P. Potapov, Matthew C. Hansen, S.V. Stehman, Thomas R. Loveland, K. Pittman
2008, Remote Sensing of Environment (112) 3708-3719
Estimation of forest cover change is important for boreal forests, one of the most extensive forested biomes, due to its unique role in global timber stock, carbon sequestration and deposition, and high vulnerability to the effects of global climate change. We used time-series data from the MODerate Resolution Imaging Spectroradiometer...

S.K. Maxwell, M.E. Craig
2008, Geocarto International (23) 169-179
Failure of the Scan Line Corrector (SLC) on the Landsat ETM+ sensor has had a major impact on many applications that rely on continuous medium resolution imagery to meet their objectives. The United States Department of Agriculture (USDA) Cropland Data Layer (CDL) program uses Landsat imagery as the primary source...

2008, Geophysical Research Letters (35)
Recently available satellite land cover land use (LCLU) and albedo data are used to study the impact of LCLU change from 1973 to 2000 on surface albedo and radiative forcing for 36 ecoregions covering 43% of the conterminous United States (CONUS). Moderate Resolution Imaging Spectroradiometer (MODIS) snow-free broadband albedo values...
Landsat still contributing to environmental research
Thomas R. Loveland, Mark A. Cochrane, Geoffrey M. Henebry
2008, Trends in Ecology and Evolution (23) 182-183
Landsat data have enabled continuous global monitoring of both human-caused and other land cover disturbances since 1972. Recently degraded performance and intermittent service of the Landsat 7 and Landsat 5 sensors, respectively, have raised concerns about the condition of global Earth observation programs. However, Landsat imagery is still useful for...

2008, International Journal of Digital Earth (1) 196-220
High-latitude ecosystems are exposed to more pronounced warming effects than other parts of the globe. We develop a technique to monitor ecological changes in a way that distinguishes climate influences from disturbances. In this study, we account for climatic influences on Alaskan boreal forest performance with a data-driven model. We...

Detecting changes in riparian habitat conditions based on patterns of greenness change: A case study from the Upper San Pedro River Basin, USA
K. Bruce Jones, Curtis M. Edmonds, E. Terrence Slonecker, James Wickham, Anne Neale, Timothy G. Wade, Kurt H. Riitters, William Kepner
2008, Ecological Indicators (8) 89-99
Healthy riparian ecosystems in arid and semi-arid regions exhibit shifting patterns of vegetation in response to periodic flooding. Their conditions also depend upon the amount of grazing and other human uses. Taking advantage of these system properties, we developed and tested an approach that utilizes historical Landsat data to track changes in the patterns of greenness (Normalized Difference...

J.A. Mason, J. B. Swinehart, H. Lu, X. Miao, P. Cha, Y. Zhou
2008, Geomorphology (102) 351-363
The climatic controls on dune mobility, especially the relative importance of wind strength, remain incompletely understood. This is a key research problem in semi-arid northern China, both for interpreting past dune activity as evidence of paleoclimate and for predicting future environmental change. Potential eolian sand transport, which is approximately proportional...

S.W. Myint, M. Yuan, R.S. Cerveny, C. Giri
2008, Natural Hazards and Earth System Sciences (8) 707-719
Remote sensing of a natural disaster's damage offers an exciting backup and/or alternative to traditional means of on-site damage assessment. Although necessary for complete assessment of damage areas, ground-based damage surveys conducted in the aftermath of natural hazard passage can sometimes be potentially complicated due to on-site difficulties (e.g., interaction...
