| Research Abstract |
We have developed a black carbon(BC) instrument. Using the BC instrument, aircraft campaigns have been conducted over the western Pacific and the Arctic. We measured various microphysical properties of BC aerosol(e. g., mass concentration, size distribution, mixing state) and showed spatial and temporal distribution, large-scale transport, transformation, and removal processes of BC. We also developed global and regional models that can represent the detailed BC microphysical properties. Model calculations were validated by measurements. Using these models, impact of BC on the Earth's climate has been evaluated quantitatively.
