13. The aim of this study is to estimate photodissociation life times of atmospheric trace gases at several altitudes because these gases make some effect on an increase in the global temperature. Photoabsorption cross sections of the gases have been measured and intensities of solar ultraviolet radiations were calculated.

13. Heterogeneous conversion of halogen reservoir molecules to active species on the surface of PSCs (polar stratospheric clouds) aerosol is thought of the most impotant role for antarctic and arctic ozone hole. In this research, we produce modeled PSCs in equibalent tempereture and pressure of polar stratospheric winter and characterize them. Thereafter, modeled PSCs will be compared with remote sensing data of ILAS instrument which will be installed in ADEOS satelite following by diagnose satelite arosol data. We also will be measure heterogeneous reactions on modeled PSCs.
