Air
Quality and Atmospheric Conditions
The air quality and atmospheric conditions cluster
group will be asked to address both ambient air quality issues
and issues linked to trans-boundary and global conditions.
The group will be asked to:
- Determine a national indicator of air quality
as determined by its impact on human health (e.g. population
weighted length of exposure to "unhealthy" air),
- Determine indicators of, or related to, emissions
of global importance that may track both ecosystem health
(e.g. global climate change/instability, ozone layer depletion)
and human health (e.g. greenhouse gases as an indicator
of fossil fuel use and ambient air quality). The group will
consider how to incorporate the spatial dimension of air
quality and atmospheric conditions in these indicators,
and
- Examine the feasibility of an indicator
of airborne pollutant inputs in terms of the demand created
for ecosystem services (waste disposal and assimilation).
For each sub-domain of air quality related
to human health and of contribution to global atmospheric
ecosystem quality, the group will be asked to develop no more
than three indicators, and to designate one preferred indicator
to the Steering Committee.
