NOAA Air Resources Laboratory

Description

The ARL site is a scientific research and modeling portal. Its mission is to improve the Nation’s ability to protect human and ecosystem health by studying the physical and chemical processes occurring from the soil up to about 2–3 miles in the atmosphere. It is the birthplace of the HYSPLIT model, the global standard for tracking the movement of air parcels.
