Our Process

The Atmospheric Dispersion Modeling Process

At Sullivan Environmental, we perform air dispersion modeling using primarily the following modeling platforms: AERMOD, CALPUFF, ISCST3, CAL3QHC, TOXST, SLAB, and SCREEN3. We use several different pre and post-processing meteorological and source processing programs including PCRAMMET, BPIP, CALMET, CALPOST, AERMET, MOVES, and others to support the modeling depending on the types of sources, meteorological data sets, and the specific project application(s).

Results-oriented

We partner with industrial, government, and commercial clients to deliver innovative, intelligent and cost-effective solutions.

Modeling

We provide onsite air monitoring services, assessment, sampling, and semi quantitative compound detection services.

Preparing to study

We then prepare to conduct a wide range of air quality studies and meteorological-related research.
