A Lagrangian advection scheme with shape matrix (LASM) for solving advection problems
solving advection problems Lagrangian advection scheme
2014/12/19
A new Lagrangian advection scheme with shape matrix (LASM) is proposed to take advantage of the extreme low numerical diffusion of the Lagrangian methods. The tracer is discretized into finite parcels...
Improving computational efficiency in large linear inverse problems: an example from carbon dioxide flux estimation
computational efficiency large linear inverse problems carbon dioxide flux estimation
2014/12/12
Addressing a variety of questions within Earth science disciplines entails the inference of the spatiotemporal distribution of parameters of interest based on observations of related quantities. Such ...
Calculation of Standard Thermodynamic Potentials for Na-Zeolites with the Use of Linear Programming Problems
Na-Zeolites Standard Thermodynamic Potentials Linear Programming
2013/3/7
Linear programming problems for Na-Al-Si-O-H system have been formulated and solved for calculations of standard enthalpies and Gibbs potentials of zeolites with unknown thermodynamic properties. The ...
Modern techniques and Old Red problems–determining the age of continental sedimentary deposits with 40Ar/39Ar provenance analysis in west-central Norway
Modern techniques Old Red problems continental sedimentary deposits 40Ar/39Ar provenance analysis
2009/12/3
Ages of continental 'Old Red Sandstone' (ORS) deposits in Norway have been notoriously difficult to obtain due to the paucity of fossil-bearing horizons. In general, 40Ar/39Ar ages from detrital mica ...
Hilbert problems for the geosciences in the 21st century
Hilbert problems for the geosciences 21st century
2009/11/12
The scientific problems posed by the Earth's fluid envelope, and its atmosphere, oceans, and the land surface that interacts with them are central to major socio-economic and political concerns as we ...
'Killer' Southeast Drought Low on Scale, Says Study--Others Were Far Worse; Population, Planning Are the Real Problems（图）
'Killer' Southeast Drought Population Planning the Real Problems
2009/12/10
A 2005-2007 dry spell in the southeastern United States destroyed billions of dollars of crops, drained municipal reservoirs and sparked legal wars among a half-dozen states—but the havoc came not fro...
A multi-institutional and interdisciplinary approach to the assessment of vulnerability and adaptation to climate change in the Peruvian Central Andes:problems and prospects
interdisciplinary approach vulnerability climate change Peruvian Central Andes
2010/1/27
A local integrated assessment of the vulnerability and adaptation to climate change in the Mantaro River Basin, located in Peruvian Central Andes, was developed between years 2003 to 2005. In this pap...
Using in-situ temperature measurements to estimate saturated soil thermal properties by solving a sequence of optimization problems
in-situ temperature measurements saturated soil thermal properties optimization problems
2010/2/4
We describe an approach to find an initial approximation to the thermal properties of soil horizons. This technique approximates thermal conductivity, porosity, unfrozen water content curves in horizo...
