26 1001 Coffey, Hannigan, Mankin NCAR CO from TDL spectrometer ACCENT 1 1 1999 04 23 2000 08 11 0 Time (UT seconds) from 00 hours on flight date 1 1.0 999. CO mixing ratio, ppbv, 1, 0, 45.85, 202.88, -999, 0 0 11 CO mixing ratio is measured by long-path infrared absorption using the technique of tunable diode laser spectroscopy. Absorption at 2190.018 cm-1 is used in a 36 m path to detect CO. Observations are made once per second. Calibration is achieved by substituting the inlet flow with known mixtures of relatively higher and lower amounts of CO. Calibration and adjustment periods are excluded from the data set. For the data here a 'moving average' of 30 seconds of data is reported at the reporting interval of 10 seconds.
