AERMOD Wizard features a clickable map interface that allows you to quickly and efficiently find and download:

  • Surface and upper air meteorological data for US stations
  • Ambient monitoring data for criteria pollutants from the EPA AirData system

With the downloaded meteorological data, you can call and run AERMET and AERMINUTE to process raw data into an AERMOD-ready format.

With the ambient monitoring data, AERMOD Wizard can create an AERMOD-ready background data file that can be built using any of the temporal modes in AERMOD.

If you’re conducting Tier 3 NO2 modeling with the AERMOD’s OLM or PVMRM algorithms, AERMOD Wizard can construct an hourly ozone file for you.  AERMOD Wizard also includes routines for statistical evaluation of the raw data, such as maxima, minima, missing hours of data (by quarter), etc.

Other data analysis tools include the wind rose, pollutant rose, and forward/backward trajectory tools. Wind rose, pollutant rose, and forward/backward trajectories can all be exported to Google Earth. The trajectory tool can also plot the trajectories on AERMOD Wizard’s map interface or write a text file of all trajectory points.
