RISRay-Tracing Method for Deriving Terrestrial Laser Scanner Systematic Errors
Publisher: American Society of Civil Engineers
Modeling Terrestrial Laser Scanner Data for Precise Structural Deformation Measurement
Publisher: American Society of Civil Engineers
Abstract: A modeling strategy has been developed that permits coarse-precision terrestrial laser scanner observations to be used to accurately measure vertical deflections of deforming beams. The model is developed from fundamental ...
Remotely Sensing the Earth’s Atmosphere Using the Global Positioning System (GPS)—The GPS/MET Data Analysis
Publisher: American Meteorological Society
Abstract: The Global Positioning System/Meteorology (GPS/MET) project is an active satellite-to-satellite remote sensing experiment using the radio occultation technique. Due to the atmospheric index of refraction and gradient of ...
Error Models and Propagation in Directly Georeferenced Terrestrial Laser Scanner Networks
Publisher: American Society of Civil Engineers
Abstract: Cultural heritage recording and engineering surveying are prime applications for terrestrial laser scanners (TLSs) because of the high spatial resolution, high accuracy, and fast data capture rates this technology offers. ...
Large Temperature Fluctuations due to Cold-Air Pool Displacement along the Lee Slope of a Desert Mountain
Publisher: American Meteorological Society
Abstract: arge temperature fluctuations (LTFs), defined as a drop of the near-surface temperature of at least 3°C in less than 30 min followed by a recovery of at least half of the initial drop, were frequently observed during the ...
Simulated and Observed Surface Energy Fluxes and Resulting Playa Breezes during the MATERHORN Field Campaigns
Publisher: American Meteorological Society
Abstract: eather Research and Forecasting (WRF) Model simulations of the autumn 2012 and spring 2013 Mountain Terrain Atmospheric Modeling and Observations Program (MATERHORN) field campaigns are validated against observations of ...
Coastal Wind and Turbulence Observations during the Morning and Evening Transitions over Tropical Terrain
Publisher: American Meteorological Society
Abstract: AbstractData collected during a multiyear, wind-resource assessment over a multi-land-use coastal environment in Belize are used to study the development and decay of wind and turbulence through the morning and evening ...
Small Parshall Flume Rating Correction
Publisher: American Society of Civil Engineers
Abstract: The Parshall flume is one of the most widely used instruments for measuring water discharge in open channels. However, field observations indicate that because the flume is subjected to field and climatic conditions, it ...
Riprap Sizing for ARS‐Type Low‐Drop Stilling Basins
Publisher: American Society of Civil Engineers
Abstract: The Agricultural Research Service (ARS)‐type low‐drop structure was developed and utilized to stabilize incising channels in northern Mississippi. The structure consists of a sheet pile stabilizer weir and stilling basin ...
Structural Deflection Measurement with a Range Camera
Publisher: American Society of Civil Engineers
Abstract: Range cameras offer great potential for the measurement of structural deformations because of their ability to directly measure video sequences of three-dimensional coordinates of entire surfaces, their compactness, and ...
