NSA/MPL/C1/C2 - No cross polarization data
DataStreams:nsamplpolC1.b1, nsamplpolavgC1.c1, nsamplpolavgC1.s1
Description:
Even though the polarization voltage was reported as switching between circular and cross 
polarization states, there was no cross polarization taking place because the 
polarization box had not been recycled following a system reboot.

You will not be able to create depolarization values.  However all other processes, such 
as cloud base determination should be ok.

HFE/MPL/M1 - Frosting/Condensation
DataStreams:hfemplpolM1.b1, hfemplpolavgM1.c1, hfemplpolavgM1.s1
Description:
On various days during the China deployment, condensation accumulated on the view port 
window of the MPL and compromised its capability to detect clouds.  This problem most often 
occurred during nighttime hours from May through early September.  

During the listed times, cloud retrievals and aerosol profiles should be considered 
doubtful or in error.
