"Species mixing ratios are reported in parts per trillion by volume, except for Be-7 and Pb-210."
Mixing ratio below limit of detection indicated as 88888.
Start and stop times (in Universal Time) for individual samples are reported
in elapsed seconds from 0:00 z of the day of takeoff.
Average uncertainties in mixing ratios are as follows:
"NO3 20%, SO4 13%, C2O4 10%, NH4 15%, K 20%, Mg 10%, "
"Ca 10%, Be-7 15%, Pb-210 20%. "
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:
