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 63750 63420 64080 47.1 121.0 9.0 16.2 166.5 34.8 88888 292.6 52.7 64890 64140 65640 375.5 312.0 88888 81.6 767.3 88888 88888 595.1 123.9 66480 65940 67020 29.0 8.4 88888 5.0 88888 2.0 88888 13.0 2.9 67890 67380 68400 88888 8.1 17.9 3.5 88888 32.2 9.9 13.7 4.2 69150 68640 69660 217.5 75.5 0.1 15.9 101.4 88888 88888 18.6 4.9 70290 69780 70800 88888 11.8 5.3 3.5 11.6 16.6 88888 88888 88888 71220 70920 71520 129.1 10.3 88888 8.8 88888 88888 88888 19.2 88888 71970 71580 72360 269.6 52.6 88888 16.1 57.2 88888 88888 3.6 88888 72840 72480 73200 88888 38.8 88888 18.6 8.2 6.8 29.4 88888 88888 74132 73293 74970 7.1 1.0 88888 0.3 88888 88888 88888 88888 88888 75525 75060 75990 1.6 88888 88888 8.5 88888 88888 88888 88888 88888 76875 76110 77640 545.2 427.6 13.9 54.3 749.2 52.4 114.5 629.4 98.3 78675 77730 79620 88888 47.9 88888 8.6 76.8 88888 88888 88888 88888 80490 79740 81240 194.8 65.9 88888 12.2 116.7 74.9 178.1 9.8 88888 81994 81360 82628 81.2 37.2 88888 16.3 88888 27.5 64.9 7.9 3.5 83584 82920 84248 88888 9.1 88888 88888 24.5 88888 88888 88888 88888 85140 84780 85500 30.3 6.6 88888 88888 11.8 1.1 12.9 0.9 88888
