SGP/SIRS/E8 - Ventilator Fan Failure
DataStreams:sgpsirsE8.00, sgpsirsE8.b1, sgpsirs20sE8.a0
Description:
At the start time specified the PSP (down_short_hemisp) ventilator fan failed. PM replaced 
the fan 7/8/2008 1750.  Ventilator failure does adversely affect radiometer measurements 
but the extent has not been quantified.  Mentor suggests using component sum method 
detailed in SIRS instrument handbook where down_short_hemisp = down_short_diffuse + 
short_direct_normal * cos (zenith angle) for each time record.
Suggestions: 
Use down_short_hemisp with descretion or apply component sum method.
Measurements:sgpsirsE8.b1:
  • down_short_hemisp_std
  • down_short_hemisp_min
  • down_short_hemisp
  • down_short_hemisp_max
