The 23^rd Symposium on Boundary Layers and Turbulence (BLT), sponsored by the American Meteorological Society (AMS), and organized by the AMS Committee on Boundary Layers and Turbulence, was held 11–15 June 2018 at the Renaissance, Oklahoma City hotel, in Oklahoma City, Oklahoma, USA. 

The conference was held in conjunction with AMS 21^st Conference on Air-Sea Interaction (ASI). Joint sessions were held on topics associated with renewable energy, trace gas exchange, coastal and high-latitude environments.

Papers and posters were invited on all subjects dealing with atmospheric boundary layers and turbulence, including observational, modeling, theoretical, and applied studies. In particular, we dedicated sessions for the following themes:

• Boundary layer processes, observations and modeling related to renewable energy applications (Joint with ASI)
• Exchange of trace gases (CO2, H2O, etc.) between the land/sea surface and the boundary layer (Joint with ASI)
• The coastal environment (Joint with ASI)
• High latitude air-sea interaction, including air-sea-ice interaction (Joint with ASI)
• Boundary layer clouds
• Modeling and observations in heterogeneous and/or complex terrain
• Modeling and observations in urban areas
• Modeling and observations over vegetated canopies
• Boundary layer parameterizations in models at all scales
• Theoretical and practical issues associated with multi-scale simulations
• Unsteady boundary layer behavior
• Recent field experiments (WFIP 2, Perdigao, LABLE, etc.)

Participants with additional suggestions for general, special, or joint sessions were encouraged to contact the program chairpersons.

A field trip to the National Weather Center in Norman was arranged for interested participants. An alternative option was to visit the Atmospheric Radiation Measurement (ARM) Program’s Southern Great Plains (SGP) site.

The $95 abstract fee includes the submission of your abstract, the posting of your extended abstract, and the uploading and recording of your presentation, which is archived on the AMS website.

The BLT conference hosted a student competition and award exemplary poster and oral presentations. Students were asked at the time of the abstract submission if they wanted to be considered for awards or travel support, and asked to submit a note of justification for funds and provide a letter of support from their primary advisor. 

Authors of accepted presentations were notified via e-mail by mid-March 2018.  All abstracts, extended abstracts and presentations are available on the AMS website at no cost.
