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 60675 60270 61080 66.6 55.7 88888 88888 88888 88888 53.9 1.6 88888 62070 61380 62760 14.0 28.8 8.3 8.7 88888 88888 88888 15.3 3.4 63645 63120 64170 88888 3.8 26.5 88888 88888 3.3 88888 4.9 2.6 66720 65940 67500 88888 42.3 191.8 88888 4.8 88888 88888 3.3 88888 68250 67620 68880 88888 30.0 10.9 88888 12.6 88888 88888 18.3 5.6 69615 69000 70230 31.9 25.9 12.0 88888 88888 2.1 29.9 11.0 88888 71415 70290 72540 88888 88888 0.7 88888 88888 88888 88888 88888 88888 73545 73080 74010 88888 3.2 14.2 88888 88888 88888 88888 88888 88888 74865 74280 75450 88888 2.9 5.8 88888 4.8 88888 88888 8.2 57.4 76095 75690 76500 88888 30.2 26.3 88888 88888 88888 88888 33.8 17.6 77265 76650 77880 88888 88888 88888 88888 0.4 88888 88888 88888 88888 78525 78000 79050 4.8 88888 1.5 88888 88888 88888 88888 1.2 5.1 79815 79170 80460 88888 37.7 12.7 3.4 38.1 88888 88888 28.3 88888 81165 80580 81750 88888 42.6 36.0 88888 88888 88888 88888 8.8 6.5 82745 81870 83620 88888 88888 88888 88888 88888 88888 88888 88888 88888
