چکیده

To better understand and quantify aerosol radiative forcing and reduce the uncertainty of its climate effect, it is of vital importance to realize the aerosol components classification and quantification. For this purpose, we developed a powerful lidar system employed a multi-channels spectrometer, with capabilities of providing high spatial and temporal resolution measurements of Raman scattering and fluorescence from atmosphere aerosols. Preliminary result shows lidar system well performance. The on-going measurement will make us get more observation data to better understand aerosol characterizations.

Fluorescence from atmospheric aerosol detected by a lidar indicates biogenic particles in the lowermost stratosphere

With a lidar system that was installed in Lindenberg/Germany, we observed in June 2003 an extended aerosol layer at 13 km altitude in the lowermost stratosphere. This layer created an inelastic backscatter signal that we detected with a water vapour Raman channel, but that was not produced by Raman scattering. Also, we find evidence for inelastic scattering from a smoke plume from a forest fire...

Development of the Hampton University Lidar System and the Crest Lidar Network

As a remote sensing technique, lidar is a staple of atmospheric measurement techniques. Short-wavelength scattering allows measurements from molecular and particle or aerosol components of the atmosphere. These features are of particular importance to studies of weather, climate, and the underlying radiative transfer processes that drive them. Furthermore, these quantities or the scattering pro...
