Research has shown that impervious surfaces, a consequence of development, have a direct impact upon stream quality. Local planners and land-use officials need simple tools to help them determine the amount of impervious surface within watersheds and to assess impacts from future development. This paper describes an ArcView GISbased model being developed by the Northeast Regional Earth Science ...

Dust storms in North China result in high concentrations of airborne dust particles, which cause detrimental effects on human health as well as social and economic losses and environmental degradation. To investigate the impact of land surface processes on dust storms, we simulate two dust storm events in North China during spring 2002 using two versions of a dust storm prediction system develo...

The land surface is a key component of climate models. It controls the partitioning of available energy at the surface between sensible and latent heat, and it controls the partitioning of available water between evaporation and runoff. The land surface is also the location of the terrestrial carbon sink. Evidence is increasing that the influence of the land surface is significant on climate an...

Here we describe a technique to exploit the differential atmospheric paths sampled by ATSR-2 imagery to separate the contributions from atmospheric aerosol and land surface scattering, for the solar reflective channels. The result is an image of the land surface reflectance, relatively uncontaminated by atmospheric scattering, and a separate image of the atmospheric aerosol loading. A general m...

The authors use a sophisticated coupled land–atmosphere modeling system for a Southern Hemisphere subdomain centered over southeasternAustralia to evaluate differences in simulation skill from two different land surface initialization approaches. The first approach uses equilibrated land surface states obtained from offline simulations of the land surface model, and the second uses land surface...
