Receptors are specific locations where AERMOD will compute a concentration or deposition value. In an AERMOD analysis, at least one receptor must be defined in order for the model to run successfully. To assist modelers in including receptors into their AERMOD scenarios, BREEZE AERMOD offers users with a wealth of options and ways for creating model objects and for entering their parameters. For example, in BREEZE AERMOD receptor elevations can be processed with the embedded U.S. EPA AERMAP program or they can be manually entered. BREEZE AERMOD also provides multiple ways for users to enter sources and receptors, whether it be by adding a model object in the Map tab, copying and pasting from an Excel spreadsheet, or manually entering the data in a data entry window.
Additionally, BREEZE AERMOD offers users the ability to quickly and easily generate 3D receptor grids via the Cartesian Grid model object, which allows for the computation of concentrations at multiple heights above ground level. A 3D Cartesian grid network includes an array of points identified by the X (east - west) and Y (north - south) coordinates, as well as the heights above ground level (Z Levels) for each 2D grid. This type of analysis is useful to determine the flow and density of the plume at a specific time, providing a more in-depth analysis.
Follow the steps below to see one of the ways users can quickly and easily set up 3D Cartesian receptor grid in BREEZE AERMOD:
