abstract = {Four cloud condensation nuclei (CCN) instruments were used
to sample size-selected particles prepared at the Leipzig
Aerosol Cloud Interaction Simulator facility. Included were
two Wyoming static diffusion CCN instruments, the continuous
flow instrument built by Droplet Measurement Technologies,
and the continuous flow Leipzig instrument. The aerosols
were composed of ammonium sulfate, levoglucosan,
levoglucosan and soot, and ammonium hydrogen sulfate and
soot. Comparisons are made among critical supersaturation
values from the CCN instruments and derived from
measurements made with a humidified tandem differential
mobility system. The comparison is quite encouraging: with
few exceptions the reported critical supersaturations agree
within known experimental uncertainty limits. Also reported
are CCN- and hygroscopicity-based estimates of the soot
particles' solute fraction. Relative differences between
these are as large as $40\%,$ but an error analysis
demonstrates that agreement within experimental uncertainty
is achieved. We also analyze data from the Droplet
Measurement Technologies and the two Wyoming static
diffusion instruments for evidence of size distribution
broadening and investigate levoglucosan particle growth
kinetics in the Wyoming CCN instrument.},
