Envitrans develops and delivers on site and online training courses on air dispersion, tailored to the organization specific requirements.
Training CoursesWe provide Air Dispersion Model-ready Meteorological and Terrain datasets for any specific location. The data is pre-processed appropriately to the standards of U.S. EPA.
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 CALPUFF air dispersion models.
AERMOD-ready WRF data is generated using the US EPA Mesoscale Model Interface Program (MMIF) and produces data files for direct input to the AERMOD air dispersion model. The MMIF converts WRF model output fields to the parameters and formats required for direct input into dispersion models.
You will be provided with the following AERMOD model ready data files:
We provide AERMET compatible files in the following format:
From WRF data, MMIF can produce four output files (TXT, DAT, GRD, and AUX). These files consists of three-dimensional data spanning many vertical layers and covering a horizontal grid and domain specified by the client.
We process and provide both AERMOD and AERMET-ready meteorological data. Now, the question is which one do you need for your project! Note that land use parameters can change from place to place and season to season, so purchasing AERMET-ready meteorological data will enable you to input the desired land use parameters during the meteorological data processing through AERMET.
To run AERMET version 21112, the user can combine Stage 1, 2, and 3 control files into one control file. However, to ensure that the AERMET run is executed successfully, the user should follow these specific steps:
Terrain data are often a necessary part of air dispersion modelling. AERMAP, which is a terrain pre-processor for AERMOD; processes Digital Elevation Data and creates a file suitable for use within an AERMOD control file. This file contains elevation and hill-height scaling factors for each receptor in the air dispersion study.
We can provide Terrain Data in Digital Elevation Model (DEM) and National Elevation Dataset (NED) GeoTIFF formats. You can buy DEM tiles for most of the world. Each tile covers a block of land that is 1 degree of latitude by 1 degree of longitude (approximately 100×100 km), with a resolution of approximately 90 meters. We may also provide custom sized DEM tiles on demand.
