Product Tour

Surface Data (including 1-minute data)

The Surface tab in AERMET 7 allows surface data, typically from government weather stations, to be imported to AERMET. This includes 1-minute (AERMINUTE) wind data, which can easily be imported. When you specify a surface data file, AERMET will find the station in its internal database and fill in fields such as latitude and longitude automatically. Learn more


Upper Air Data

The Upper Air tab allows the user to quickly import data from an upper atmosphere sounding station, which is typically required in order to produce AERMOD-ready met data. Like the Surface tab, when you select your upper air data file in the Upper Air tab, AERMET will save you time by automatically filling out fields such as latitude and longitude. Learn more


Onsite Station Data

In addition to typical surface and upper air data, usually from government-operated weather stations, AERMET can import a wide range of meteorological data collected at on-site stations. These range from data from meteorological towers that measure wind and temperature at multiple heights to SODAR and wind profiler data. AERMET includes support for the Fortran FREE format, meaning data exported from spreadsheet software like Microsoft Excel can easily be imported.         Learn more


Land Use Data

The Land Use tab enables users to specify characteristics of the land use surrounding the meteorological station that are required for processing AERMOD-ready meteorological data. Learn more


Quality Assurance Tools

Producing a trustworthy meteorological dataset for AERMOD requires thorough Quality Assurance/Quality Control (QA/QC), including finding the root causes of error/warning messages, evaluating the accuracy of unusual data values, and ensuring that the final .SFC and .PFL files that will be used in AERMOD contain reasonable values. BREEZE AERMET provides a number of tools to make this easier. Learn more


Single-File Project Storage

AERMET processing can involve dozens of files: surface, on-site, 1-minute, upper air, and land use input files as well as a host of output and report files. AERMET 7 simplifies things by storing all of this data in one .ATZ zip file, making it easy to collaborate with co-workers or submit a file to a regulatory agency. Want to send someone just one particular file from your project? You can save individual files to a separate text file in AERMET 7, or you can unzip the entire .ATZ... Learn more
