TWP/MMCR/C3 - Diminished Reflectivity Sensitivity

Radar sensitivity was diminished by approximately 15 - 20 dBZ during
this period.  The result is that upper level cloud tops may be missed
and thin clouds, particularly thin cirrus, may not be detected during
this period.  Reflectivity was correctly calibrated, so values are
correct where signals were detected.  The problem was caused by
lightning damage to the low noise amplifier (LNA).  The LNA was replaced
on 20060718.

TWP/MMCR/C3 - Reprocess:   Height Error

A timing error was found in the PIRAQ MMCR's.  It resulted in recorded heights being too 
high for each radar mode by the following amounts: 
   Mode 1: 24.8756 m too high
   Mode 2: 25.6249 m too high
   Mode 3: 33.1176 m too high
   Mode 4: 33.1176 m too high
Range gate spacing was not affected.
