Introduction: The objective of our research project is to develop data mining and knowledge discovery in databases (KDD) techniques, using the “Data to Knowledge” (D2K) platform developed by National Center for Supercomputing Application (NCSA), to facilitate analysis, visualization and modeling of land-surface variables obtained from the TERRA and AQUA platforms in support of climate and weath...

On 10(3)- to 10(6)-year timescales, global sea level is determined largely by the volume of ice stored on land, which in turn largely reflects the thermal state of the Earth system. Here we use observations from five well-studied time slices covering the last 40 My to identify a well-defined and clearly sigmoidal relationship between atmospheric CO(2) and sea level on geological (near-equilibri...

Earth observation has been widely recognised as having considerable potential to aid an improved understanding of tropical forest biodiversity. However, studies that have explored the use of the multispectral response recorded by Earth observation satellites to infer climatically and edaphically determined floristically distinct tropical forest types have on the whole reported disappointing res...

[1] We compare, on a global scale, the degree of correlation between orientation of stream networks and topographic aspect on Mars and Earth. The orientation of streams on Earth is a reflection of local, underlying geology but, in general, it correlates with regional topographic aspect. However, the orientation of valley networks, prominent features on Mars, thought to be fossils of ancient str...

The lunar crust provides a record of the planetary formation and early evolutionary processes and contains a wealth of information about the origin and evolution of the Earth-Moon system (e.g., Taylor 1982; NRC 2007; Canup 2008, 2012; Cuk and Stewart 2012; Young et al. 2016). Understanding these processes is crucial for the reconstruction of the early evolutionary stages of the Earth, e.g., the...

We have examined the precision of interferometric SAR measurements of surface deformation of the Earth using 24-cm wavelength data acquired by the Japanese Earth Resources Satellite 1 (JERS 1) spacecraft, over the lzu peninsula, Japan. Radar images acquired from 1993 to 1994 were made into eleven independent interferograms. Apparent water vapor signatures with equivalent path delay up to 16 cm ...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract The snow accumulation and melt processes are well known to play an important role on the river flow regime, in particular this is enhanced for basin with complex topography where the snow dynamic is strongly affected by hillslope expositio...

(2015) An urgent case for higher resolution digital elevation models in the world's poorest and most vulnerable countries. Front. Earth Sci. 3:50. Natural disasters disproportionately impact the poorest countries; low-income developing countries accounted for 95% of all disaster fatalities between 1970 and 2008 (Handmer et al., 2012). These impacts are generally expected to worsen as the climat...
