Species mixing ratio below stated limit of detection is indicated by 88888. Start and stop times (in Universal Time) for individual samples are reported in seconds of the day (1 day = 86400 sec.). Average uncertainties in mixing ratios are as follows: HNO3 (< 30 pptv +/- 35%; 30 - 100 pptv +/- 25%; >100 pptv +/- 20%); HCOOH (<100 pptv +/- 30% ;>100 pptv +/- 20%; CH3COOH (<100 pptv +/- 35%, >100 pptv +/- 20%). Absolute accuracy of pptv values is unknown, but we believe it to be +/- 10 - 20%. Direct questions about these data to R. Talbot or J. Dibb at: Institute for the Study of Earth, Oceans and Space, Morse Hall, University of New Hampshire, Durham, NH 03824.
