AERSCREEN is a screening atmospheric dispersion model based on AERMOD, a likely alternative of SCREEN3 is a screening version of the ISC3 model.
The AERSCREEN will produce estimates of "worst-case" 1-hour concentrations for a single source, without the need for hourly meteorological data, and also includes conversion factors to estimate "worst-case" 3-hour, 8-hour, 24-hour, and annual concentrations.

Unfortunately, this model (<=AERMOD) is more complex and demanding then SCREEN3 (<=ISC3). Meanwhile, it would be intersting to find out if someone working in India, post the model evaluation results!

It is great to see that a new screening model with less complexity is now available. However, I wornder if it is usable for India?
