This file is a reformatted version of the original AASE data, such that it
conforms to the exchange file format standards adopted for AASE II (S.E.G.).

Note: This is the best form for exchange of our BrO data. We average
      for about one hour to achieve a detection limit of 2 pptv or
      better. In addition, in order to obtain a fairly steady
      background signal, we average along flight legs where the density
      does not vary too rapidly. Thus, what you will find in this
      table is the average BrO volume mixing ratio in Column 2, the
      1 Sigma uncertainty based on Poisson statistics in the same
      units in Column 3, the average potential temperature (in Column
      4) along the flight leg segments of duration Delta T (in Column
      5), and the GOES time at the midpoint of that segment. To obtain
      a BrO mixing ratio in PPTV you can just multiply the raw numbers
      that appear in columns 2 and 3 by 0.1.

      The segments reported here were chosen to highlight differences
      between BrO in sunlight and in darkness, where I used a solar
      zenith angle of about 92 degrees to define the terminator
      for photolysis (based on some expectations from models), and
      to illustrate differences between BrO in or out of the
      chemically perturbed region, the edge of which I defined by
      the edge of the perturbation in ClO.

      If you have trouble reading this with your current software,
      you might check line 8 of our header where I have listed the
      time interval as 3000 seconds. We do not use a fixed time
      interval due to the nature of our averaging routine. So this
      number is pretty meaningless. I hope this presents no fatal
      problems. If you would like to have our raw 32 second BrO data
      binned or filtered along different flight segments or in a
      different way, please call me at (617) 495-5922...Darin Toohey
