Is there any proper tutorial available on how to use CALROADS, CALPUFF and AERMOD model software?
I am not familiar with this particular dispersion model, but did you try a search on YouTube?

I may have to elaborate on that: If you want to apply an air dispersion model on technically sound ground, then you should either get an experienced person in your team or at least you should do the calculation using different independent methods. I found it relatively easy to tweak some model parameters to get the desired result (not AERMOD, but different models). When we used MISKAM for the first time, we employed the developer of the model for some time to steer us in the right direction.
I think the US Environmental Protection Agency's Support Center for Regulatory Atmospheric Modeling (SCRAM) may be the best overall resource related to dispersion modeling; it includes extensive resources on AERMOD and the other models. Now the user guides may not be the best tutorials on learning to use the models. There are both commercial and non-commercial training programs available on-line, such as that suggested by I. Riess.
I did search on AERMOD and CALINE 4 tutorials but couldn't find any relevant videos in youtube. But I will look into the link you have sent me. Thank you for your response.
Both of them are quite right. Aermod has both commercial and non commercial versions. The only difference ia the ease of use. I started using Aermod long back with the non commercial available from USEPA. There are several guides available with USEPA to learn the model. But be aware that a model performance is just as good as the input data. Be very cautious in selecting the input data otherwise it will be like Garbage In Garbage Out kind of situation. Lastly assessment if model output is the key to atmospheric dispersion modeling in the light of input data, baseline data, assumptions and limitations.
All the best
Rajat Singhal , So it is impossible to get the non-commercial version of AERODOD online?
Robert Vancelas Obiang Zogo No no infact you can directly download the AERMOD non-commercial without UI from USEPA website.
