Air Resources Laboratory
ARL studies the boundary layer, the surface of the Earth up to 2-3 miles in the atmosphere, and its impact on human and ecosystem health and economy. ARL conducts research on exchange, transport, dispersion, and characterization of energy, moisture, trace gases and particles, and provides data and models for weather, climate and air quality forecasts.
About – Air Resources Laboratory
NOAA's Air Resources Laboratory (ARL) studies the chemistry and physics of the boundary layer, the lowest part of the atmosphere where we live and breathe. ARL provides information and forecasts for weather, air quality, climate, and emergency management.
Atmospheric Transport: Tracers – Air Resources Laboratory
The Atmospheric Tracer Technology employed by the Air Resources Laboratory (ARL) Field Research Division (FRD), involves a small amount of a stable, non-toxic, invisible, odorless, and easily detectable substance (known as a tracer) that is released into the air.
Boundary Layer Characterization – Air Resources Laboratory
ARL uses various instruments and methods to measure and monitor the atmospheric boundary layer and its interactions with the surface. Learn about the US Climate Reference Network, mesonets, sUAS, and radio acoustic sounding system (RASS) for weather and climate research.
Atmospheric Transport and Dispersion - Air Resources Laboratory
ARL scientists study the processes and tools for modeling the transport and dispersion of harmful substances in the atmosphere. They use HYSPLIT, a widely used model developed and maintained by ARL, and conduct tracer experiments and …
Atmospheric Transport: HYSPLIT & READY - Air Resources …
READY is a system that allows users to access and display meteorological data products and to run the HYSPLIT transport and dispersion model on the NOAA Air Resources Laboratory’s web server. HYSPLIT is a widely used model for atmospheric trajectory and dispersion calculations, and READY provides real-time applications and display for various scenarios.
Research - Air Resources Laboratory
ARL conducts research on the structure and processes of the atmospheric boundary layer, which influences weather, climate and air quality. Learn about the research themes on surface-atmosphere exchange, atmospheric transport and dispersion, and boundary layer characterization.
The Air Resources Laboratory (ARL) of NOAA conducts research on atmospheric composition and emissions, such as aerosols, trace gases, and wildfires. ARL supports NOAA's weather and climate models and provides forecasts and data for air quality and health.
