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.

DESI Digest: Turning Forecasts into Visual Insight

DESI Digest showcases powerful visualizations from NOAA's Dynamic Ensemble-based Scenarios for IDSS (DESI) project. These quick, impactful videos turn complex forecasts into clear insights that support emergency managers, forecasters, and the public.

Check back often for fresh, scenario-driven updates on the nation's evolving weather.

On Friday, January 16, 2026, high winds spread over much of the Northern and Central Great Plains, with widespread wind gusts of 50-70 MPH across eastern Wyoming and Colorado. At the same time, isolated snow squalls developed across southern South Dakota and northern Nebraska, causing locally hazardous driving conditions. This animation from the 0000 UTC January 16, 2026 forecast cycle of GSL's experimental Model for Prediction Across Scales-based forecast system initialized from the pre-operational version 1 of NOAA's Rapid Refresh Forecast System depicts instantaneous 10-m wind gusts (barbs and semi-transparent shading) and 1-h predicted snowfall (opaque shading). This forecast accurately captured the timing, location, and severity of these high-impact weather events.
