NIM/WACR/M1 - Reprocessed: Reflectivity and Height Offsets
DataStreams:nimwacrM1.b1, nimwacrspeccmaskcopolM1.a0, nimwacrspeccmaskxpolM1.a0
Description:
The instrument vendor informed us of a range (height) offset of 13 m and provided updated 
reflectivity calibration.  All values reported for 'Reflectivity' were approximately 1.5 
dB too low. In addition, the Reflectivity in the first and fourth range gates (starting 
from the surface) needed to be further corrected by an additional 2.7 and -0.9 dB, 
respectively. The 'height' field values were 13.33 m too low.  The data were reprocessed to 
correct these problems.

The nimwacrM1.b1 data were reprocessed and archived in October 2010.  The 
nimwacrspeccmaskcopolM1.a0 and nimwacrspeccmaskxpolM1.a0 data were reprocessed and archived in May 2012.
