SGP/MWR/B5 - Intermittent missing data
DataStreams:sgpmwrlosB5.b1, sgpmwrtipB5.a1
Description:
Starting on 9/2/07 data have been intermittent due to frequent software crash. Large 
chunks (several days in duration) of data are missing. In March 2008 the fiber optics 
connections were checked and several faulty points were identified. The connections were 
repaired. Since then the instances of software crashes are much reduced.

SGP/MWR/B5 - Some rain events flagged
DataStreams:sgpmwrlosB5.b1, sgpmwrtipB5.a1
Description:
March 18 there was a strong rain event. During this time the brightness temperatures where 
> 100 K due to water accumulating on the radiometer, however the wet window flag 
indicator was not tripped.  Users should not rely on the wet window flag to screen 
rain-contaminated data.  Instead, apply a brightness temperature threshold of 100 K instead to both 
channels.
Measurements:sgpmwrtipB5.a1:
  • Total liquid water along zenith path using tip-derived brightness temperatures(liqtip)
  • 23.8 GHz sky brightness temperature derived from tip curve(tbskytip23)
  • 31.8 GHz sky brightness temperature derived from tip curve(tbskytip31)
  • Total water vapor along zenith path using tip-derived brightness temperatures(vaptip)
  • Water on Teflon window (1=WET, 0=DRY)(wet_window)
sgpmwrlosB5.b1:
  • Sky brightness temperature at 31.4 GHz(tbsky31)
  • Averaged total liquid water along LOS path(liq)
  • MWR column precipitable water vapor(vap)
  • Water on Teflon window (1=WET, 0=DRY)(wet_window)
