The concrete emergence of extended air pollution problems after World War II induced by long-range transport of airborne pollutants thousands of kilometres away from their source and the wide scale dispersion of radionuclides from bomb tests (reminded in 1986 by the Chernobyl accident) demonstrated the primary role of the atmosphere in influencing the state of our environment at all scales. Issues of environment and health as well as quality of life are thus directly connected to issues of air quality. Forecasts of extreme events are essential for managing the associated risks, whether social, regulatory or economic. The atmosphere is a formidable vector and processor of all natural and anthropogenic gaseous and particulate constituents as part of biogeochemical cycles. Meteorological processes and systems determine for a great part the fate of pollutants emitted into the atmosphere. Thus, all atmospheric scales from local (point and line sources, urban areas) to meso-, synoptic and global scales will disperse, mix, transport and deposit pollutants in a variety of ways and conditions. Environmental meteorology addresses the relationships and interactions between, on the one hand, meteorological processes and variability, and on the other hand, the chemical state of and processes in the atmosphere. These interactions have strong impacts on human health, ecosystems and the Earth environment at large including climate.
In an interdisciplinary perspective embedded in the concept of earth system science, it is thus relevant and beneficial to address the relationships between meteorological processes, atmospheric chemistry and pollution and the environment in a holistic way, where scale interactions have an important role. Furthermore, this implies that understanding, monitoring and predicting the state of the atmospheric environment requires improved approaches based on all available measuring techniques: ground-based, remote sensing, airborne and satellite-borne, while simulations and forecasts require advanced data-assimilation techniques to take full advantage of all the various measurements. Earth Observation (EO) technologies provide powerful tools for monitoring the state of the planet and the global impact of human activities. The session will aim at addressing the challenge that as both science and resolution advance, new stakeholders and a larger share of the public will expect more and better targeted meteorological-chemical forecasts and products.
We call for papers aiming at addressing these issues from both an observational and modelling or theoretical perspective as well as in an integrative way. The session on Environmental Meteorology is divided into 2 sub-sessions to better cope with the different scales of applications:
1) Meteorology and Atmospheric Pollution: from the urban to meso/regional scale
2) Global Environmental Monitoring and Forecasting (including GMES related issues)
Possible topics for sub-session 2 are:
· Atmospheric monitoring for global atmospheric issues (e.g., stratospheric ozone and surface UV-radiation, atmospheric composition and air quality);
· Forecasting and warning for extreme natural hazards;
· Intercontinental and inter-hemispheric transport;
· Long-range transport between local/regional scales to continental/global scales (i.e. both ways);
· Inverse modelling;
· Boundary layer-Tropospheric exchanges;
· Integrated system of systems (GEOSS, IGACO,…);
· Data-assimilation of satellite data and global data analysis;
· Integration of EO into operational monitoring and forecasting systems;
· Impact and monitoring of biomass fires;
· Treaty monitoring (CLTRAP, Kyoto, Montreal, ...);
· Meteorological constraints for developing integrated atmospheric services;
This sub-session will thus be a forum for presenting results of the GMES-projects GEMS and PROMOTE and SAF activities with strong connections with atmospheric dynamics, and to exchange ideas for future initiatives on global atmospheric monitoring and forecasting of the environment.
