Software Subscription Terms & Conditions
Important Notice
AERMOD Cloud®, CALINEpro™, and FDMpro™ are professional interfaces to US EPA air dispersion models. These tools require prior expertise in environmental modelling and are not substitutes for formal training.
If you're using this software for the first time, we strongly recommend not to subscribe yet. Without foundational knowledge, you may face serious operational issues and incorrect modelling results.
Please refer to the official user manuals available on the EPA websites to understand the basics before proceeding.

WRF Model-Ready Data
Envitrans offers modelled meteorological data for any specific coordinates using the Weather Research and Forecasting (WRF) mesoscale model. All WRF modelled data outputs are processed for direct input to the AERMOD, AERMET, and CALMET air dispersion models.
AERMOD-ready WRF data is generated using the US EPA Mesoscale Model Interface Program (MMIF), which prepares data files for direct input to the AERMOD air dispersion model. Conversely, CALWRF processes output from the WRF-ARW model to create a 3D.DAT file suitable for input into CALMET.
AERMOD Ready
You will be provided with the following AERMOD model-ready data files:
- Surface Met Data File (
*.SFC) - Profile Met Data File (
*.PFL)
AERMET Ready
We provide AERMET-compatible files in the following formats:
- Surface Met Data File: ONSITE Format (
*.DAT) - Upper Air Met Data File: FSL Format (
*.FSL) - AERMET Input Files for Stages 1, 2, 3 (
*.IN)
CALMET Ready
CALWRF is a software tool that processes meteorological data from the WRF-ARW model into a 3D.DAT (*.dat3) file format. This format is specifically designed for use with CALMET, enabling accurate preprocessing of meteorological data for environmental modeling and simulations.
Data Disclaimer
The WRF-processed meteorological data provided by our service are generated using publicly available datasets and numerical weather prediction models. While we strive to ensure accuracy and reliability, the data are provided "as is" without any express or implied warranties regarding completeness, accuracy, or suitability for any specific purpose.
Model results may include uncertainties due to input data quality, model configuration, and natural atmospheric variability. We do not accept liability for any loss, damage, or decisions made based on the use of this data. Users are advised to verify results independently before applying them to operational or regulatory purposes.
By using this data, the recipient acknowledges and accepts these limitations.
Renewal/AMC
Note: Software subscription/AMC renewals are handled through a separate process and cannot be added to the shopping cart.
