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.Interactive Forecast Viewers: STEM & CFORS Forecasts
If you want to study current or previous scenarios instead of flight planning,
previous forecasts may be more helpful.
