Sodars are widely used to monitor boundary layer conditions, and the BLISS research group at OU manages two sodars. Sodars can provide information about the boundary layer wind profile, as well as the thermodynamic structure of the atmosphere.

A time-series sodar simulator capable of ingesting large eddy simulation data has been developed. The sodar simulator follows the same method as an operational sodar to reproduce output parameters that would be generated by a sodar operating within the conditions represented by the LES. The sodar simulator operating parameters can be tuned to mirror existing systems or test new configurations or signal processing techniques, and the simulator can be placed anywhere within the LES domain, including overlapping with other virtual sampling instruments.

In this seminar, the algorithmic structure of the sodar simulator will be presented. A case study testing the sodar simulator on large eddy simulation output representing the convective boundary layer will be presented and discussed.

For accommodations based on disability, or more details, please call 325-6561. All visitors without NOAA or University of Oklahoma identification must register at the registration desk on arrival. Visitor parking is available for all University visitors. However, faculty/staff/students must have a current multi-purpose parking permit. Additional parking is available at the Lloyd Noble Center (LNC) for those individuals who do not have a parking permit. You do not need a permit to park in one of 1,200 spaces reserved for CART bus riders, although you must ride the CART shuttle to park in the reserved area. This area is on the north central side of the Lloyd Noble Center. Elsewhere at the LNC, permits are required.

The University of Oklahoma is a smoke-free / tobacco-free campus.
