Subject:
SGP/AOS/C1 - Ozone instrument error
DataStreams:sgpaosC1.a0, sgpaosauxC1.a0
Description:
A switch on the front panel of the ozone instrument was left in the wrong position.  This 
resulted in a bad value for ozone concentration being logged for these periods.
Suggestions: 
Do not use these ozone data.
Measurements:sgpaosauxC1.a0:
  • Ozone sample pressure(O3_Press)
  • Ozone sample frequency(O3_Samp)
  • Ozone sample temperature(O3_Temp)
  • Ozone line temperature set point(O3_SetPt)
  • Ozone mode(O3_Mode)
  • Ozone zero concentration(O3_Zro)
  • Ozone span concentration(O3_Spn)
  • Ozone offset value(O3_Offset)
  • Ozone line temp. from thermocouple attached to heater(O3_LinHeater)
  • unknown(O3_Cont)
  • Ozone span value(O3_Span)
  • Ozone line sample temperature (omega temp. sensor)(O3_LinTemp)
