SGP/WACR/C1 -  Reflectivity and Height Offsets
DataStreams:sgpwacrC1.b1, sgpwacrspeccmaskxpolC1.a0, sgpwacrspeccmaskcopolC1.a0
Description:
The instrument vendor has informed us of a range (height) offset of 13 m and has provided 
an updated reflectivity calibration.  All values reported for 'Reflectivity' are 
approximately 3 dB too low.   In addition, the Reflectivity in the first and fourth range gates 
(starting from the surface) need to be further corrected by an additional 2.7 and -0.9 dB, 
respectively. The 'height' field values are 13.33 m too low.  The data will be 
reprocessed to correct these problems.

Update:  The sgpwacrC1.b1 data were reprocessed to correct the height and reflectivity 
offsets.  The corrected data were archived 20100910-20100915.
