“…Relatively high spatial resolution and good image geometric fidelity is required to resolve smaller alpine glaciers and glacier features. High spatial resolution also permits spatial analysis of glacier surfaces, such that ice flow and structural characteristics can be assessed and mapped (e.g., Bishop et al 1998). In addition, scene coverage should be large enough to enable regional analysis.…”

The international scientific community is actively engaged in assessing ice sheet and alpine glacier fluctuations at a variety of scales. The availability of stereoscopic, multitemporal, and multispectral satellite imagery from the optical wavelength regions of the electromagnetic spectrum has greatly increased our ability to assess glaciological conditions and map the cryosphere. There are, however, important issues and limitations associated with accurate satellite information extraction and mapping, as well as new opportunities for assessment and mapping that are all rooted in understanding the fundamentals of the radiation transfer cascade. We address the primary radiation transfer components, relate them to glacier dynamics and mapping, and summarize the analytical approaches that permit transformation of spectral variation into thematic and quantitative parameters. We also discuss the integration of satellite-derived information into numerical modeling approaches to facilitate understandings of glacier dynamics and causal mechanisms.

“…One of the greatest limiting factors in predicting and mapping landslide activity is the lack of understanding of scale-dependent processes, such as erosion, weathering, and fracturing. The literature on this topic is predominantly theoretical, although several uses of remote sensing and statistics to describe scale and morphometric parameters have been proposed (Bishop et al, 1998(Bishop et al, , 2003Bonk, 2002;Phillips, 2005;Wallace et al, 2004). Previous studies have linked landslide processes with morphology and slide components (Smith, 2001;Korup, 2004;McKean and Roering, 2004).…”

“…High-magnitude erosion and uplift governed by climate forcing is responsible for relief production and extreme topographic anisotropy that is also governed by lithological variations. Collectively, such complex topographic variation regulates precipitation rates, orographic precipitation gradients, shortwave and longwave irradiance fluxes, glacier debris-load depth, and highly variable glacier states and dynamics [27,33,66,106]. Consequently, precipitation forcing is responsible for positive glacier mass-balance conditions and advancing glaciers [30,59], although the issue of mass loading as a contributing factor to the surging mechanism is not known with certainty [107].…”

Abstract:Understanding climate-glacier dynamics in High Mountain Asia is of critical importance to address issues including water resources, sea-level rise, mountain geodynamics, natural hazards and ecosystem sustainability. The Karakoram Himalaya is arguably the least understood region, given its extreme topography, climate-system coupling, and advancing and surge-type glaciers that exhibit complex flow patterns. Glacier fluctuations in the Karakoram Himalaya are highly variable in space and time because of numerous controlling factors, including the westerlies, the Indian summer monsoon, various teleconnections, topographic effects, glacier debris-cover characteristics, glacier dynamics, and geological conditions. The influence of the integrative coupling of forcing factors, however, has not been adequately assessed for characterizing the glaciers in the Karakoram Himalaya. Given the scarcity of in-situ data and the difficulty of conducting fieldwork on these glaciers, recent research has focused on utilizing remote sensing, geospatial technologies, and scientific modeling to obtain baseline information about the state of glaciers in the region. This review summarizes our current knowledge of glaciers, climate-glacier interaction, and topographic forcing in the Karakoram Himalaya, and demonstrates the complexities in mountain geodynamics that influence climate-glacier dynamics. Innovative analysis is also presented in support of our review and discussion.
