A Phenological Comparison of NDVI Products within Contiguous United States
… order to evaluate the difference and similarity of NDVI records from the three sensors, I used EPA Eco-region frameworks to determine the average annual Start of Season (SOS) and End of Season (EOS) of Contiguous United States, and analyzed dates among datasets. In addition, I created 1127 sample …

Land Surface Phenology of North American Mountain Environments Using the Terra Moderate Resolution Imaging Spectroradiometer
… on characterizing the land surface phenology of specific ecosystems. Mountain environments provide excellent examples of how variations in topography, elevation, solar radiation, temperature, and spatial location affect vegetation phenology. High elevation biomes cover twenty percent of the …

Reconstructing NDVI Time Series from Landsat and MODIS and Developing a Species-Specific Validation Dataset for Vegetation Classification in Frontenac Provincial Park
Understanding the timing of vegetation green-up and species composition in forests is critical for monitoring ecosystem dynamics and assessing how forests are shifting under climate change. This thesis investigates spring start of season (SOS) using remote sensing and develops a field-based species …

An assessment of the onset of summer rainy season in Southern Africa - case study of Botswana
The economies of most Sub-Saharan African countries are linked to the onset, reliability and performance of seasonal rainfall. Failure of seasonal rains may signal food deficits or worse. Farmers, water conservationists and government bodies responsible for food security, all have an interest in …

Analysis of Dryland Forest Phenology using Fused Landsat and MODIS Satellite Imagery
… investigated the practicality and expediency of applying remote sensing data fusion products to the analysis of dryland vegetation phenology. The objective of the first study was to verify the quality of the output products of the spatial and temporal adaptive reflectance fusion method …

Allergenic pollen concentrations in the United Kingdom
This study investigates the variations in the start and severity of the grass and birch pollen seasons at a network of sites in the United Kingdom. Daily grass and birch pollen concentrations have been monitored during the course of the study (1992-1994) at the University of North London site. …

Fine Characterization of Leafing Phenology in the Brazilian Atlantic Forest by Optical and Microwave Remote Sensing
… remain among the most poorly understood elements of land surface models, especially with regard to their seasonal dynamics. For instance, in seasonally dry forests, the pattern of the annual green-up in their canopies closely follows annual patterns of rainfall. The same, however, does not occur …

Biomechanical measures of lower limb variability, and prediction of non-contact knee injuries risk factors in male athletes
Introduction: Football is one of the most popular sports played globally. Male players constitute 82% of football players around the world. As the number of football players increases, we expect more sports injuries to occur. Knee ligament injuries, such as Anterior Cruciate Ligament (ACL), are …

Isokinetic muscular strength and performance in youth football : relationships with age, seasonal variation and injury
The primary aim of the current project was to investigate the isokinetic muscular strength and performance of elite male youth footballers, and the relationships with age, seasonal variation and injury. A secondary aim was to use the information gathered to target muscle strain injury prevention …
