HFE/WACR/M1 - Reprocess: Reflectivity and Height Offsets
DataStreams:hfewacrM1.b1, hfewacrspeccmaskxpolM1.a0, hfewacrspeccmaskcopolM1.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.
