar

Mobile Rayleigh Doppler lidar for wind and temperature measurements in the stratosphere and lower mesosphere.

A mobile Rayleigh Doppler lidar based on the molecular double-edge technique is developed for measuring wind velocity in the middle atmosphere up to 60 km. The lidar uses three lasers with a mean power of 17.5 W at 355 nm each and three 1 m diameter telescopes to receive the backscattered echo: one points to zenith for vertical wind component and temperature measurement; the two others pointing...

An Investigation of Gravity Wave Activity in the Low-latitude Mesosphere: Propagation Direction and Wind Filtering

The atmospheric background situation in northern Scandinavia during January/February 2003 in the context of the MaCWAVE campaign

The atmosphere background wind field controls the propagation of gravity waves from the troposphere through the stratosphere into the mesosphere. During January 2003 the MaCWAVE campaign took place at Esrange, with the purpose of observing vertically ascending waves induced by orography. Temperature data from the U. Bonn lidar at Esrange (68 N/21 E) and the ALOMAR RMR lidar (69 N/16 E), wind da...

Stratosphere temperature measurement using Raman lidar.

Temperature measurements using vibrational Raman scattering from molecular nitrogen were performed simultaneously with temperature obtained by Rayleigh scattering in the amplitude range between 12 and 30 km. The downward extension of the Rayleigh temperature described in this paper leads to the possibility of obtaining a continuous temperature profile from 12 to nearly 100 km. The temperature p...
