SGP/WACR/C1 - Contamination with AMF WACR data
DataStreams:sgpwacrC1.00, sgpwacrC1.b1, sgpwacrspecmomC1.00
Description:
During this period we were doing an inter-comparison with the AMF WACR.  As a result, the 
AMF WACR contaminated the SGP WACR data.
Measurements:sgpwacrC1.00:
  • AVHRR satellite images for Darwin from BOM (RAW)(raw)
sgpwacrC1.b1:
  • PowerAmbientLoad
  • Temp_Antenna_Top
  • Cloud, reflectivity, at altitude(Reflectivity)

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

The sgpwacrC1.b1 data were reprocessed and archived in Sept 2010.  The 
sgpwacrspeccmaskcopolC1.a0 and sgpwacrspeccmaskxpolC1.a0 data were reprocessed and archived in January 2012.
Measurements:sgpwacrspeccmaskcopolC1.a0:
  • Cloud, reflectivity, at altitude(Reflectivity)
