A variety of volatile organic compounds (VOCs) play an important role in the global environment, such as depletion of stratospheric ozone, and aerosol formation. I have studied their sources, distributions and trends in attempt to understand their fate and impact in the environment. Major results include, (1) the discovery of strong emission of methyl chloride from tropical forests, accounting for most of its missing source, (2) the first detection of pinonaldehyde in the forest aerosol, providing an evidence of secondary biogenic aerosol, (3) the discovery of long-term variation of atmospheric methyl iodide which is likely linked to global environmental change, (4) development and the first application of high frequency measurements of VOCs including most volatile fluorocarbons in East Asia. I am highly honored to have been awarded the 2011 Geochemical Society of Japan Award.
