Subject:
PGH/AOS/M1 - Bad nephelometer calibration
DataStreams:pghaospsap3wM1.a1
Description:
A bad calibration was entered for both nephelometers. Poor quality CO2 gas was suspected. 
A good calibration was taken in March 2012 and applied to the data for the entire 
campaign in the .b1 level data product. Errors are expected to be small.
Measurements:pghaospsap3wM1.a1:
  • TrR
  • Absorption coefficient green, corrected for flow and sample area, 3 wavelength
    PSAP, 1 um size cut(Ba_G_Dry_1um_PSAP3W_1)
  • TrB
  • Absorption coefficient, green wavelength, 3 wavelength PSAP, low RH, 10 um size
    cut(Ba_G_Dry_10um_PSAP3W_1)
  • TrG
  • Absorption coefficient red, corrected for flow and sample area, 3 wavelength
    PSAP, 10 um size cut(Ba_R_Dry_10um_PSAP3W_1)
  • Absorption Coefficient Blue, corrected for flow and sample area, 3 wavelength
