About EOL

EOL Mission

The Earth Observing Laboratory (EOL) is NCAR’s end-to-end observational enterprise, dedicated to facilitating research of the Earth’s atmosphere. As one of NCAR’s seven laboratories, EOL leverages technology and expertise to take a leading role in observational research, field project support, and data collection.

EOL plays an important role in managing and deploying the majority NCAR’s Lower Atmosphere Observing Facilities (LAOF) across projects of diverse scales and complexities. Our team deploys a range of instruments and observing facilities to support field campaigns, supporting researchers from universities, NCAR, and government agencies.   Additionally, EOL is committed to advancing research frontiers by incorporating new technologies into instrumentation.

At the heart of NSF's atmospheric research community, EOL serves as a hub for collecting observational data and disseminating knowledge on instrumentation, measurements, and scientific observations. EOL features a wide array of instruments and equipment, including radars, lidars, profilers, in-situ sensors, and airborne instrumentation, fostering collaborative analysis and furthering scientific understanding.
