Chemiluminescence Instrument for NO, NO2, and O3 Data



This data set contains NSF/NCAR C-130 Chemiluminescence Instrument for NO, NO2, and O3 Data collected during the WE-CAN (Western Wildfire Experiment for Cloud Chemistry, Aerosol, Absorption and Nitrogen) field project from 24 July through 13 September 2018. This data set is in ICARTT format.

Additional information

Data Quality final
  • 0.1 (2018-11-07):

    RB Data: Initial archival, quick-look.

  • 0.2 (2018-11-09):

    R0 Preliminary Data:  O3 time adjusted to correlate with STRONG_VXL2, preferably, but also XSIG_UVH when STRONG_VXL2 not available or not useful. Still approximate calibration factors (zeroes, sensitivities, artifact); some hardwired to constants. NO, NO2 timing still TBD, but will be close.  

  • 1.0 (2019-03-20):

    R1: Final data. Aerodyne H2O (v. R1) used for sensitivity corrections, except for 20180813, for which Picarro H2O (v. R1) was used. Inlet leak of unknown magnitude through 20180809. Affects all 3 channels: NO, NO2, O3.
