About EOL

EOL Mission

The Earth Observing Laboratory (EOL) is NSF NCAR’s end-to-end observational enterprise, dedicated to advancing research and understanding of the Earth’s atmosphere. As one of NSF NCAR’s seven laboratories, EOL brings together scientific leadership, technical expertise, advanced observing capabilities, and operational experience to support atmospheric research from planning and development through field deployment, data delivery, and scientific discovery.

EOL manages and deploys a major share of NSF’s Lower Atmosphere Observing Facilities (LAOF), supporting research projects of diverse scales and complexity. We work with universities, NSF NCAR, government agencies, and the broader research community to design and conduct field campaigns, operate sophisticated observing systems, and deliver high-quality atmospheric observations. At the same time, EOL advances the capabilities available to researchers by developing and incorporating new technologies into observing systems and instrumentation.

EOL serves as a hub for atmospheric observations, bringing together people, technology, and data to advance scientific understanding. Our capabilities span a broad range of observing systems, including radars, lidars, profilers, in-situ sensors, and airborne instrumentation, supported by expertise in engineering, project management, field operations, data services, and scientific collaboration.

Key Initiatives

EOL advances its mission through four interconnected areas of expertise and capability: Development, Deployment, Data Services, and Discovery. Together, they span the path from developing new observing capabilities, to collecting and stewarding high-quality data, to enabling the scientific community to use those observations to advance understanding of the Earth system.

Development

Building the capabilities science needs next.
EOL develops, adapts, and integrates observing technologies to address emerging scientific challenges. Our engineers, scientists, and technical specialists design, build, test, and improve instruments, platforms, and measurement systems in close partnership with the research community.

Deployment

Putting advanced observing capabilities to work in the real world.
For nearly six decades, EOL has planned and supported complex field campaigns across the globe. We provide the facilities, instruments, technical expertise, and operational leadership needed to collect high-quality observations wherever the atmosphere needs watching.

Data Services

Turning observations into accessible, usable scientific data.
EOL manages the data lifecycle from collection and quality control through delivery, stewardship, and long-term access. We provide data systems, archives, tools, and expertise that enable researchers to find, understand, analyze, and reuse atmospheric observations.

Discovery

Enabling scientific discovery and the next generation of researchers.

EOL connects observations, expertise, and people to expand what researchers can learn about the atmosphere and Earth system. We support the broader scientific community through collaboration, education, internships, training, and outreach, helping researchers and the next generation of scientists, engineers, and technical professionals make use of atmospheric observations and advance Earth system science.
