Aermod is a computer program that helps us understand how air pollution moves through the air. Imagine you are blowing bubbles with a bubble wand outside. If there is no wind, the bubbles just stay in one place. But if it's a windy day, the bubbles get carried away and move around a lot.
In the same way, pollutants in the air can move around a lot depending on the wind and other factors. Aermod helps us understand how pollution from things like factories or cars gets carried around by the wind and affects the air quality in different places.
Aermod takes a lot of information into account when making its calculations, like how tall a building is, how much pollution is being released, and how fast the wind is blowing. It uses all of this information to create a map that shows how the pollution is moving through the air and where it might end up.
This can help scientists and environmental experts figure out how to reduce pollution and make the air cleaner for all of us to breathe.
