  • Landsat thematic mapper data are used to estimate instantaneous regional-scale surface water and energy fluxes in a semi-arid Great Basin desert of the western United States. Results suggest that it is possible to scale from point measurements
  • of environmental state variables to regional estimates of water and energy exchange. This research characterizes the unifying thread in the classical climate-topography-soil-vegetation relation, the surface water and energy balance, through maps of the partitioning

  • This paper explores the commonly negative human reaction to environmental change. First, it assesses landscape change, defined specifically as the modification of land cover characteristics in the United States over the last couple of decades
