A Direction-Sensitive Radiation Detector for Low-Altitude, UAV-based Radiological Source Search

Creator:: Becker, Eric M. (Eric Matthew)
Abstract:: Many devices and methods for radiological searches are currently being developed, including scanning using simple detectors, mapping using large-volume detectors, and Compton imaging using 3-D position sensitive detectors. However, these devices are typically expensive and the methods used require long periods of time to generate a direction or location. The...

Properties of semitransparent upper-level clouds deduced from multispectral imagery data

Creator:: Lin, Xijian
Abstract:: A multispectral retrieval method is developed on the 100 km regional scale to extract the temperature, particle size, fractional cover and 11-μm emissivity of clouds which may be semitransparent in the infrared based on emitted radiances. The scheme utilizes the nonlinear relationship between emitted radiances when clouds are semitransparent and...

Analytical framework for modeling scale-related variabilities in remote sensing

Creator:: Chen, Chaur-fong
Abstract:: A general analytical framework was established to investigate the scale-related variabilities in remote sensing. The variabilities were studied first by investigating canopy structure, canopy interaction with light, relation between spectral reflectance and plant phenological parameters. The variabilities simulated by the plant model were compared with the actual spectral data acquired...

Photosynthesis of conifers : influential factors and potentials for remote sensing

Creator:: Yoder, Barbara J.
Abstract:: Remote sensing offers the potential for monitoring photosynthesis over large temporal and spatial scales. The purpose of this thesis is to provide information that will help to develop methods to predict photosynthesis from the light reflected by canopies. The studies focused on a simple model of canopy photosynthetic potential: Acanopy...

Microwave scattering from surf zone waves

Creator:: Catalán Mondaca, Patricio A.
Abstract:: Wave breaking in the surf zone is an important forcing mechanism on the generation of nearshore currents and in the driving of sediment transport. At the same time, wave breaking can have significant spatial and temporal variability that needs to be accounted for in the description of nearshore processes. Remote...

Bright air : geoprocessing thermal imagery to map the nocturnal dynamics of the boundary layer in a mountain valley

Creator:: Johnson, Christopher
Abstract:: A thermal infrared (TIR) camera is used to remotely sense the foliage temperature in a mountain valley. The foliage temperature is used as a proxy for air temperature and can be used to study and map the dynamics of the nocturnal, weak-wind boundary layer in this valley. All radiative flux...

Estimating the in situ Stratification via Remotely-sensed Internal Wave Speeds

Creator:: Fang, Chufan
Abstract:: This work investigates a methodology for estimating the ocean stratification gradient based on high-resolution, in space and time, remote sensing observations of internal wave propagation speeds. The internal wave speed observations were collected using a shore-based, X-band marine radar and the ocean vertical density profiles were collected simultaneously from an...

Spatial Patterns of Chemical Weathering at the Basal Tertiary Nonconformity in California from Multispectral and Hyperspectral Optical Remote Sensing

Creator:: Sousa, Francis J. and Sousa, Daniel J.
Abstract:: Visible through shortwave (VSWIR) spectral reflectance of the geologic units across the basal Tertiary nonconformity (BTN) is characterized at three spatially disparate locations in California. At two of these sites, location-specific spectral endmembers are obtained from AVIRIS imaging spectroscopy and linear spectral mixture models are used to visualize spatial patterns...

Using Satellite Imagery to Count Nesting Albatross from Space

Creator:: Dolliver, Jane E.
Abstract:: One fundamental concern in conservation biology is species abundance. For many taxa, however, these data are costly to obtain via direct observation and thus limited in geographic or temporal scope. Very high-resolution satellite imagery provides a means to address these limitations and provide remotely-sensed counts of large, colonial species. We...

Water management in the North Deschutes unit irrigation district : geographic perspectives and remote sensing applications

Creator:: Nellis, M. Duane
Abstract:: The North Unit irrigation District of Central Oregon, a water project developed under the guidelines of the Bureau of Reclamation, is characterized by limited water and the need for efficient utilization and control of the irrigation system. To manage the limited water resource, irrigators need a timely and economical method...
