Ok kiddo, do you remember how sometimes big factories or even cars emit gases and smoke into the air? These gases can be very harmful to both humans and the environment.
Now imagine if something bad happens, like there is a big fire or a chemical spill, and a lot of those harmful gases and particles are released into the air. It can be very dangerous for people living or working nearby, and it can even spread to other places far away.
That's where the National Atmospheric Release Advisory Center (NARAC) comes in. They are like superheroes who use science and technology to predict and track the movement of those bad gases and particles in the air.
They have very advanced computers and sensors that can simulate the ways that air moves and how the gases and particles will spread. They can also use information from weather reports, satellite images, and other sources to make their predictions even more accurate.
When there is a big release of harmful gases or particles, NARAC will work closely with emergency response teams to help protect people, decide who needs to evacuate, and figure out what needs to be done to clean up the area.
So basically, NARAC is kind of like a really smart weatherman, but instead of predicting rain or sunshine, they predict where bad gases and particles will go and help keep people safe.
