Subject:
MAO/PSAP/S1 - Operator reset of transmittance glitch
DataStreams:maoaospsap3wS1.b1
Description:
Appears that the Operator changed filter @ 03:15 and did not reset transmission until 
04:15. Then there was another transmittance discontinuity at 05:20. All data should be 
considered incorrect.
Suggestions: 
Do not use data
Measurements:maoaospsap3wS1.b1:
  • AOS PSAP3W transmittance, green channel(TrG)
  • AOS PSAP3W mass flow, mV(mass_flow_voltage)
  • AOS PSAP3W transmittance, green channel(transmittance_G)
  • Aerosol light absorption coefficient, nominal red wavelength at dry or reference
    RH(Ba_R_PSAP3W)
  • Diffusion flow valve position(dilution_flow_valve_position)
  • AOS PSAP3W flags(psap_flags)
  • Aerosol light absorption coefficient, nominal green wavelength at dry or

  • AOS PSAP3W transmittance, blue channel(TrB)
  • Aerosol light absorption coefficient, nominal blue wavelength at dry or
    reference RH(Ba_B_PSAP3W)
  • Flow setpoint(dilution_flow_setpoint)
  • Dilution flow rate(dilution_flow)
