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 61350 60600 62100 88888 68.5 88888 0.0 17.2 88888 88888 114.4 25.4 62745 62190 63300 4.7 88888 88888 0.0 88888 2.6 88888 88888 88888 64350 63870 64830 88888 1.8 88888 0.0 88888 88888 88888 0.8 88888 65385 64950 65820 1.1 42.1 88888 0.0 60.4 88888 88888 88888 88888 66870 65940 67800 63.8 77.0 88888 0.0 89.6 49.1 87.7 88888 4.2 69420 69120 69720 88888 88888 0.0 0.0 88888 0.0 0.0 7.9 88888 70470 69960 70980 41.4 44.2 88888 0.0 4.3 10.0 88888 88888 88888 71580 71100 72060 102.7 98.0 0.0 0.0 145.4 0.0 0.0 88888 88888 72630 72180 73080 88888 88888 88888 0.0 88888 88888 88888 88888 88888 73815 73230 74400 44.9 9.5 0.0 0.0 88888 0.0 0.0 46.9 5.5 75120 74550 75690 88888 1.4 88888 0.0 88888 88888 88888 1.0 88888 76275 75810 76740 80.9 5.0 7.5 0.0 88888 0.0 0.0 88888 88888 77265 76920 77610 117.1 92.3 88888 0.0 189.4 88888 88888 88888 88888 78225 77730 78720 119.7 7.1 88888 0.0 88888 0.0 0.0 88888 88888 79380 78840 79920 181.8 60.3 88888 0.0 159.0 0.0 0.0 88888 88888
