| Research Abstract |
Uptake coefficients of HO2 radical with levoglucosan and dicarboxylic acids particles were measured. The results have the relative humidity dependence of determined uptake coefficients, suggesting water complex contribution for heterogeneous loss of HO2.We also carried out global chemical modeling using uptake coefficients of HO2 we have determined. Results suggested the potential importance of the heterogeneous reactions of HO2 radicals with aerosol particles in the areas with high aerosol loading for not only HO2 concentration, but other relevant species.
