Air dispersion model

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 http://www.epa.gov/scram001/dispersion_alt.htm 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 http://environment.alberta.ca/623.html 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 info@calvinconsulting.ca for further advice.

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

http://www.epa.gov/scram001/dispersion_screening.htm

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!

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.
