University of Hawaii, Barry Huebert, model TSI 3321 APS number distributions corrected for LTI enhancement. 
Aerodynamic diameter (micrometers), no stokes correction, assumed particle density of 1 g/cm3. 
Times correspond to MOI samples, approximately 30 min per sample. Data on 15-second time scales are available upon request.
APS distributions should not be trusted below 0.8 micrometer.
PASE research flights 2-14. August 10 through September 6, 2007.
