Who we are

In a world where technology and Earth system science are advancing rapidly, the Global Systems Laboratory (GSL) stands at the forefront of atmospheric research The core of GSL's culture is a dynamic and forward-thinking spirit that drives our investment in people, partnerships, and organizational performance. GSL is a space where innovation and science converge in a hybrid and collaborative environment.

GSL is one of ten NOAA Research Laboratories and is located in Boulder, Colorado. Our research improves environmental prediction models, develops state-of-the-science decision support tools, visualization systems, and uses high-performance computing technology and artificial intelligence research to support a Weather-Ready Fire-Ready Nation.

Our Research Serves The Nation

The research we do improves weather data, forecasts, and computing techniques used by industry, decision-makers, and stakeholders. Our work makes the nation's operations safer and more efficient, helps protect lives and property, and promotes economic prosperity.

Public Safety

GSL's models and technology help emergency managers respond to weather threats quickly.

Aviation

Our tools help the Federal Aviation Administration (FAA) reduce air traffic delays and increase safety.

Energy

GSL's weather models facilitate planning for variability in the energy industry.

Fire Weather

Decision support systems and smoke models developed by GSL help with wildfire operations.

Our Latest Projects

GSL's HRRR-Smoke Model predicts how the weather impacts smoke movement and how much the smoke could reduce visibility and air temperatures. The HRRR Smoke Model is a component of the High-Resolution Rapid Refresh weather model that transitioned to NOAA and National Weather Service operations on December 2, 2020.
