ARTICLE-3: Research and systematic observations [go to this ARTICLE]
... The Parties undertake to promote or establish, as appropriate, directly or through competent international bodies and taking fully into account national legislation and relevant ongoing activities at both the national and international levels, joint or complementary programmes for systematic observation of the state of the ozone layer and other relevant parameters, as elaborated in annex I. ...
ARTICLE-Annex_I: Research and systematic observations [go to this ARTICLE]
... (d) Systematic observation on:
- (i) The status of the ozone layer (i.e. the spatial and temporal variability of the total column content and vertical distribution) by making the Global Ozone Observing System, based on the integration of satellite and ground-based systems, fully operational;
- (ii) The tropospheric and stratospheric concentrations of source gases for the HOx, HOx, Cl0x and carbon families;
- (iii) The temperature from the ground to the mesosphere, utilizing both ground-based and satellite systems;
- (iv) Wavelength-resolved solar flux reaching, and thermal radiation leaving, the Earth's atmosphere, utilizing satellite measurements;
- (v) Wavelength-resolved solar flux reaching the EarthÕs surface in the ultra-violet range having biological effects (UV-B);
- (vi) Aerosol properties and distribution from the ground to the mesosphere, utilizing ground-based, airborne and satellite systems;
- (vii) Climatically important variables by the maintenance of programmes of high-quality meteorological surface measurements;
- (viii) Trace species, temperatures, solar flux and aerosols utilizing improved methods for analyzing global data.
