The Air Resources Laboratory (ARL) uses cutting-edge atmospheric science and technology to improve the Nation’s ability to protect our health, our environment and our economy.
ARL studies the physical and chemical processes in the Earth’s boundary layer, which is the lowest part of our atmosphere and has a direct impact on us. This research primarily supports emergency management and homeland security.
How does the land interact with the air to affect temperature and humidity?
What processes dictate how something moves through the atmosphere? How can we improve the tools that predict how it moves and spreads?
How can we improve models and other forecast and prediction tools to better understand the atmospheric boundary layer?
