Managing Sources

As described in Creating Scenarios, there are several ways to add a Source Group to a Scenario. Two options can be found through the Scenario Context Menu, accessed by right clicking a scenario in the Project Browser:

Add Source Group

Creates a new, empty source group.

Import Retrospective Data

Creates a new source group by importing sources from a CSV file. Sample CSV files are included in the examples directory of the application.

A third option to add a Source Group to a Scenario is through the Source Group Context Menu, accessed by right-clicking a Source Group within a Scenario:

Clone

Creates a duplicate source group in the same scenario.

To manage the sources within the source group, right-click the Source Group name and select Show Source Table. This will open a table where sources can be added or removed and source properties can be viewed and edited.

By right-clicking anywhere in the source table, the Source Context Menu becomes available:

Add Source

Opens a submenu to add new sources with the following types:

Area Source corresponding to AREA in AERMOD

Circular Source corresponding to AREACIRC in AERMOD

Polygon Source corresponding to AREAPOLY in AERMOD

The default coordinates are set to Xs = 0 m and Ys = 0 m for the southwest corner of the rectangular area or center of the circle, and Zs = 0 m for an optional elevation of the source (SO LOCATION keyword in AERMOD). The default source parameters are set to Aremis = 1 g/(s m²) for area source emission rate, Relhgt = 0 m for release height above ground, and area is defined as either square area 100 m by 100 m in size or circular area with radius of 100 m (SO SRCPARAM keyword in AERMOD). You can edit the starting coordinates by double clicking in the source table, or selecting Edit Geometry.

Resample

Opens a submenu with the following options for resampling:

Application Start

Application Rate

Incorporation Depth

Flux Profile

Import

Adds additional sources from a GIS shapefile or AERMOD input file.

Edit Geometry

View and edit geometry of each individual source.

Edit Color

Edit the color of one or more sources. Sources will be drawn using in the Receptor Editor using the selected color.

Plot Flux Profile

Plot the scaled flux profile corresponding to the selected reference flux profile for the source.

Remove

Remove a highlighted source from a list of sources.

If the source group is empty and sources are to be added manually, the Source Context Menu provides only Add Source and Import options.
