  • A satellite-derived climatology of global ocean winds

    Creator:
    Risien, Craig Miller
    Abstract:
    A satellite-derived Climatology of Global Ocean Winds (COGOW) on a 0.5° latitude by 0.5° latitude grid is presented based on 5-years (August 1999 July 2004) of measurements from the SeaWinds scatterometer that was launched on 19 June 1999 onboard the QuikSCAT satellite. SeaWinds is an active microwave radar that estimates...

  • Estimation and modeling of selected forest metrics with lidar and Landsat

    Creator:
    Strunk, Jacob L.
    Abstract:
    Lidar is able to provide height and cover information which can be used to estimate selected forest attributes precisely. However, for users to evaluate whether the additional cost and complication associated with using Lidar merits adoption requires that the protocol to use lidar be thoroughly described and that a basis...

  • Sea surface height and geostrophic velocity variability in the California current system as observed from the TOPEX altimeter

    Creator:
    Righi, Dylan D.
    Abstract:
    Eight years (1994-2000) of data from the TOPEX/Poseidon satellite altimeter are used to investigate the variability of the sea surface height and geostrophic velocity of the California Current system. The TOPEX/Posiedon satellite measures SSH along an exact-repeat set of groundtracks with a 10-day repeat cycle. In the domain studied here...

  • Remote sensing of forest aboveground biomass using the Geoscience Laser Altimeter System

    Creator:
    Pflugmacher, Dirk
    Abstract:
    Accurate estimates of forest aboveground biomass are needed to reduce uncertainties in the terrestrial carbon flux. The Geoscience Laser Altimeter System (GLAS) onboard the Ice, Cloud and land Elevation Satellite is now the first spaceborne lidar sensor that will provide global estimates of vegetation height. This study investigated the utility...

  • Remote sensing of forest biomass dynamics using Landsat-derived disturbance and recovery history and lidar data

    Creator:
    Pflugmacher, Dirk
    Abstract:
    Improved monitoring of forest biomass is needed to quantify natural and anthropogenic effects on the terrestrial carbon cycle. Landsat's temporal and spatial coverage, fine spatial grain, and long history of earth observations provide a unique opportunity for measuring biophysical properties of vegetation across large areas and long time scales. However,...

  • Vertical structure and aboveground biomass of tropical forests from lidar remote sensing

    Creator:
    Gonçalves, Fabio Guimarães
    Abstract:
    Methods for obtaining accurate, spatially explicit estimates of biomass density in tropical forests are required to reduce uncertainties in the global carbon cycle, and to support international climate agreements and emerging carbon markets. Three-dimensional (3-D) remote sensing techniques sensitive to the vertical structure of vegetation provide a unique opportunity for...
