BREEZE AERMET Pro processes raw, hourly meteorological data files through three distinct modules or "stages":
- Stage 1: Extracts and quality checks weather station data. For international locations, mixing height parameters are calculated in this stage.
- Stage 2: Merges relevant data into a single file.
- Stage 3: Processes the merged file and calculates hourly values of planetary boundary layer (PBL) parameters for use in AERMOD. This stage requires the input of three site-specific, land-use parameters: surface roughness, Bowen ratio, and albedo.
BREEZE AERMET Pro includes modules for processing NWS data types (e.g. CD-144, TD-3505/ISH) AND for converting ADMS data files into AERMOD-ready format. Processing data from an onsite tower is easier than ever with AERMET Pro.
Stage 3 is included as a tool in BREEZE AERMOD so that merged data files purchased from vendors, such as BREEZE, can be processed with site-specific, land-use parameters.
BREEZE AERMET Pro contains many new and exciting features that make this the best version of AERMET on the market.
Tabbed Interface: Entering information to the program is simpler with the new display. All of the data required to run is a simple mouse-click of a tab away.- Warnings View: A handy pop-up window instructs the user where potential errors are in their current project file.
- New Reports: Our customizable reports view displays all of the project files, including the raw meteorological files!
- Sequential Navigation: Never wonder what information still needs to be entered. The sequential directions leads the user through the program so no details are left out.
- Easy-to-Read QA Tables: Our clear, concise quality assurance tables allow users to easily input their project-specific needs into AERMET.
- New Land-Use Features: Entering surface characteristics into AERMET can be as simple as copy and paste!
- BREEZE MetView: This tool allows you to view graphical and tabular windroses, view raw and model-ready meteorological data in an easy-to-read table, copy data to Microsoft® Excel®, and create custom graphs of available meteorological parameters.

Though developed in the United States, AERMOD has become one of the most widely-used air dispersion modeling programs throughout the world. This can lead to problems when trying to accurately generate AERMOD-ready meteorological data. AERMET was programmed to use raw, upper air sounding data that was recorded at sunrise and sunset. Since soundings are taken at 0000 and 1200 GMT, local time zone changes mean that the recorded data isn't technically correct for use in AERMET.
BREEZE AERMET Pro uses the PBLAER module to work around this problem. PBLAER uses a semi-empirical method to estimate the surface similarity parameters of friction velocity, sensible heat flux, temperature scale, and Monin-Obukhov length using routinely collected meteorological variables of cloud cover, ceiling height, wind speed, temperature, and estimates of surface roughness (all of which are already contained in raw, hourly surface meteorological data).
Are you looking for meteorological data to input into AERMOD? Not sure if AERMET Pro is right for you? You will need BREEZE AERMET Pro if you want to:
- Input raw meteorological data (surface and upper air)
- Convert ADMS data files to AERMOD-ready format
- Format on-site meteorological data for use in AERMOD
- Generate quality assurance reports detailing that your data meets current U.S. EPA guidelines
Perhaps you are the type of user that doesn't have their own raw meteorological data, but you want to be able to input your own land-use characteristics. You can purchase data from BREEZE and use the AERMET tool included in BREEZE AERMOD to enter your own site-specific, land-use characteristics.
So which is the right version for you?
