Infrared Quantitative Imaging Velocimetry (IR-QIV) data supporting Schweitzer & Cowen, 2021, WRR
(2021-07-07)This data set contains infrared images and velocity measurements collected at two sites on the Sacramento River, and one of its tributaries, near Sacramento, California, USA, in November 2017. Details on the data collection ... -
Postprocessed large-eddy simulation data from: Connection between mass flux transport and eddy diffusivity in convective atmospheric boundary layers
(2021-05-06)Turbulence parameterizations for convective boundary layer in coarse-scale atmospheric models usually consider a combination of the eddy-diffusive transport and a non-local transport, typically in the form of a mass flux ... -
Code and data from: Gaussian Process Regression for Estimating EM Ducting Within the Marine Atmospheric Boundary Layer
(2019-11-26)We show that Gaussian process regression (GPR) can be used to infer the electromagnetic (EM) duct height within the marine atmospheric boundary layer (MABL) from sparsely sampled propagation factors within the context of ... -
Code and data from: Characterizing Evaporation Ducts Within the Marine Atmospheric Boundary Layer Using Artificial Neural Networks
(2019-10-22)Abstract: We apply a multilayer perceptron machine learning (ML) regression approach to infer electromagnetic (EM) duct heights within the marine atmospheric boundary layer (MABL) using sparsely sampled EM propagation data ... -
Chapter 4: Basic Concepts and System Design
(2019)All airborne lidar bathymeter (ALB) systems locate the bottom of a water body by tracking the progression of a short light pulse from its initial contact with the water surface through its interaction with the bottom. The ... -
Chapter 3: Environmental Optical Properties
(2019)When the lidar pulse is transmitted out of the ALB system, it interacts with various environmental regions from the time of transmission until the pulse is reflected from the seafloor and received back at the ALB detector. ... -
Chapter 2: History
(2019)The early years of laser hydrography have been traced by Guenther (1985). His review tracks the development of laser hydrography, now more commonly known as Airborne Laser Bathymetry (ALB), from the earliest theoretical ... -
Reflections and the focusing effect from an ideal three-dimensional rough surface
(2006-03-04)An analytical expression for higher-order reflectances from a shallow-water homogeneous ocean bottom modeled as an egg-carton surface is presented. Roughness of this ideal surface is expressed as the amplitude-to-length ... -
The off-specular peak and polarisation effects of an undulating underwater suface
(2006-03-03)Periodic undulations are used to describe underwater bottom roughness. An expression of the bi-directional reflectance distribution function (BRDF) is given that is dependent on the given roughness metric. Highlights include ... -
Backscattering anisotropy near $180^{\circ}$: an indication of particle size and shape
(2006-03-01)By modelling the single scattering of particles in the exact backward direction ($180^{\circ}$) and $5^{\circ}$ around, the field of view of an instrument measuring backscattering is simulated. Calculations of the scattering ...
