| Summary: | The atmospheric composition is a societal issue and, following new
European directives, its forecast is now recommended to quantify the air
quality. It concerns both gaseous and particles species, identified as
potential problems for health. In Europe, numerical systems providing daily
air quality forecasts are numerous and, mostly, operated by universities.
Following recent European research projects (GEMS, PROMOTE), an organization
of the air quality forecast is currently under development. But for the
moment, many platforms exist, each of them with strengths and weaknesses.
This overview paper presents all existing systems in Europe and try to
identify the main remaining gaps in the air quality forecast knowledge. As
modeling systems are now able to reasonably forecast gaseous species, and in
a lesser extent aerosols, the future directions would concern the use of
these systems with ensemble approaches and satellite data assimilation. If
numerous improvements were recently done on emissions and chemistry
knowledge, improvements are still needed especially concerning meteorology,
which remains a weak point of forecast systems. Future directions will also
concern the use of these forecast tools to better understand and quantify the
air pollution impact on health. |
