    Solar radiation at the Earth's surface: Its calculation and inference from satellite imagery

    Get PDF
    Physical and empirical models for calculation of insolation on a horizontal surface are described. Calculation of the spectral components of insolation and the calculation of the integrated values using wavelength-averaged values, ignoring aerosol effects, are discussed. Empirical models for determining insolation from meteorological data under clear and cloudy skies are described. The influence of hourly and daily global solar radiation from GOES satellite images is illustrated. Data acquisition methods for the Great Plains experiment, the determination of cloud free brightness levels, and determination of cloud parameters and target brightness are considered. The use of two and seven satellite images per day resulted in insolation determinations having a standard error of less then 10% of the mean. Use of only one image per day resulted in a standard error of about 20% of the mean

    The paleomagnetism of the Upper Ordovician Fairview Formation

    Get PDF
    A paleomagnetic study was conducted involving the Upper Fairview (Upper Ordovician, Maysvillian) Formation and Lower Fairview Formation. The purpose of this study was to determine the possibility of measuring the geomagnetic polarity reversals occurring in paleozoic limestones. This thesis is primarily concerned with, and concentrates on, the latter twenty one feet and its results. For information concerning the remaining section, see Musser (1977)

    EVALUATING TRANSIT SYSTEMS IN A UNIVERSITY ENVIRONMENT THE CLEMSON UNIVERSITY CASE STUDY

    With the economy in a slow recovery, enrollment in higher education is increasing. This means that universities across the country must accommodate these new students, their vehicles, and local transportation needs. Campus setting and ambiance is a treasured quality on a university campus resulting in the approval of additional surface lots and parking garages being difficult or restricted. To combat the increased number of single occupancy vehicles, universities are developing and encouraging the use of multimodal transportation by providing pedestrian, bicycle, and public transportation facilities along with providing users with the information necessary to make the optimal modal choice (Boyles, 2006). This research developed a framework to evaluate transit in the context of mobility currently on a university campus. The framework includes a process that any university can utilize to evaluate its current and future transit efficiency levels and identify solutions through an integrated process of planning, operations, and performance monitoring. Clemson University\u27s campus in Clemson, South Carolina serves as a case study for the test application of this process. This study evaluates Clemson University\u27s performance in providing adequate transportation options to the university community in comparison with similar universities. Customer satisfaction surveys are used to determine deficiencies from the user\u27s perspective. Traffic simulations and a matrix alternative analysis have evaluated several alternatives developed through integrating the results of transit capacity surveys, user surveys, and considerations for pedestrian and bicycle traffic to create seamless operations and optimal function of all transportation modes available. The case study presented in this thesis can serve as a guide to university campuses beginning to have significant mobility problems. It also provides an insight into the institutional or organizational structures that facilitate efficient, high-quality transportation services, which can guide universities to pursue structural or policy changes to improve mobility. Although the process is tailored for small &ndash or medium &ndash sized universities outside of urban areas, the evaluation framework can be customized for use at any university regardless of its size or location
