VAP : Raman LIDAR Vertical Profiles (RLPROF)
Instrument Categories
Aerosols, Atmospheric Profiling, Derived Quantities and Models
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. For more information about the Raman Lidar Profiles Best Estimate VAP (RLPROFBE), see the VAP report.
