RISRetrieval of Urban Boundary Layer Structures from Doppler Lidar Data. Part II: Proper Orthogonal Decomposition
Publisher: American Meteorological Society
Abstract: The proper orthogonal decomposition technique is applied to 74 snapshots of 3D wind and temperature fields to study turbulent coherent structures and their interplay in the urban boundary layer over Oklahoma City, Oklahoma. ...
Scopes and Challenges of Dual-Doppler Lidar Wind Measurements—An Error Analysis
Publisher: American Meteorological Society
Abstract: ulsed Doppler lidars are powerful tools for long-range, high-resolution measurements of radial wind velocities. With the development of commercial Doppler lidars and the reduction of acquisition costs, dual-Doppler lidar ...
Retrieval of Urban Boundary Layer Structures from Doppler Lidar Data. Part I: Accuracy Assessment
Publisher: American Meteorological Society
Abstract: Two coherent Doppler lidars from the U.S. Army Research Laboratory (ARL) and Arizona State University (ASU) were deployed in the Joint Urban 2003 atmospheric dispersion field experiment (JU2003) held in Oklahoma City, ...
Atmospheric Data Visualization in Mixed Reality
Publisher: American Meteorological Society
Abstract: ixed reality taps into intuitive human perception by merging computer generated views of digital objects (or flow fields) with natural views. Digital objects can be positioned in 3D space and can mimic real objects in the ...
Flow around a Complex Building: Experimental and Large-Eddy Simulation Comparisons
Publisher: American Meteorological Society
Abstract: A field program to study atmospheric releases around a complex building was performed in the summers of 1999 and 2000. The focus of this paper is to compare field data with a large-eddy simulation (LES) code to assess the ...
Three-Dimensional Wind Retrieval: Application of MUSCAT to Dual-Doppler Lidar
Publisher: American Meteorological Society
Abstract: During the field campaign of the Terrain-induced Rotor Experiment (T-REX) in the spring of 2006, Doppler lidar measurements were taken in the complex terrain of the Californian Owens Valley for six weeks. While fast ...
Flow around a Complex Building: Comparisons between Experiments and a Reynolds-Averaged Navier–Stokes Approach
Publisher: American Meteorological Society
Abstract: An experiment investigating flow around a single complex building was performed in 2000. Sonic anemometers were placed around the building, and two-dimensional wind velocities were recorded. An energy-budget and wind-measuring ...
Nocturnal Low-Level-Jet-Dominated Atmospheric Boundary Layer Observed by a Doppler Lidar over Oklahoma City during JU2003
Publisher: American Meteorological Society
Abstract: Boundary layer wind data observed by a Doppler lidar and sonic anemometers during the mornings of three intensive observational periods (IOP2, IOP3, and IOP7) of the Joint Urban 2003 (JU2003) field experiment are analyzed ...
The METCRAX II Field Experiment: A Study of Downslope Windstorm-Type Flows in Arizona’s Meteor Crater
Publisher: American Meteorological Society
Abstract: he second Meteor Crater Experiment (METCRAX II) was conducted in October 2013 at Arizona?s Meteor Crater. The experiment was designed to investigate nighttime downslope windstorm?type flows that form regularly above the ...
The Canopy Horizontal Array Turbulence Study
Publisher: American Meteorological Society
Abstract: y Horizontal Array Turbulence Study (CHATS) took place in spring 2007 and is the third in the series of Horizontal Array Turbulence Study (HATS) experiments. The HATS experiments have been instrumental in testing and ...
