AEREarth: Visualize AERMOD Files in Google Earth

AEREarth Example: AERMOD Area Source Visualization
Air Sciences’ staff recently developed a tool called AEREarth for users who would like to visualize AERMOD air dispersion model input data in Google Earth before running the actual model. The AEREarth tool takes AERMOD input data files (extension .inp, or .api if using Lakes) and translates them into Google Earth KML files. These files allow the user to see a three-dimensional (3D) rendering of all air pollutant emissions sources characterized in the input file. The tool also can accept AERMOD BPIP files (.ppp, .pip, or .bpi) into 3D buildings. This visualization tool allows users to evaluate whether a facility is correctly configured in AERMOD, and provides a useful QA/QC check of the model data prior to conducting a potentially time-consuming model run.

AEREarth is a practical tool for those involved in air quality permitting and compliance. The tool can handle very large data sets and all source types (point, line, area, volume, and pit), and it considers release heights and stack heights. AEREarth also uses absolute elevations rather than relative elevations.

Software such as Lakes Environmental also generates 3D mapping software files that are viewable through Google Earth to visually display model runs. However, these require a software license. In addition, these software packages use relative elevations (or ignore elevation altogether), which makes it difficult to gauge correct elevations for source types. Absolute elevation is used inside the AERMOD model, so it is crucial to be able to quickly and visually tell if the input data includes the correct elevation. In the Lakes Environmental software, for example, there is no easy visual way to perform QA checks on elevations. AEREarth allows a quick and easy way to audit AERMOD input data files before spending time running potentially erroneous input data files.

In addition to correctly handling elevation, AEREarth has customized source shape and attribute data to allow you to access all of the source parameters, and correctly visualize complicated volume sources such as haul roads.
