Black carbon measurements were continuously conducted during the cruise using a laser-induced-incadescence BC analyzer (SP2, Droplet Measurement Technologies) located in the Research Information Center, to which ambient air was drawn through ~3-m-long conductive silicon tube. Sampling air was dried by a Nafion-type aerosol dryer placed in front of SP2 to avoid the condesation of water inside the tubing and instrument and to sample "completely dried" particles.

Laser induced incadescence BC analyzer (SP2, Droplet Measurement Technologies)
Realtime measurement of single BC-containing particle using a laser induced incandescence technique. The numbers of detected BC-containing particle in a minute interval were converted into the number concentration of BC-containing particles using the observed sampling flow rate. The minutely concentrations were averaged into daily concentrations.
