SGP/MMCR/C1 - Reprocess: Incorrect units for "heights" field
DataStreams:sgpmmcrmomC1.b1
Description:
The "heights" field metadata indicates that units are "m AGL" (meters above ground level) 
when in fact the heights data are recorded in "m MSL" (meters above mean sea leavel).
Measurements:sgpmmcrmomC1.b1:
  • Array of heights for each power(heights)

Subject:
SGP/MMCR/C1 - Polarization Mode Problem
DataStreams:sgpmmcrmomC1.b1, sgpmmcrspecmomC1.a0
Description:
The cross-polarization and co-polarization modes (6 and 5) were measuring 
cross-polarization only.  This means that one of the control signals was not hooked up correctly.  The 
signals were rerouted on 4/23/2008.

The General Mode (mode 3) is a co-polarization channel and worked during this time period. 
 The reason why we don't use the general mode all of the time is that the co-pol and 
cross-pol modes are temporally closer and make a better estimation of linear depolarization 
ratio.
Measurements:sgpmmcrmomC1.b1:
  • MMCR Mean Doppler Velocity(MeanDopplerVelocity)
  • Signal to Noise Ratio(SignalToNoiseRatio)
  • MMCR Reflectivity(Reflectivity)
  • MMCR Spectral Width(SpectralWidth)
sgpmmcrspecmomC1.a0:
  • MMCR Mean Doppler Velocity(MeanDopplerVelocity)
  • MMCR Spectral Width(SpectralWidth)
  • MMCR Reflectivity(Reflectivity)
