| Outline of Final Research Achievements |
A method for determining the uptake coefficients of RO2 radicals onto aerosols by combining laser-pump radical generation and laser-induced fluorescence radical detection was established. The uptake coefficients of various RO2 radicals into inorganic and organic aerosols were examined in laboratory experiments. We also developed a method for direct determination of the uptake coefficients of RO2 onto atmospheric aerosols, and applied for determination of the uptake coefficients of isoprene-derived RO2 by atmospheric observation. Assuming that the obtained uptake coefficient of isoprene-derived RO2 onto atmospheric aerosol is representative, the ozone formation suppression effect up to 8.5% was estimated after sunrise under the observed conditions.
