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...

Spatial analysis of potato canopy nitrogen content using remotely sensed reflectance measurements

Creator:: Stangel, David E.
Abstract:: This study sought to explore the relationship between spatial scale and canopy chemistry through the use of remotely sensed videography data and total nitrogen content of potato petioles. A range of broad band spectral indices were employed along with standard red and green wavelengths to define an optimum scale or...

Remote-sensing and geographic information system techniques to map spatial variation of wheat grain yield

Creator:: Roberts, Michael C. (Michael Coy), 1951-
Abstract:: Farmers and researchers are aware of spatial variation in grain yield within farms or fields. Fertilizer management may be improved if techniques can be developed to identify grain yield variations in wheat fields. Aerial color infrared (CIR) photography was used to identify winter wheat (Triticum aestivum L.) canopy biomass variability...

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...

Identification of layered cloud occurrences from the Lidar In-Space Technology Experiment and advanced very high resolution radiometer imagery

Creator:: Stevermer, Amy J.
Abstract:: Realistic assessment of the vertical distribution of clouds, particularly the occurrence of multi-layered systems, is critical for accurate calculations of radiative transfer in general circulation models. Such information is also useful in the design and improvement of satellite retrieval techniques. Current methods for retrieving cloud properties from satellite data assume...

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...

Spatial characterization and analysis of forests in the Mount Bachelor volcanic chain, central Oregon

Creator:: Huang, Jing, 1964-
Abstract:: Forest spatial pattern is a primary interest of landscape ecology due to the relationships between spatial configuration of biotic components and ecological processes. The spatial pattern must be measured in meaningful ways so that relationships between forests and their environment can be analyzed. Aerial and satellite imageries provide ecologists a...

Land surface energy balance and surface soil moisture variation in HAPEX-MOBILHY

Creator:: Nichols, William E.
Abstract:: The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze the partition of energy and distribution of water over land surfaces. The combination of remotely sensed data and ground instrument networks over the large-scale in situ experiment allowed investigation of spatial and temporal variation of such hydrologic parameters as the...
