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 December 17, 2025, the Colorado Foothills and Front Range area experienced a severe downslope wind storm, with peak wind gusts of 60-90 MPH. Depicted here are the 10-m wind speeds and directions from the 11a MST (or 1800 UTC) forecast cycle of one of GSL's Model for Prediction Across Scales (MPAS) forecasts. This forecast, called MPAS_RRFSA, uses the first version of NOAA's Rapid Refresh Forecast System to provide information about the initial state of the atmosphere to start its forecast. These forecasts, which were just added to DESI on December 16, 2025, are developmental toward potential future versions of the Rapid Refresh Forecast System and should not be used to inform decisions related to life or property.
