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.


In particular, 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.

New Dust Forecast Model Excels in Predicting Recent Dust Storms

December 20, 2021

December 2021 saw some regions of the US experiencing record breaking weather patterns with deadly tornados and damaging winds. An Extreme Wind Event on December 14-16 brought winds up to 100 mph to parts of southern Colorado towns such as Pueblo and Manitou Springs. Intense dust storms, sometimes called a haboob, raced across the dry plains in Colorado and Kansas to produce widespread blowing dust over much of the region.
