Description

The naturally exist mesospheric Na layer, overlapping upper mesosphere and lower thermosphere, provides an excellent tracer for lidar remote sensing. The Na Doppler lidar technique is designed to measure neutral temperature and wind profiles in the mesopause region (~ 80-110 km) by observing the thermal broadening and Doppler shift of atomic Na fluorescence spectrum. Relocated from Colorado State University (CSU), the Na lidar at Utah State University (USU) has been operating since summer 2010 with operation hour of roughly 1000 hours per year. Enabled by a pair of Faraday filters, it has unique daytime observation capability to study not only small scale dynamics features, but also large scale tidal and planetary wave activities. Combined with the lidar database at CSU, this project has the longest mesopause region temperature database in the world (29 years and counting). This invaluable database has enabled several long-term trend study in the upper atmosphere, which is mostly related to the increasing CO2 diffusion from troposphere into the upper atmosphere and the stratosphere contraction.

Award Title

Collaborative Research: A Consortium of Resonance and Rayleigh Lidars; Fundamental Coupling Processes in the Mesosphere, Lower Thermosphere (MLT) Using Enhanced Na Wind-temperature Lidar Measurements at the Atmospheric Lidar Observatory

Methodology

The lidar hardware is set up so that the lidar signals were binned with 150 m in line of sight direction and saved every minute. Different temporal and spatial resolutions can be applied later during data processing, when the temperature and wind information in the upper atmosphere are derived.
