title = "Exploring Influences of Shallow Topography in Stable Boundary Layers The SAVANT Field Campaign",
abstract = "Stable boundary layers are still a relatively problematic component of atmospheric modeling, despite their frequent occurrence. While general agreement exists that Monin–Obukhov similarity is not applicable in the stable boundary layer (SBL) due to the nonhomogeneous, nonstationary flow, no universal organizing theory for the surface SBL has been presented. The Stable Atmospheric Variability and Transport (SAVANT) field campaign took place in the fall of 2018 to explore under what conditions shallow drainage flow is generated. The campaign took place in an agricultural setting and covered the period of both pre- and postharvest, allowing for not only a basic exploration of the boundary layer but also a robust dataset for applied agricultural understanding of aerosol dispersion and impacts of changes in surface cover on drainage flows. This article provides a description of the field campaign. Examples of publicly available data products are presented, as well as examples of shallow drainage flow and corresponding lidar measurements of dispersion. Additionally, the field campaign was used to provide educational opportunities for students from several disciplines, and the outcomes of these joint educational ventures are discussed as models for future collaborations.",

We thank CTEMPs, funded by the National Science Foundation (EAR Awards 18-32109 and 18-32170), for timely and effective provision of experimental design support, logistical support, and equipment for the project. During SAVANT, a course of students from the University of Wisconsin visited the SAVANT field campaign in Illinois. “Meteorological Measurements” is an existing course at UW with an established history of field trips, so institutional buy-in and precedence existed. The trip was funded through an NSF supplemental award, in which UW unmanned aerial vehicles (UAV) based forward looking infrared (FLIR) instrumentation available from the University of Wisconsin could enhance the science objectives of SAVANT. The students traveled from Wisconsin to Illinois for a 2-night trip in October. During their stay, they deployed additional instruments on their own, participated in an IOP, and networked with SAVANT and NCAR personnel. After returning to UW, they authored a collaborative class paper reporting their results. This experience directly increased the course{\textquoteright}s learning objectives of “providing exposure to more advanced surface layer instrumentation” and “improved teamwork skills by participating in a hands-on, team-based field project” (A. Desai 2019, personal communication).",
