The summary data provided on this site are preliminary in the sense that they were produced using the data acquisition software, not the standard UND analysis software. Here are some specifics:
1. Ozone concentration needs a final calibration conversion before the numbers are absolute. The relative form is accurate.
2. The FSSP sizes are preliminary.
3. The 2DC sizes are preliminary. As a rough guide, 33 microns should be added to the mean diameters.
4. The 1DC sizes are also preliminary, and a rough guide is to add 200 microns to the mean diameters.
Fully calibrated data is available from UND (Mike Poellot).
