Technological Advancement in Tower-Based Canopy Reflectance Monitoring: The AMSPEC-III System

Creator:: Tortini, Riccardo, Hilker, Thomas, Coops, Nicholas C., and Nesic, Zoran
Abstract:: Understanding plant photosynthesis, or Gross Primary Production (GPP), is a crucial aspect of quantifying the terrestrial carbon cycle. Remote sensing approaches, in particular multi-angular spectroscopy, have proven successful for studying relationships between canopy-reflectance and plant-physiology processes, thus providing a mechanism to scale up. However, many different instrumentation designs exist and...

Process-Based Modeling to Assess the Effects of Recent Climatic Variation on Site Productivity and Forest Function across Western North America

Creator:: Waring, Richard H., Coops, Nicholas C., Mathys, Amanda, Hilker, Thomas, and Latta, Greg
Abstract:: A process-based forest growth model, 3-PG (Physiological Principles Predicting Growth), parameterized with values of soil properties constrained by satellite-derived estimates of maximum leaf area index (LAI[subscript max]), was run for Douglas-fir (Pseudotsuga menziesii) to contrast the extent to which site growth potential might vary across western North America between a...

Potentials and limitations for estimating daytime ecosystem respiration by combining tower-based remote sensing and carbon flux measurements

Creator:: Hilker, Thomas, Hall, Forrest G., Coops, Nicholas C., Black, Andrew T., Jassal, Rachhpal, Mathys, Amanda, and Grant, Nicholas
Abstract:: Vegetation carbon uptake and respiration constitute the largest carbon cycle of the planet with an annual turnover in the order of 120 GT. Currently, neither ecosystem carbon uptake (through photosynthesis) nor ecosystem carbon release (through respiration) can be measured directly during the daytime. Instead, flux-tower measurements rely on nighttime respiration...

Virtual constellations for global terrestrial monitoring

Creator:: Wulder, Michael A., Hilker, Thomas, White, Joanne C., Coops, Nicholas C., Masek, Jeffrey G., Pflugmacher, Dirk, and Crevier, Yves
Abstract:: Free and open access to satellite imagery and value-added data products have revolutionized the role of remote sensing in Earth system science. Nonetheless, rapid changes in the global environment pose challenges to the science community that are increasingly difficult to address using data from single satellite sensors or platforms due...

Automated reconstruction of tree and canopy structure for modeling the internal canopy radiation regime

Creator:: van Leeuwen, Martin, Coops, Nicholas C., Hilker, Thomas, Wulder, Michael A., Newnham, Glenn J., and Culvenor, Darius S.
Abstract:: Understanding canopy radiation regimes is critical to successfully modeling vegetation growth and function. For instance, the vertical distribution of photosynthetically active radiation (PAR) affects vegetation growth, informative upon carbon and energy cycling. Availing upon advances in information capture and computing power, geometrically explicit modeling of forest structure becomes increasingly possible....

Remote sensing of transpiration and heat fluxes using multi-angle observations

Creator:: Hilker, Thomas, Hall, Forrest G., Coops, Nicholas C., Collatz, James G., Black, T. Andrew, Tucker, Compton J., Sellers, Piers J., and Grant, Nicholas
Abstract:: Surface energy balance is a major determinant of land surface temperature and the Earth's climate. To date, there is no approach that can produce effective, physically consistent, global and multi-decadal energy–water flux data over land. Net radiation (R[subscript n]) can be quantified regionally using satellite retrievals of surface reflectance and...

Prediction of Wood Fiber Attributes from LiDAR-Derived Forest Canopy Indicators

Creator:: Hilker, Thomas, Frazer, Gordon W., Coops, Nicholas C., Wulder, Michael A., Newnham, Glenn J., Stewart, James D., van Leeuwen, Martin, and Culvenor, Darius S.
Abstract:: We investigated the potential use of airborne light detection and ranging (LiDAR) data to predict key wood fiber properties from extrinsic indicators in lodgepole pine leading forest stands located in the foothills of central Alberta, Canada. Six wood fiber attributes (wood density, cell perimeter, cell coarseness, mature fiber length, microfibril...

Experiments on the Accuracy of a 3D Motion Capture System: A Project Report submitted to Oregon State University in partial fulfillment of the requirements for the degree of Master of Science

Creator:: Brown, Nicholas C.
Abstract:: The motion of floating objects are of importance to engineers and scientists in a range of applications. For example, in the design of ships and wave energy convertors and the study of debris mobilized by tsunamis. Measuring the movement of floating objects in the laboratory can be challenging. Six degrees...

Estimating forest productivity in the eastern Siskiyou Mountains of southwestern Oregon using a satellite driven process model, 3-PGS

Creator:: Coops, N. C. and Waring, R. H.
Abstract:: The 3-PGS (physiological principles for predicting growth using satellite data) model generates monthly estimates of transpiration, photosynthesis, and net primary production (NPP), the latter derived as a fixed proportion (0.47) of gross photosynthesis. To assess the reliability of a simplified process model (3-PGS) to predict the productive capacity of coniferous...
