I need help with air modelling. I want to model air pollution at a point surrounded by several stacks. What will I do and how? Please help.....

Barry's Response - Shoeb:

go to to download a model called ISC3 or ISC3prime if you prefer.

Download its manual to figure out how to run it.

If there are buildings to consider, download the BPIP or BPIPprm programs from this same site and learn how to include its results in your modelling.

Set up your stacks and points of interest in the appropriate places

You need a meteorological data set to determine how the air will transport the plumes. It should be for the area where the stacks will be.

If you want to try a really simple model without the need for meteorological data, look on the EPA site cited above for SCREEN3. It's fun easy and will let you know about the basics.

If you need to see one for a good example, you can download one from the government of my region. See and select one. The standard in most jurisdictions since 2010 or so has become AERMOD and/or CALPUFF, considerably more sophisticated models.

Have fun with this.

If you need these results and the air modelling becomes too complicated for you to embark on, email for further advice.

I think you have got the exact answer for you doubts and the question that you have asked was very relevant according to the circumstances. I didn't know much regarding air modeling, but after visiting this blog I think I have got some important points.

please guide me how i will prepare a model for air pollution for a mines. i have taken 10 samples with in 10 kms, it is ahilly mining with a predominant wind direction north east .

Barry's Response - Go to the US government SCRAM site and download SCREEN3 for air pollution modeling:

Assume the mine opening is a smoke stack with zero height, its actual diameter and room temperature. See if you can guess at an emission rate for the stuff you are concerned about (such as dust, coded as PM). Play with it a while and see what you get.

It a shame that air modeling wasn't more used throughout the history as acid rain was result of lack of it. good answer barry!

I think you answered her question and provided her with some good links. It is a very interesting question and I was interested to read your answer.

Hope the project goes well!

Will it work?

The design did not look attractive and convincing at the first impression.However hope you get some information soon.

My initial impression wasn't a good one. The first thing I saw was what looked to be an MSPaint drawing. Then I noticed the strange pattern on the banner. Then the poor quality of the buttons on the left. The poorly-placed Google Ads distracted from the text, as well. It all immediately drained any interest I might have in the website. I am far from motivated to browse the rest of the site. If I were, however, to search the site, I would hope that the other pages, if not of a better quality, were concise and well-laid out to get across what they needed to before my interest further waned.
