Abstract

Effective monitoring of the atmosphere for potentially hazardous aerosol plumes in urban areas requires a lidar that produces high signal-to-noise backscatter returns, fine spatial resolution, rapid updates, eye-safety at all ranges, and long-range operation. A scanning elastic backscatter lidar with high pulse energy that meets these requirements was recently developed at NCAR. The latest upgrades to the lidar system include the use of a new Raman cell for wavelength conversion and a two-channel receiver for backscatter depolarization ratio measurements. Highlights from recent field tests of the system are presented and plans to improve the prototype, as well as construct an unattended and continuously operating version, are discussed.
