-Agora que finalizamos todos os pre-processadorespodemos enfim trabalhar no processador principal, responsavel por gerar as saidas de concentracao de poluentes da regiao que iremos atuar.+Now that we've completed all preprocessorswe can finally work on the main processor responsible for generating pollutant concentration outputs for our study area.
  
 ===== 5.1. Introduction ===== ===== 5.1. Introduction =====
  
-AERMOD (American Meteorological Society/Environmental Protection Agency Regulatory Model) é um modelo de dispersão atmosférica desenvolvido pela EPA dos Estados Unidos em parceria com a AMS, com o objetivo de avaliar a qualidade do ar e estimar concentrações de poluentes atmosféricos provenientes de fontes industriaisEle é amplamente utilizado para estudos de licenciamento ambiental e avaliação de impacto de emissões atmosféricas.+**AERMOD** (American Meteorological Society/Environmental Protection Agency Regulatory Model) is an atmospheric dispersion model developed by the U.S. EPA in partnership with AMS, designed to assess air quality and estimate atmospheric pollutant concentrations from industrial sourcesIt's widely used for environmental licensing studies and air emission impact assessments.
  
-O modelo simula o transportedispersão e deposição de poluentesconsiderando a influência do relevometeorologia local e características das fontes emissorasAERMOD é especialmente recomendado para modelagem em escalas locais e regionais (até 50 km de distância da fonte).+The model simulates pollutant transportdispersionand deposition, considering terrain influences, local meteorology, and emission source characteristics. AERMOD is particularly recommended for local and regional scale modeling (up to 50 km from the source).

-O arquivo de fontes de emissoes infelizmente nao e de dominio publicoportanto estarei disponibilizando o {{ :emissions.rar | download}} aquiNao esqueca de extrair esse arquivo na pasta do ''C:\Users\Cliente\Desktop\AermodTutorial\5.AERMOD''.+The emission sources file is unfortunately not publicly availableso I'm providing the {{ :emissions.rar | download}} hereDon't forget to extract this file to ''C:\Users\Cliente\Desktop\AermodTutorial\5.AERMOD''.
  
 +===== 5.3. Configuring AERMOD =====
  
-===== 5.3. Configurando o AERMOD =====+First, we'll create two new folders within **AERMOD**:
  
-Primeiramente iremos criar duas novas pastas dentro do **AERMOD**, sao elas:+[[AERMET]] - Containing ''METAR.pfl'' and ''METAR.sfc'' data
  
-  * AERMET - Contendo os dados ''METAR.pfl'' e ''METAR.sfc'' +[[AERMAP]] - ''Bloomington.rec'' and ''Bloomington.src''
-  * AERMAP - ''Bloomington.rec'' ''Bloomington.src''+
  
-Agora que os arquivos estao armazenados corretamentedaremos inicio a criacao do **AERMOD**. +Now that files are properly storedwe'll begin creating **AERMOD**. 
-Para issocrie um documento de texto chamado ''AERMOD'', configure ele da seguinte maneira:+For thiscreate a text document called ''AERMOD'', and configure it as follows:

It is important that you use it only for comparison purposes or in case you are unable to make progress on the project. Here you can download the folder I used to create this document.
