TWP/MPL/C2 - Power Oscillation

There is an oscillation that shows up in the reflected power and the power monitor.  This 
oscillation shows up clearly whenever there is an absence of low (< ~5 km) clouds. Cloud 
return signals tend to be much larger than the level of this oscillation; however, it may 
introduce problems for studying aerosol distributions.  The end date of this DQR is 
artificial in that this is as far as the QC went.
