Welcome to the CGRER Forecast Webpage for ABC-Asia

The Atmospheric Brown Clouds (ABC) field campaign is taking place from October, 2004. This campaign will investigate the relationship between air pollution and climate issues over South, Southeast and East Asia. Center for Global & Regional Environmental Research at the Universioty of Iowa, is providing daily chemical weather forecasts in support of this experiment.

Two coordinated forecasts are produced daily. The tracer forecasts utilize the CFORS system, which contains a variety of air mass and emission markers calculated on-line inside the RAMS meteorological modeling system. Meteorological and tracer fields are produced with high time resolution. These tracers are not designed to produce absolute quantities but rather reflect air mass characteristics (for example, CO tracers is only primary CO, and does not include a background or contributions from hydrocarbon and methane oxidation). Photochemical and Aerosol forcasts are produced using the University of Iowa's STEM-2k3 model.
