Calculation of Constitutive Parameters from Electric and Magnetic Field Measurements in an Anisotropic Medium with a Triaxial Instrument
Electrical Anisotropy Triaxial Measurement Electric and Magnetic Dipoles
2013/3/11
A hypothetical electric and magnetic induction tensor is considered in an anisotropic medium. The sources are magnetic dipoles. In such a medium, constitute parameters can be calculated by combining e...
Sample drying to improve HCHO measurements by PTR-MS instruments: laboratory and field measurements
HCHO PTR-MS laboratory and field measurements
2010/2/21
A significant improvement in the PTR-MS instrument sensitivity to formaldehyde was obtained by drying the air sample to a dew point of −30 °C using a cold trap to condense and freeze water vapou...
Field Measurements of the Total and Spectral Albedo of Snow and Ice in Dronning Maud Land, Antarctica
albedo spectral albedo snow blue-ice Antarctica
2009/6/9
Variabilities in the spectral and total (between 300-3000 nm) albedo of snow were studied in the Dronning Maud Land region of Antarctica during the austral summers of 1999/2000 and 2000/2001. The meas...
Comparison between field measurements and numerical simulation of steady-state solute transport in a heterogeneous soil profile
field measurements solute transport numerical simulation soil profile
2009/6/8
Field-scale solute dispersion is determined by water flow heterogeneity which results from spatial variability of soil hydraulic properties and soil moisture state. Measured variabilities of soil hyd...
