ARTICLE-Annex_I: Research and systematic observations     [go to this ARTICLE]
... (i) Comprehensive theoretical models: further development of models which consider the interaction between radiative, dynamic and chemical processes; studies of the simultaneous effects of various man-made and naturally occurring species upon atmospheric ozone; interpretation of satellite and non-satellite measurement data sets; evaluation of trends in atmospheric and geophysical parameters, and the development of methods for attributing changes in these parameters to specific causes; ...
... (ii) Laboratory studies of: rate coefficients, absorption cross-sections and mechanisms of tropospheric and stratospheric chemical and photochemical processes; spectroscopic data to support field measurements in all relevant spectral regions; ...
... (v) The influence of UV-B radiation on: the sensitivities and activities of biological species important to the biospheric balance; primary processes such as photosynthesis and biosynthesis; ...
... Ground-level sources of NOx play a major direct role only in tropospheric photochemical processes and an indirect role in stratosphere photochemistry, whereas injection of NOx close to the tropopause may lead directly to a change in upper tropospheric and stratospheric ozone. ...
