Air Dispersion Modelling predicts how pollutants are dispersed in the atmosphere from different pollution sources taking into account building influences, topography, meteorology, downwind distances, and other factors.
Air Dispersion modelling is a mathematical simulation of how air pollutants disperse in the ambient atmosphere. The simulation uses mathematical equations and algorithms to characterize the atmospheric processes that distribute an air pollutant emitted by a source over a wide area. These models are used to estimate or to predict ground level concentrations (GLC) at selected downwind receptor locations of air pollutants emitted from sources such as industrial plants, mines, vehicular traffic or accidental chemical releases.
I am using AERMOD Cloud since 2013, the application has evolved very well over the time.
I like this interface because it very simple to use and contains almost all modules and features
I require for perform air dispersion modeling for EIA studies in India.

Gaussian Plume Air Dispersion Model
AERMOD Cloud ®
A truly integrated AERMOD air dispersion modelling system - AERMOD, AERMET, AERMAP and BPIPRM within ONE Interface.
Overview
AERMOD Cloud® is an integrated graphical interface of U.S. EPA's AERMOD Modelling System. AERMOD is a
Gaussian Plume Air Dispersion Model. AERMOD Cloud consists of pre-processors modules like
AERMET,
AERMAP,
BPIPPRM and the model, which enable smooth flow of the data across the modules and model.
The application is developed specially in compliance with the Regulatory Requirements and considering
limitations of availability of the meteorological data.
AERMOD Cloud is predominantly used in Environmental Impact Assessment (EIA) Studies for the modelling of the
dispersion of air pollutants from various emission sources like Point, Area, Volume, Open Pit, Line, and
Polygon Area etc.
AERMOD Cloud allows you to export isopleth layer from the modelling project to a
KML
file, which can then be opened and project in 3D in Google Earth. This allows modeler to overlay isopleth
on the quality images provided by Google Earth.
AERMAP
For complex terrain situations, AERMOD captures the essential
physics of dispersion in complex terrain and therefore needs elevation data that convey the
features of the surrounding terrain. In response to this need, AERMAP searches for the terrain
height and location that has the greatest influence on dispersion for each individual receptor.
This height is the referred to as the hill height scale. Both the base elevation and hill height
scale data are produced by AERMAP as a file or files which can be directly inserted into an
AERMOD input control file.
A modeling domain is the geographic extent that includes all the receptors and sources
specified in a particular AERMAP run. The domain also defines the region of significant terrain
elevations within which the terrain data points are included in the calculation of hill height
scales.
Note that the terrain files
are required even if the user is providing the receptor heights because the terrain data are used
to obtain the hill height scale for each receptor. If the user specifies the receptor elevations,
they can be entered in either feet, meters, or decimeters. The output receptor elevations will
always be in meters.
Features
Experience the power of a truly integrated AERMOD air dispersion modelling system with AERMOD Cloud. Our innovative platform combines AERMOD, AERMET, AERMAP, and BPIPRM into a single, user-friendly interface, making it easier than ever to model the dispersion of air pollutants from various emission sources.
Designed primarily for Environmental Impact Assessment (EIA) studies, AERMOD Cloud provides advanced capabilities for modeling the dispersion of air pollutants from point, area, volume, open pit, line, and polygon area sources. With AERMOD Cloud, you can take your air quality assessments to the next level and make more informed decisions about the environmental impact of your projects.
Preview Release

Truly Integrated
A truly integrated AERMOD modelling system, consists of pre-processors, like AERMET, AERMAP and BPIPRM and model within ONE interface for smooth flow of data.
Multi Source Modelling
Interface can handle multiple emission sources simulations simultaneously; like. Point (Vertical, Horizontal, Capped), Area, Volume, Open Pit, Line, Line Area, Polygon Area, Circular Area.
Built-in Terrain Data
The terrain data of 90 m resolution is built-in to run AERMAP and assess the impact of topography on air dispersion.
AERMET - Met Processor
The interface is integrated with AERMET, the meteorological data processor of AERMOD.
Includes feature to convert excel file into SAMSON file.
Missing Data Treatment
In case of missing meteorological parameters like mixing height, solar insolation, ceiling heights, cloud cover etc., the interface contains several modules to estimate and fill the gaps. The modules are developed as per the guidelines of CPCB, IMD and U.S. EPA.
Output Visualization
Advanced post-processing with automatic gridding and contouring. Customize isopleth levels, colour, transparency, labels, fonts etc.
Fast and Simple
Quick project setup by specifying a reference point (Latitude, Longitude) and modelling domain radius. Application automatically downloads geo-referenced base maps and configure AERMAP for elevation data.
Multi Pollutant Modelling
Interface allow you to run multiple pollutants with single project file. No requirement of
creating individual files for each pollutants.
Building Downwash
Integrated BPIPPRM model automate building downwash calculations without separate run.
WeatherLog®
The interface is integrated with our meteorological data server WeatherLog®. Through this server, User can download meteorological data of any coordinate across India within a few minutes.
