Assessing intra-seasonal land surface change and long term trends in the succulent Karoo biome using coarse resolution satellite and interpolated rainfall surfaces
The Succulent Karoo is a biodiversity hot spot situated along the west coast of southern Africa. While it is predominantly recognized as a west coast vegetation type its borders stretch as far east as Steytlerville in the Little Karoo. The area contains the largest number of endemic succulent …

Multiscale Dynamic Time and Space Warping
… complexity, it is only suitable for short and coarse resolution videos. In this thesis, we introduce Multiscale DTSW: a modification of DTSW that has linear time and space complexity (O(N)) with good accuracy. The first step in Multiscale DTSW is to apply the DTSW algorithm to coarse resolution …

Use of global datasets for downscaling soil moisture with the EMT+VS model
… remote sensing and land-surface models provide coarse-resolution (9-40 km) soil moisture estimates, but various applications require fine-resolution (10-30 m) soil moisture patterns. The Equilibrium Moisture from Topography, Vegetation, and Soil (EMT+VS) model downscales soil moisture using …

THE OBSERVED VARIATION OF COHERENT UPDRAFT OBJECTS WITH HEIGHT IN THE CONVECTIVE BOUNDARY LAYER
… and plumes rise to their condensation level. In coarse resolution climate and weather models these plume fluxes can be represented using "eddy-diffusivity mass-flux" (EDMF) parameterizations, wherein the "mass flux" is accomplished by a spectrum of buoyant plumes. In this presentation, we analyze …

Characterizing Surface Water from Space with Microwave Remote Sensing: Advancing Conventional and Emerging Approaches
… independent approaches: (1) a combination of coarse-resolution active and passive sensors, (2) synthetic aperture radar (SAR), and (3) bistatic Global Navigation Satellite System reflectometry (GNSS-R). Advancements in each method are presented along with discussion on the associated …

Modeling Mesoscale Eddies: the Effects of Resolution onOcean Turbulence
… a grid refinement study to determine the minimal resolution required to represent mesoscale eddies in the primitive equations. Convergence is evaluated through several metrics, including surface and depth-integrated kinetic energy, spectra, and zonally-averaged temperature, in order to establish …

Annual and Interannual Variability in the Wind Field and the Hydrography Along the Seward Line in the Northern Gulf of Alaska
… of winds on the system has been calculated using coarse resolution upwelling index data or spatially sparse buoy data. The coarse resolution wind measurements cannot describe the cross shelf spatial variations of the winds which are expected to be significant due to the influence of the high …

A NEW SUBAPERTURE APPROACH TO HIGH SQUINT SYNTHETIC APERTURE RADAR PROCESSING
… chirp rate in the azimuth direction followed by coarse-resolution Fast Fourier Transform (CRFFT) to produce the coarse-resolution image. Phase compensations are then performed onto the CRFFT outputs to remove the undesirable phase terms arise from deramping of the input signal. The final step of …

On the warm bias along the South-West African Coast in coupled models : an oceanic perspective
… the conclusion is reached that the insufficient resolution of the ocean component in the coupled model is responsible for the warm biases over the SWA coastal region. The coarse resolution used in the ocean model has an artificially stretched coastal side-wall boundary layer, which induces a …
