The Air Resources Laboratory (ARL) conducts research and development in the fields of air quality, atmospheric dispersion, and climate. Key activities include the development, evaluation, and application of air quality models; improvement of approaches for predicting atmospheric dispersion of hazardous materials; and the generation of new insights into air-surface exchange and climate variability and trends.

The goal of our work is to improve the Nation's ability to protect human and ecosystem health while also maintaining a vibrant economy.
