  • Hybrid computational voxelization using the graphics pipeline

    Creator:
    Rauwendaal, Randall
    Abstract:
    This thesis presents an efficient computational voxelization approach that utilizes the graphics pipeline. Our approach is hybrid in that it performs a precise gap-free computational voxelization, employs fixed-function components of the GPU, and utilizes the stages of the graphics pipeline to improve parallelism. This approach makes use of the latest...

  • Overestimation of cloud cover in the MODIS cloud product

    Creator:
    Schuetz, Andrea M.
    Abstract:
    The operational processing of MODIS imagery to produce the MOD06 cloud product is based on the assumption that cloudy 1-km pixels are overcast. This assumption is examined using a partly cloudy pixel retrieval scheme, which allows for fractional cloud cover within the 1-km pixels. Cloud flags attached to 250-m MODIS...

  • Voxel based indirect illumination using spherical harmonics

    Creator:
    Rauwendaal, Randall
    Abstract:
    Realistic (ideally photorealistic) real-time rendering has remained an elusive goal in computer graphics. While photorealistic rendering has certainly been achieved at the expense of tremendous computational resources and corresponding rendering times; real-time rendering typically must accept a great number of compromises to achieve adequate performance, such as aliasing artifacts, the...

  • Analysis of Surface Heat Flux Anomalies to Understand Recent Northeast Pacific Marine Heatwave Events

    Creator:
    Yi-Wei, Chen
    Abstract:
    Several large-scale marine heatwave events occurred during the last 10 years in the North Pacific. A particular extreme marine heatwave in the North Pacific called the blob created an unprecedented high peak of sea surface temperature (SST) during 2013/14. MHW events had significant impacts on downstream weather and precipitation patterns...

  • The Occurrence of Coastal Sea Ice Leads and their Impact on the Beaufort Gyre

    Creator:
    Lewis, Benjamin J.
    Abstract:
    Leads are long fractures wide enough for a ship to travel through the ice pack. Sea ice acts as a barrier between the ocean and the atmosphere, whereas leads allow the transfer of heat and moisture between the two. Leads play a role for marine mammals and are hunting grounds...

  • Evolution of Turbulence, Heat Content, and Freshwater Lenses in the Diurnal Warm Layer

    Creator:
    Moulin, Aurélie J.
    Abstract:
    Thorough understanding of the mechanisms controlling the temperature structure in the surface mixed layer of the ocean and, in particular, accurate values of sea surface temperature are critical for properly parameterizing air-sea heat exchange and quantifying the amount of heat redistributed below the surface. It is however difficult to obtain...

  • Effects of solar heating on the indirect effect of aerosols as deduced from observations of ship tracks

    Creator:
    Christensen, Matthew W.
    Abstract:
    One kilometer Moderate Resolution Imaging Spectroradiometer (MODIS) observations for Terra (morning) and Aqua (afternoon) satellites were used to follow the morning to afternoon evolution of marine stratocumulus clouds that were affected by ship stack exhaust. The observations covered the summer months of 2002-2003 and August 2007 for marine layers off...

  • Vertical Structure of the Lower Troposphere in a Changing Arctic

    Creator:
    Watkins, Daniel M.
    Abstract:
    The Arctic climate system is changing dramatically as a response to rising atmospheric greenhouse gas concentrations. Key indicators of Arctic change include thinning and retreating of Arctic pack ice, thawing permafrost, greening tundra, and rising surface temperatures. The structure of the atmospheric boundary layer influences and is influenced by processes...

  • Response of marine stratus to successive polluting events by ships

    Creator:
    Sechrist, B.
    Abstract:
    Ship tracks have proven to be an ideal laboratory for studying the response of marine stratocumulus to an increase in aerosol pollution. Here the response of already polluted marine stratocumulus to further pollution was examined by studying the clouds where two ship tracks cross. 78 crossings of ship tracks were...

  • Relationship between tropical Atlantic Sea surface temperature variability and southern Indian Ocean tropical cyclones

    Creator:
    DeBlander, Evan F.
    Abstract:
    Recent studies have found that equatorial Atlantic sea surface temperature (SST) variability may be influencing tropical Indian Ocean climate (Kucharski 2009, Wang 2009). Due to the economic and social impact of tropical cyclones, it is important to investigate how an Atlantic-Indian Ocean connection may be affecting tropical cyclone behavior in...
