Simultaneously assimilating multivariate data sets into the two-source evapotranspiration model by Bayesian approach: application to spring maize in an arid region of northwestern China
Simultaneously assimilating multivariate data sets two-source evapotranspiration model Bayesian approach spring maize in an arid region of northwestern China
2014/12/19
Based on direct measurements of half-hourly canopy evapotranspiration (ET; W m−2) using the eddy covariance (EC) system and daily soil evaporation (E; mm day−1) using microlysimeters over ...
Constraints from the CMB temperature and other common observational data-sets on variable dark energy density models
Cosmology Dark energy Thermodynamics
2011/10/13
The thermodynamic and dynamical properties of a variable dark energy model with density scaling as rho_x \propto (1+z)^m, z being the redshift, are discussed following the outline of Jetzer et al. Thi...
Beach Morphology and Sediment Budget Variability Based on High Quality Digital Elevation Models Derived from Field Data Sets
Moroccan Coast Beach Change Wave Forcing Digital Elevation Model 3-D Approach
2013/3/6
The morphological and volumetric changes of a sandy beach were investigated through a series of two- monthly filed surveys carried out aver a 2-year period from April 2005 to January 2007. This paper ...
Late-time Kerr tails: generic and non-generic initial data sets,
generic non-generic superposition
2010/3/17
Three interrelated questions concerning Kerr spacetime late-time tails are considered, specifically the evolutions of generic and non-generic initial data sets, the excitation of "up" modes, and the r...
Distinguished hyperbolic trajectories in time-dependent fluid flows:analytical and computational approach for velocity fields defined as data sets
Distinguished hyperbolic trajectories time-dependent fluid flows velocity fields
2009/11/12
In this paper we develop analytical and numerical methods for finding special hyperbolic trajectories that govern geometry of Lagrangian structures in time-dependent vector fields. The vector fields (...
Spatio-temporal filling of missing points in geophysical data sets
Spatio-temporal filling missing points geophysical data sets
2009/11/9
The majority of data sets in the geosciences are obtained from observations and measurements of natural systems, rather than in the laboratory. These data sets are often full of gaps, due to to the co...
Stratospheric age of air computed with trajectories based on various 3D-Var and 4D-Var data sets
Stratospheric age trajectories 3D-Var 4D-Var
2009/1/23
The age of stratospheric air is computed with a trajectory model, using ECMWF ERA-40 3D-Var and operational 4D-Var winds. Analysis as well as forecast data are used. In the latter case successive fore...
Emissions of primary aerosol and precursor gases in the years 2000 and 1750 prescribed data-sets for AeroCom
primary aerosol precursor gases prescribed data-sets AeroCom
2009/1/15
Inventories for global aerosol and aerosol precursor emissions have been collected (based on published inventories and published simulations), assessed and prepared for the year 2000 (present-day cond...

Global modelling of continental water storage changes – sensitivity to different climate data sets
Global modelling continental water storage changes different climate data sets
2010/1/27
Since 2002, the GRACE satellite mission provides estimates of the Earth's dynamic gravity field with unprecedented accuracy. Differences between monthly gravity fields contain a clear hydrological sig...
Dynamic structure and data sets of a GIS database for geological riskanalysis in the Azores volcanic islands
Dynamic structure data sets GIS database geological riskanalysis Azores volcanic islands
2009/12/17
Geological hazards in the Azores archipelago include earthquakes, volcanic eruptions, degassing phenomena and landslides, being the cause of thousands of deaths and severe damage and loss. To reduce t...
Imbalanced data sets containing much more background than signal instances are very common
in particle physics, and will also be characteristic for the upcoming analyses of LHC data. Following up the...
