Data Set Description:

This file contains the Georgia Tech NO data set
from the ACE-1 experiment. Observations began at the
tabulated time and were 60 seconds in duration except for
the period after 22:44 UTC at the end of flight 4 when the
integration period was 10 seconds.

NOTES:

1)  Some of the reported concentrations are negative.  In
the past, the GT group has not reported negative
concentrations, however, the ACE-1 data were collected with a
chemiluminescence instrument and the data collectors have elected to
conform to reporting practices previously established for
this technology.

2)  The data have been corrected for background offsets by
using results of observations made while flushing the
sample inlet with zero air.  The reported uncertainties
represent one standard deviation and include systematic
effects (primarily flow sensor calibration accuracy) as
well as observed reproducibility.

3)  The instrument was not fully operational for flights
1, 2 and 3 so no data are reported for these flights.
