LOCATION: Aircraft location data in file TN_20070728.DC8. ASSOCIATED_DATA: N/A INSTRUMENT_INFO: Chemical Ionization Mass Spectrometer. Direct measurements in ambient air. DATA_INFO: Measurements are reported as 0.5 sec averages and in units of pptv. CAUTION: Do not extrapolate data outside of given time interval as these are discrete measurements. Calibration was conducted ~once per hour during the flight using H2O2 and HNO3 calibrants, and proxied to PNA using laboratory calibrations. Absolute calibration was obtained in the laboratory by thermal decomposition and NO2 measurement. Zeros were conducted ~3 times per hour by passing ambient air through a filter containing nylon wool coated with NaHCO3.
