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...

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...

Identification of irrigation practices using photographic and optical-mechanical scanning remote sensing techniques

Creator:: Naim, Shamim
Abstract:: Irrigation is essential for profitable agriculture in the western United States. It is the largest consumer of water and power in Oregon. Conflicting uses of water and power and their scarcity demands judicious planning for allocation of these resources. Creditable baseline data are not only needed for irrigated crop acreages,...

Depth estimation and frontal imaging via X-band marine radar

Creator:: Honegger, David Andrew
Abstract:: This dissertation focuses on two core aspects of remote sensing: (a) interpretation of the remotely sensed data to identify and characterize sea surface features of interest, and (b) the quantitative analysis of previously characterized features to produce robust estimates of geophysical variables. Specifically, these aspects are addressed in the context...

Remote measurements of waves and currents over complex bathymetry

Creator:: Chickadel, Carmine C. (Carmine Christopher)
Abstract:: Waves are the primary input of energy in the nearshore region, and together with the currents forced through the transfer of momentum that occurs during the wave breaking process they are the principal mechanism for sediment transport in the nearshore. The basic physics of waves and currents are thought to...

Properties of low-level marine clouds as deduced from advanced very high resolution radiometer satellite observations

Creator:: Chang, Fu-Lung
Abstract:: A radiation model was developed for retrieving cloud visible optical depth, droplet effective radius, and cloud top emission temperature using AVHRR satellite observations at 0.63, 3.7, and 11 μm. The model was used to determine the sensitivity of the retrieved properties to various approximations often employed in such retrievals. Droplet...
