About the Organization:

Formed in 2005, the Earth Observing Laboratory (EOL) is one of the seven laboratories of NCAR, the National Science Foundation’s Federally Funded Research and Development Center. EOL’s mission is to provide leadership in observing facilities, field project support as well as research and data services needed to advance the scientific understanding of the Earth system. EOL manages the majority of NSF’s Lower Atmosphere Observing Facilities (LAOF) and deploys them in support of observational field campaigns, ranging from single investigator projects to large complex campaigns that involve multiple investigators, agencies, and platforms, nationally and internationally. EOL deploys its systems for research by scientists from universities, NCAR, and government agencies, as well as for education. An integral part of EOL’s mission is to develop the next generation of LAOF and to provide management and archiving of data from past supported campaigns. In order to ensure progress in the atmospheric sciences, EOL supports a wide-range of research areas within the Earth system science, ranging from microscale to mesoscale to climate process studies, and employs LAOF platforms and systems that reach from the surface of the Earth to the lower stratosphere and beyond.

 

Top Reasons to Work with Us:

EOL’s In-Situ Sensing Facility (ISF) provides measurements made directly in the environment as well as profiling measurements of the lower atmosphere. Measurements are made in-situ at the earth’s surface, on towers, on balloons, and on packages dropped from aircraft. Profiling measurements are made using vertically pointing radar, lidar and acoustic sensors. ISF aims to serve the advanced observational needs of the atmospheric science community by providing a flexible, state-of-the-art backbone measurement capability applicable to a wide range of experimental needs – emphasizing advanced sensor capabilities, sensor integration, system mobility, and the ability to deploy to remote or difficult locations.
