Additional information

Data Quality final
  • 1.0 (2013-08-22)
  • 2.0 (2018-06-19):

    New, improved calibration results in ~14% decrease in OH and HO2. Some bad points removed.

  • 3.0 (2021-03-03):

    The Version 3 of this HOx data has higher temporal resolution, up to 5 Hz.  This data can show more spatial variability in the sampled airmass than the previously submitted 1 Hz data.  The integration is constant, with the shortest at 0.2 sec.
