AERMOD View: Working with Labels

When working with Lakes Environmental Software applications, the drawing area affords users a lot of flexibility in how they add and visualize their project components. One way for users to make sense of the objects is to include object labels. These are controlled via the Labels tab on the Tree View.

Graphical Options: Contour Cut Off in Lakes Software Applications

When conducting an air dispersion modeling analysis, the ability to present high-quality graphical depictions of the output is extremely important. Such images provide context to modeled results, and they provide a valuable tool to modelers in understanding and explaining the model’s calculations.

AERMOD View: Distance Limitations

When conducting an air dispersion modeling analysis with AERMOD, a common question arises as to what limits – if any – exist on where calculations can be performed by the model. Understanding the range of the model’s validity is important in interpreting results.

AERMOD View: Post-Processing Lead Concentrations in AERMOD with LEADPOST

In the United States, the National Ambient Air Quality Standard (NAAQS) for Lead is 0.15 µ/m3 as a rolling three-month average. This differs from other NAAQS in that it uses a rolling period, so a new three-month period is calculated with each successive month (e.g., January-March, February-April, etc.).

Lakes Software Applications: Using Annotations

One feature of Lakes Software applications that our users have come to appreciate, is the wealth of customization options available to provide high quality visualization of model output. Beyond the usual drawing tools for adding model objects, each application contains a set of Annotation Tools which allow users to add additional objects to the main display.

AERMOD View: Ontario: How to Handle Missing Elevations

As we described in a previous Modeling Tip, the Ontario Ministry of the Environment, Conservation and Parks (MECP) now distributes Canadian Digital Elevation Model (CDEM) data in GeoTIFF format via a portal on their website.
