+Before starting to work, it is extremely important that we define the file creation folder.
+First, create a folder on the desktop called ''AermodTutorial'' (it will be addressed roughly like this: ''C:\Users\Client\Desktop\AermodTutorial''). Now, create 5 new subfolders inside it, where we will work with each of the processors, as we can see in the [[#Figure 1|Figure 1]]. They are:
+  * 2.[[aerplot|AERSURFACE]]

+===== What is AERMOD? =====
 **AERMOD** (American Meteorological Society/Environmental Protection Agency Regulatory Model) is an atmospheric dispersion model developed by the **U.S. EPA** (Environmental Protection Agency) in collaboration with the **American Meteorological Society (AMS)**. It is designed to assess air quality by estimating pollutant concentrations emitted from industrial and other stationary sources.

+This document is not only a tutorial for running [[aermod|AERMOD]], but also a comprehensive technical guide. The objective is to simulate a real-world dispersion scenario in ''Bloomington, Illinois (IL)'', using:
-  * Wind minute-resolution data from [[aerminute|AERMINUTE]], covering the entire year of ''2024'';
   * Land cover data from the year ''2023'', as they are the most recent available for surface parameterization using ''[[aersurface|AERSURFACE]]'';
-  * Pre-processing tools such as [[aermet|AERMET]], [[aersurface|AERSURFACE]], [[AERMAP]], and [[AERMOD]] itself;

   * Result visualization using the [[aerplot|AERPLOT]] utility.

 ===== How it works =====
-AERMOD simulates the transport and dispersion of pollutants in the atmosphere based on local meteorological conditions, terrain features, and emission source characteristics. The model requires preprocessed input data from auxiliary tools, including:

 ===== Notes =====
-[[aermod|AERMOD]] is recognized as a regulatory model by the U.S. EPA and is widely adopted internationally — including in ''Brazil'' — for environmental impact studies involving atmospheric emissions.

+  - The only operating system capable of running [[aermod|AERMOD]] is Windows.
+  - We will work with data from a full year (2024) for processing in [[aermet|AERMET]] in order to obtain more realistic output data from [[aermod|AERMOD]], but the user is free to choose any desired time period.
+  - For the simulation period in [[aermod|AERMOD]] itself, we will generate outputs for only one day, in order to ensure better optimization for our future work.
+  - With this document, we ensure its applicability to the entire ''United States'' and a large part of the globe.
