Data flowchart for the RLPROF family. (Larger image available.)

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.
