HYSPLIT Model Forecast

Smoke forecasts are produced by NOAA using the HYSPLIT dispersion model. The dispersion model is preconfigured to run over the entire country once-a-day using the daily 0600 UTC NAM meteorological forecast. One-hour average output maps of primary PM2.5 air concentration between the ground and 5 km are produced using the actual fire locations from the previous day. The dispersion simulation consists of two parts: 1) a 24 h analysis simulation run for the previous day, and 2) a 48 h forecast simulation. The smoke particle positions at the end of each analysis period are used to intitialze the next day's analysis simulation.

Click on the composite image above to enlarge. Fires are in red. Fire size has been increased so fires are visible in this view. Smoke, when detected by the analyst, is in gray. For more details, see the NOAA NESDIS HMS webpage.
