Defining the temporal and geographic limits for an urban mapping study Defining the temporal and geographic limits for an urban mapping study

Urban mapping research has demonstrated that historic maps can be integrated with remotely sensed data and related geographic information to successfully detect changing urban land characteristics for large metropolitan areas. Effective and efficient temporal mapping requires that procedures be defined for selecting the temporal range and geographic extent of a study area. Procedures...

Radar reflectivities of plausible Titan surfaces Radar reflectivities of plausible Titan surfaces

We consider plausible reflectivity ranges for candidate Titan surfaces, with application to radar altimeter investigations on both the Cassini Orbiter and Huygens Probe. The appropriate measure of surface scattering is the specific backscatter cross-section at normal incidence or, for smooth surfaces, the specific backscatter averaged over the sensitivity of the altimeter beam pattern. A...

Natural attenuation of chlorinated hydrocarbons in a freshwater wetland Natural attenuation of chlorinated hydrocarbons in a freshwater wetland

Natural attenuation of chlorinated volatile organic compounds (VOC's) occurs as ground water discharges from a sand aquifer to a freshwater wetland at Aberdeen Proving Ground, Md. Field and laboratory results indicate that biotransformation in the anaerobic wetland sediments is an important attenuation process. Relatively high concentrations of the parent compounds trichloroethylene (TCE...
