"RLPROF" VAP Process
Instrument Categories: Aerosols, Atmospheric Profiling, Derived Quantities and Models
Description: Raman LIDAR Vertical Profiles
The Raman lidar automatically attempts to reoptimize the position of the laser beam in the detector's field-of-view every few hours (this is required for most narrow field-of-view lidar systems). However, this can introduce alignment artifacts in the narrow field-of-view data due to the way the detection channels are arranged on the optical bench. A suite of vaps have been developed to reduce or remove any artifacts introduced in the narrow field-of-view data by these automatic self-alignment "tweaks." For more details, see each VAP process web page of the Raman Lidar Profiles: Aerosol Scattering Ratio, Best Estimate Product, Depolarization Ratio, Aerosol Extinction, Mixing Ratio and Merge.
For more details about the Raman Lidar preliminary quicklook images, see the calendar.
