The Air Resources Laboratory (ARL) conducts research and development in the fields of air quality, atmospheric dispersion, climate, and boundary layer science. 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.

Our Mission is to improve the ability of the Nation to protect human and ecosystem health and to support a vibrant economy through advanced atmospheric sciences and technologies.

Laboratory Highlight

ARL Collaborates with NOAA's Web Operations Center on HYSPLIT Roll Out

ARL collaborated with the NOAA Web Operations Center (WOC) to deploy the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) transport and dispersion model to the WOC as a major part of the operational plume prediction system.
