In a previous modeling tip, we provided an overview of working with layers within Lakes Environmental Software products. In the popular AERMOD View application, the Plots tab lists all available contour plot output files for display and analysis.
WebGIS provides access to global geophysical data for air dispersion modeling, risk assessment, and other technical applications. Lakes Software’s commercial products – such as AERMOD View, CALPUFF View, and more – integrate WebGIS to automatically download terrain and land use data directly into projects.
The CALPUFF air dispersion model relies on three-dimensional gridded meteorological fields to simulate the transport, dispersion, and deposition of pollutants.
One of the cornerstones to working with Lakes Environmental Software products is the drawing area. This is where all objects and layers are displayed for viewing and editing. One tool users have to properly control what is displayed in the drawing area is the Overlays tab on the Tree View.
AERMOD, one of the most widely-used air dispersion models in the world for analyzing ambient air pollutant concentrations, is typically applied for a wide variety of buoyant and neutrally-buoyant releases. One recurring question about the model is what pollutants it can (or cannot) model. Coded into the model is a list of pollutant types used to identify the pollutant being modeled for a particular run.
CALRoads View is an air dispersion modeling package used to predict air quality impacts near roadways from both moving and idling vehicles. Three dispersion models are integrated into the application: CALINE4, CAL3QHC, & CAL3QHCR. The original design of these models accounted only for releases of particulate matter (PM), carbon monoxide (CO), or nitrogen dioxide (NO2) with no further support for other inert gases.
