Dataset: Cloud Cond Nuclei
Deployment: 61TG_3052

See SOIREE Preliminary Voyage Report
See Methods & Sampling section below as well

Instrument: TSI 3010 Condensation Particle Counter.
The measurement is the total condensation nucleus concentration for particles > around 10 nm diameter.
Period: 5/2/1999 06:22 to 28/2/99 20:13
Location: On board RV Tangaroa during Southern Ocean Iron Enrichment Experiment.
Data frequency: 1 sample every 108s
Sample inlet: Line run from roof of crow's nest above bridge.

NOTES
The CN concentration in diesel exhaust is large.
A primary use for this measurement is as an indicator of sampling contaminated air.
The main exhaust outlets on Tangaroa are located high on the fantail.
A wind from the stern can carry the exhaust plume forward over the crow's nest sample inlet.
Baseline (unpolluted) CN values are typically <= 200 cm^-3 at the SOIREE site.
Grossly contaminated air has CN > 10,000 cm^-3.
