Sub-group for Variability Processes and Warming
Effect of Tropsopheric Ozone
This subject aims at obtaining observational data for tropospheric
ozone and its precursors in China, Russia and Japan for the purpose
of validation of chemistry-climate model that will be incorporated
into an integrated model for global warming, and to evaluate global
warming effect of tropospheric ozone.
For this purpose, year-around observation of ozone and carbon monoxide
are conducted at three mountain stations in China, Taishan (Shangton
Prefecture), Huashan (Shaanxi Prefecture) and Huangshan (Anhui Prefecture),
and at Russian baseline station at Mondy (East Siberia).
In order to verify and refine the tropsopheric photochemistry sub-model
slotted into the chemistry-climate model, intensive observational
campaign of atmospheric species including OH/HO2
radicals, the key species of the photochemical theory, will also
be conducted at several sites in Japan.
Further, for the purpose of evaluating global warming effect of
tropospheric ozone, emission inventories of ozone precursors and
greenhouse gases in Asia at present and in future till 2020 will
be estimated. Database with a 0.5 degree latitude-longitude mesh
will be provided for input to the chemistry-climate model.
