Modeling Software for EHS Professionals

Acquiring data, verifying quality, and processing it into a model-ready state can be a costly, time-consuming process. Our long history of data processing enables us to handle your non-standard meteorological data processing needs with expertise and efficiency.

We offer data for the following modeling applications:


AERMOD, the preferred model of the U.S. EPA for near-field air dispersion modeling, requires the use of two meteorological files: the surface (.SFC) and profile (.PFL) files. BREEZE meteorologists can provide you with AERMOD-ready datasets that are checked and quality assured according to U.S. EPA standards. Our staff will help you identify the most appropriate station for your project and, if necessary, fill data according to regulatory standards.

We also generate land use characteristics specific to your chosen meteorological station. For locations within the United States, the latest version of AERSURFACE is used to generate land use characteristics.


CALPUFF utilizes meteorological data from prognostic meteorological models and/or observational data, which necessitates even more expertise and greater processing resources than models such as AERMOD. Preparing meteorological data for CALPUFF modeling is time-intensive due to the several processing steps and large data files involved. Our unique combination of computing infrastructure and professional meteorologists allow BREEZE to process your data in a timely manner.

BREEZE provides a viable, cutting-edge alternative to traditional, less sophisticated meteorological data sets that may produce overly conservative modeling results. This can be done for any number of surface and upper air sites over any domain size and resolution. The resolution of the WRF / MM5 mesoscale meteorological model (12 km, 4 km, or 1 km) accounts for the meteorological changes associated with variations in terrain.

Mesoscale Meteorological Data - WRF / MM5

WRF / MM5 data sets have high resolution, to represent meteorological changes associated with variations in terrain, and therefore provide precise meteorological parameters.

CALPUFF-ready data can be generated using WRF/MM5 model data. WRF data can be run through the CALWRF processor for use in CALMET, the meteorological preprocessor for CALPUFF. MM5 data can be run through the CALMMM5 processor for use in CALMET. When WRF/MM5 data is used, CALPUFF provides more accurate characterization of atmospheric dispersion, which often leads to less conservative modeling results than other models. AERMOD-ready data can also be generated using WRF/MM5 model data.

We consider the site-specific conditions and options for the project domains when preparing each WRF/MM5 data set. BREEZE possesses the infrastructure, expertise, and requisite raw data to create custom WRF / MM5 mesoscale data sets for locations around the globe. 

Custom Datasets

BREEZE meteorologists can customize meteorological data for a wide range of applications including raw data from on-site towers as well as other observation networks for input into air quality models. BREEZE trained meteorologists can also perform quality assurance analyses to ensure proper formatting and pre-process completeness on your data.

Our wealth of knowledge and extensive history in working with meteorological data make BREEZE the best choice for your custom meteorological needs.
