Drought Monitoring with Remote Sensing Based Land Surface Phenology Applications and Validation
… understanding of the impact of drought on the lands of the Hopi Tribe and Navajo Nation, situated in the Northeastern corner of Arizona. This research explores the application of remote sensing data and geospatial tools in two studies to monitor drought impacts on vegetation productivity. In …

Land Surface Phenology of North American Mountain Environments Using the Terra Moderate Resolution Imaging Spectroradiometer
Monitoring and understanding plant phenology is becoming an increasingly important way to identify and model global changes in vegetation life cycle events. Although numerous studies have used synoptically sensed data to study phenological patterns at the continental and global scale, relatively …

A Phenological Comparison of NDVI Products within Contiguous United States
… compared relationship between SOS/EOS based on land cover. The objectives of this thesis are to: 1) compare multi-sensor NDVI data using phenological models, 2) define a strategy to merge multi-sensor NDVI products to a single phenological product without direct NDVI conversion. The spatial and …

Connecting the dots: Remote sensing of Glossy and Common Buckthorn (Frangula alnus and Rhamnus cathartica) in the Oak Openings Region of Northwest Ohio
… Thickets were identified using remotely sensed land surface phenology of buckthorn, that leafs out earlier and senesces later than native plant species. A tasseled-cap greenness index, which correlates with vegetation health and biomass, was calculated for 49 Landsat images across two time steps …

Long-term dynamics of forest phenology across the central hardwoods
… forests for access to high-quality habitat. Land surface phenology, the timing of annual growth cycles measured from remote sensing platforms, offers a potential proxy for forest ecosystem response to changing bioclimatic conditions that can be used for landscape-based wildlife conservation …

Impacts of Urban Areas on Vegetation Development Along Rural-Urban Gradients in the Upper Midwest: 2003-2012
<p>Between one-third and one-half of Earth’s land surface has been directly altered by humans, with the remainder comprised of “human-dominated ecosystems” (Vitousek et al. 2008). Earth’s population has surpassed seven billion, projected to increase by 2.5 billion by 2050 in urban areas alone …

Land Surface Phenologies and Seasonalities Using Cool Earthlight in Temperate and Tropical Croplands
… a comprehensive understanding of global cropland dynamics is critically needed. Land surface parameters derived from the passive microwave Advanced Microwave Scanning Radiometer on EOS (AMSR-E) and AMSR2 data enable monitoring of cropland dynamics and they can complement visible to near …
