TWP/MPL/C1 - Poor polarization separation
The MPL was showing signs of laser wear, and was no longer correlating well with either the local VCEIL or the local KAZR. Instrument was not reporting any cloud signatures at night, and showes a notable lack of scatter near the surface. The data began to show signs of deterioration around 7/01 and slowly progressed. Upper level cloud detection algorithms are likely ok but ice descrimination is likely inaccurate.
