Measuring really small particles
In this picture, Cameron McNaughton from the University of Hawaii is filling a syringe with butanol, a colorless and mildly toxic alcohol, that is used inside instruments measuring particle number concentration on the NSF/NCAR C-130 aircraft. The instrument is called an “Ultrafine Condensation Nuclei Counter” and uses a laser to measures particles that are as small as 3 nanometers in diameter.
Cameron is a recent PhD graduate in Oceanography but specializes in intercontinental transport of air pollution and its effects on regional and global climate. Since 2000, he has participated in 8 airborne field campaigns, logging more than 650 hours as a "flight scientist". Cameron also brought his surfboard with him and is one of the few scientists who has been brave enough to go into the fairly cold Ocean!
