Subject:
NSA/KAZR/C1 - Shift in reflectivity and signal-to-noise ratio.
DataStreams:nsakazrgeC1.b1
Description:
During this period the background reflectivity and signal-to-noise ratio fields had a 
shift in average value.  The reason is unknown.  It appears that reflectivities in 
hydrometeor regions have an offset of approximately 4-5 dBZ between the 'kazrge' (burst mode) 
reflectivities and the 'kazrmd' (chirp mode) reflectivities.  It is unclear which set of 
reflectivities is correct.
Measurements:nsakazrgeC1.b1:
  • Reflectivity, cross-polarization(reflectivity_xpol)
  • Reflectivity,co-polarization(reflectivity_copol)
