  • Buoy and satellite observation of wind induced surface heat exchange in the intraseasonal oscillation over West Pacific and Indian Ocean

    Creator:
    Araligidad, Nilesh
    Abstract:
    The importance of wind-driven latent heat fluxes for supporting tropical intraseasonal precipitation variability is analyzed. Tropical intraseasonal variability in the west pacific and Indian ocean is analyzed for northern and southern hemisphere summer during 1999-2005 using satellite and buoy observations. A composite analysis of QuikSCAT ocean vector winds and TRMM...

  • 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...

  • 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...

  • Evaluation of the predictive capability of two-phase flow maps for microchannel condensation of R-134a at low mass flux conditions

    Creator:
    VanderPutten, Michael A.
    Abstract:
    Predicting condensation flow regimes and the associated heat transfer and pressure drop in microchannels is critical for designing terrestrial and space systems for heating, cooling, power generation, and advanced manufacturing. It is well established that in flows approaching the microscale (Dh < 1 mm) gravity-dominated flow regimes become less relevant,...

  • Characterization of flow boiling in a fractal–like branching microchannel network

    Creator:
    Edward, Lee M.
    Abstract:
    Based on experimental investigations the present study evaluates flow instability and void fraction in a fractal-like branching microchannel network with rectangular cross-section. The hydraulic diameter of the channels ranged from 308μm at the inlet to 143μm at the outlet. The flow network used is characterized by set branching ratios for...

  • 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...

  • Getting to local information : the role of different costs

    Creator:
    Rajaram, Vidya
    Abstract:
    Finding information can cost a significant amount of time, even when the information is already stored on the user’s local computer system. There is significant research aimed at reducing these time costs, but little research into exactly what these costs are or how they impact people’s use of tools and...

  • 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...

  • Diurnal and subdiurnal variability in the Mars Pathfinder Presidential meteorology sessions

    Creator:
    Bennett, Scott
    Abstract:
    The Mars Pathfinder (MPF) arrived on the Martian surface on 4 July 1997 to become only the third successful landed mission to Mars, recording surface meteorological data intermittently over a period of 83 Martian days ("sols"). The in situ observations made by the MPF meteorology (MET) experiment were recorded at...

  • Using provenance to aid document re-finding

    Creator:
    Lonsdale, Heather
    Abstract:
    In the field of Human-Computer Interaction, provenance refers to the complete history and genealogy of a document. Provenance can be useful in identifying related resources, such as different versions of the same document or resources used in the creation of a new document. Though methods of provenance collection and applications...
