  • A-posteriori analysis of surface energy budget closure to determine missed energy pathways

    Creator:
    Higgins, Chad W.
    Abstract:
    The residual of the surface energy budget is represented as the linearized sum of energy losses due to storage, advection and flux underestimation. Individual contributions to the residual can be quantified through constrained multiple linear regression which identifies the site specific processes that are responsible for the lack of energy...

  • Pollinator-Focused Solar: Observations of Plant-Pollinator Interactions in the Agrivoltaic Understory

    Creator:
    Graham, Maggie
    Abstract:
    Habitat for pollinating insects is declining, which is a concern for agricultural communities that rely on pollination services. Meanwhile, solar energy development is increasing as communities seek to source energy renewably. Land under solar panels is traditionally unused, so some communities are planting pollinator habitat under solar panel canopies to...

  • Addressing Data Resolution in Precision Agriculture

    Creator:
    Kelley, Jason
    Abstract:
    Irrigated agriculture constitutes the greatest consumptive water use globally, so that irrigation efficiency measures are an important part of global efforts to best utilize this limited resource. However, greater irrigation efficiency must be achieved while simultaneously maintaining or increasing crop yields and farming profitability. Incremental water use decisions are made...

  • Lasers in the Sky : Distributed Temperature Sensing and a Micro-Meteorological Approach to Quantifying Evapotranspiration

    Creator:
    Predosa, Robert
    Abstract:
    Lower atmospheric flux measurements are a difficult subset of atmospheric data to accurately collect. The interplay of cost, precision, specialty, resolution and repeatability compound an already difficult experimental problem. In response to this, a new, novel instrumentation approach to measuring within the atmospheric boundary layer (ABL) is introduced. The combination...

  • The influence of solar panels on local hydrology and plant ecology

    Creator:
    Hassanpour, Elnaz
    Abstract:
    Photo voltaic solar energy is a clean source of energy with much lower carbon footprint than other sources. However, the vast land requirements of solar energy arrays may make installation impractical when available land is better suited for other purposes. The goal of this research was to investigate changes to...

  • Lamb Growth and Seasonal Herbage Production from Simple, Diverse, and Legume Pastures Established in an Agrivoltaic System

    Creator:
    Andrew, Alyssa C.
    Abstract:
    Agrivoltaic systems promote dual use of land by combining solar energy and agricultural production. Grazing sheep in these systems is popular but research on intentionally designed pastures to increase production is lacking. This study seeks to compare the herbage growth and lamb production in simple, diverse, and legume pasture mixes...

  • Leveraging the Food-Energy-Water Nexus for Planet Resilience

    Creator:
    Steadman, Casey L.
    Abstract:
    We have sufficient evidence that our historical management of natural resources is not sustainable. Food production is stagnating or declining. Nonrenewable energy sources on which the energy sector has historically depended are being rapidly depleted. Water resources, for which the energy and food sectors compete, are being depleted and impaired....

  • Measuring Tomato Production and Water Productivity in Agrivoltaic Systems

    Creator:
    Al-agele, Hadi A.
    Abstract:
    Growing populations and industrialization rates across the world are leading to increased food and energy demand. The challenge of meeting this demand while also mitigating climate change impacts serves as a driving force for the development of renewable energies technologies. This study focuses on the role of Agrivoltaic systems in...

  • Environmental Impacts of Renewable Energy (solar and wind) on Water, Food and Energy Nexus

    Creator:
    Hassanpour Adeh, Elnaz
    Abstract:
    Rapid increasing of renewable energies and the knowledge about their environmental effects are very limited. As a result, the renewable energies (e.g. solar or wind energies) will play a vital role in the future because it is well accepted by environmental friendly industries. This dissertation presents the modeling, data analysis...

  • The field edge flux paradox

    Creator:
    Barr, Colleen M.
    Abstract:
    Precision irrigation has made spatially explicit water management a reality. However, detailed knowledge about the spatially variable evapotranspiration is often unavailable. One example location where we can begin to understand the impact of spatial variability on evapotranspiration is at the field edge, which contains a sharp discontinuity in surface conditions....
