Subject:
NSA/GVR/C1 - Incorrect auxiliary measurements
DataStreams:nsagvrC1.a0, nsagvrC1.b1
Description:
Between 6/16 and 6/19 there was a software problem and the auxiliary measurements all were 
reading constant values. The brightness temperature measurements do not appear to be 
affected.
One of the incorrect measurements that may affect the use of the data is the surface 
temperature. This measurement should be disregarded. 

Measurements from a different instrument (such as the MWR) can be used to replace the GVR 
readings.
Suggestions: 
Measurements:nsagvrC1.a0:
  • Physical temperature of noise diode(temp_noise_diode)
  • 183.3 +/- 14 GHz warm load signal(warm14)
  • 183.3 +/- 14 GHz hot load signal(hot14)
  • Physical temperature of antenna feed horn(temp_antenna_feed_horn)
  • Component plate temperature(temp_component_plate)
  • 183.3 +/- 3 GHz hot load signal(hot3)
  • 183.3 +/- 3 GHz warm load signal(warm3)
  • Physical temperature of thermoelectric cooling plate(temp_thermoelectric_cooling_plate)
  • 183.3 +/- 1 GHz warm load signal(warm1)
  • 183.3 +/- 1 GHz hot load signal(hot1)
  • Temperature of the hot absorber at the tip(temp_hot1)
  • Temperature of the warm absorber(temp_warm)
  • 183.3 +/- 7 GHz warm load signal(warm7)
  • 183.3 +/- 7 GHz hot load signal(hot7)
  • Temperature of the hot absorber at the center(temp_hot2)
  • Temperature of external sensor(temp_ext)
