NIM/WACR/M1 - Reflectivity and Height Offsets
DataStreams:nimwacrM1.b1, nimwacrspeccmaskxpolM1.a0, nimwacrspeccmaskcopolM1.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 1.5 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.
Measurements:nimwacrspeccmaskxpolM1.a0:
  • Cloud, reflectivity, at altitude(Reflectivity)
