Strategic Direction: Chemical Weather

1. In order to enable the next generation of air quality management and prediction systems, develop the scientific knowledge needed to extend the time period of successful regional air quality forecasts to 7 days.

2. In order to facilitate seasonal air quality management and risk assessment, establish new multi-month predictive skills for the frequency of severe regional air pollution episodes.

3. In order to develop effective air pollution mitigation strategies, attribute the sources of pollutants responsible for adverse effects on human health and ecosystems.

Projects

  • MOPITT: Measurements of carbon dioxide are assimilated into CAM-Chem model runs on a daily basis.
  • TOGA: The TOGA instrument measures trace organic gases from research aircraft during field campaigns.
