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.

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.

CALPUFF View – Customizing Land Use Properties
A major step in any CALPUFF modeling study is to calculate geophysical properties of the modeling domain. The CALPUFF modeling system contains several preprocessors to perform these calculations.

CALPUFF View: Mapping Land Use Data in Shapefile Format
Land use data is vital to air quality modeling because the types of land cover encountered within the modeling domain play a big role in calculating atmospheric stability. Turbulence parameterization will be very different in a heavily populated urban area compared to a flat, grassy field or a large body of water. Digital land use data is available in a wide variety of formats, and the new CALPUFF View Version 9.0 now allows users to import land use data in shapefile format.

CALPUFF View: Modeling Sub-Hourly Time Steps
In past modeling tips, we have discussed how to estimate sub-hourly pollutant concentrations using AERMOD, a Gaussian plume dispersion model with an hourly minimum time step. Now we look at how a similar concept can be modeled using a different modeling system – CALPUFF.
