Mixing ratio below limit of detection indicated as 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: NO3 20%, SO4 13%, Cl 30%, C2O4 10%, NH4 15%, K 20%, Na 35%, Ca 15%, Mg 10%. Please note that it is not possible to use these data on time scales shorter than reported here. The most useful and appropriate method of comparing the UNH aerosol data to other SUCCESS data is to average the higher resolution measurements over the reported aerosol sampling time intervals. 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. e-mail: rwt@christa.unh.edu or jed@unh.edu 67830 67260 68400 88888 54.2 88888 88888 128.7 88888 88888 4.4 5.3 69000 68490 69510 88888 18.5 88888 88888 24.6 9.6 88888 88888 4.8 70065 69630 70500 81.6 6.4 88888 88888 38.2 88888 88888 3.0 9.3 71190 70620 71760 88888 1.4 88888 88888 5.4 88888 88888 88888 88888 72255 71880 72630 88888 52.2 88888 88888 84.6 88888 88888 3.6 7.4 73290 72780 73800 16.8 56.7 88888 88888 134.6 11.4 88888 11.3 11.5 74295 73920 74670 88888 58.9 88888 88888 116.6 88888 88888 88888 88888 75375 74790 75960 51.3 61.8 13.8 88888 194.3 88888 88888 10.6 10.0 76470 76050 76890 29.7 6.2 6.0 88888 17.8 88888 88888 88888 88888 77640 77010 78270 88888 53.9 18.3 88888 146.0 88888 88888 88888 88888 78780 78360 79200 9.8 88888 88888 88888 190.9 88888 88888 88888 88888 79950 79380 80520 102.3 13.2 88888 88888 60.7 88888 88888 65.0 4.4 81030 80580 81480 88888 13.6 88888 88888 15.3 88888 88888 1.4 2.7 82230 81600 82860 51.2 53.1 6.7 88888 77.9 88888 88888 17.1 10.7 84105 83340 84870 10.2 43.3 88888 88888 70.9 14.8 20.4 7.9 4.7
