Time series data in geophysics/space physics

1995 International Conference on Acoustics, Speech, and Signal Processing, 2002
Most geophysical and space physics data have time as one of the key variables in the data acquisition and subsequent analysis. Generally, in order to achieve physical understanding of these data, it is necessary to carry out comprehensive time series analyses.

Physics and geophysics

Physics Bulletin, 1986
I agree with Bruce Hobbs (Physics Bulletin October 1985 p421) that a discussion meeting between the Joint Association for Geophysics and a specialist group within The Institute of Physics would be of value. It would undoubtedly assist physicists' investigations into certain geophysical problems related to, for example, solid state, solar–terrestrial ...

Rock Physics and Integrated Geophysical Methods

78th EAGE Conference and Exhibition 2016, 2016
Rock physics represents the background for integrating multidisciplinary geophysical data. In fact, some type of physical relationship is necessary for linking the different data and parameters in the seismic, gravity and electromagnetic domains. In this work, I discuss the different types of relationships and how these can be included in the objective

Ultraviolet radiation physics in astronomy and geophysics

Journal of Quantitative Spectroscopy and Radiative Transfer, 1962
Abstract The astrophysicist has been compelled, in his studies of the solar and stellar atmospheres, to abandon in some cases the simpler “local thermodynamic equilibrium” approach. The new approach assumes statistical equilibrium and writes equations which concern the transfer of energy.

The Role of Experimental Physical Acoustics in Geophysics

Tectonophysics, 1972
Abstract In the last five years, the progress made by measurements on rocks and minerals, using physical acoustics, has been impressive. This, coupled with corresponding theoretical progress, has resulted in a number of refinements in the understanding of the structure and history of the earth's upper mantle.

Physical properties measurements for mineral exploration geophysics

SEG Technical Program Expanded Abstracts 2010, 2010
Despite the fact that hundreds of millions of dollars are spent annually on mineral exploration geophysics, the key physical parameters of the rocks and minerals involved are rarely systematically measured. Data that are publically available are often limited in scope, quality and supporting metadata.

Introduction of Special Physics Topics (Geophysics) through the Use of Physics Laboratory Projects

American Journal of Physics, 1970
A method is presented in which topics of a direct technological application are studied by students in technology taking a general physics course. It is found that student motivation is enhanced, and their interest in the over-all course increased, by such a presentation.

Ring-laser tests of fundamental physics and geophysics

Reports on Progress in Physics, 1997
HeNe ring-laser gyros are standard sensors in inertial guidance; mirror reflectances now reach 99.9999%. Present research instruments have an area of , a passive quality factor of , and a resolution of the frequency difference of counter-rotating optical beams approaching microhertz.

Simulations in Geophysics and Space Physics: Minisymposium Abstract

2007
High Performance Computing (HPC) enables increasingly complex computer models of physical processes to be built. Parallel computing, adaptive grids, and other computing tools are used to solve ever larger problems, but they also increase the complexity of the software significantly and can have an impact on the reliability of the software and the ...
