An ad hoc committee will plan a workshop to bring together experts for discussions on the future of observing and modeling the boundary layer, including consideration of mature or new in situ and ground-based, airborne and satellite remote sensing technologies and cutting edge innovations that could be particularly useful in advancing understanding. Workshop participants will be asked to:

• examine our understanding of atmospheric boundary layer processes and interactions with land, ocean, and ice surfaces and science drivers, from observation, modeling, and data assimilation perspectives;
• discuss key observing and modeling gaps and the science that could be accomplished by filling those gaps;
• consider how new observing capabilities (including targeted field campaigns) can leverage the existing surface and boundary layer observational networks and where advances in satellite remote sensing could be most beneficial;
• consider frontiers in technology, innovation, and partnerships (e.g., optics and photonics sensor development) that would expand current capabilities (e.g., ground-based lidar and microwave radiometer profiles) and build on existing networks;
• discuss strategies for technology development to reduce cost and improve data quality; and
• discuss ways to foster communication between user and technology development communities to develop increased collaboration opportunities that could help rapidly advance the science.

A proceedings of the workshop will be prepared by a designated rapporteur in accordance with institutional guidelines.
