About ARL

The Air Resources Laboratory’s (ARL) 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. ARL’s research focus is on the surface of the earth from a few feet below the soil up to 2-3 miles in the atmosphere (aka the boundary layer), which has a direct impact on people’s health and safety, business, and the environment. ARL studies the physical and chemical processes that occur in the boundary layer, on time scales spanning a few hours to several years.

ARL studies the mixing, exchange, and transformation of energy, moisture, trace gases, and particles, and contributes inputs to meteorological models and forecast operations that are vital in improving weather, climate and air quality forecasts. Primary applications include emergency response, homeland security, air quality, weather forecasts and climate outlooks, and commerce and transportation. ARL’s vision is to effectively protect people, the environment, and commercial activities from atmospheric risks using the best available scientific understanding of boundary layer processes.

AEROMMA – Measuring pollution from megacities to marine areas

September 7, 2023

This summer, NOAA Air Resources Laboratory (ARL) researchers joined together with experts from numerous other institutions and federal agencies to investigate the causes of poor air quality. Their research campaign will investigate not only anthropogenic, or human caused emissions, but also biological sources of emissions that alter the atmospheric chemistry and composition and impact air quality and climate over North America.

Field Notes: U.S. Climate Reference Network Alaskan Site Installations

August 25-30, 2023

One of ARL’s main programs is to install, maintain and update numerous U.S. Climate Reference Network (USCRN) installations. Most USCRN stations are remote, and that is by design to remove the influence of cities, industry and human activity. Some are deep in wildlife refuges, and traveling to each site annually often presents unexpected challenges.

Solar Array installation begins at Galena.
