Magma chambers: what we can, and cannot, learn from volcano geodesy

Philosophical Transactions of the Royal Society A, 2019
Geodetic observations on volcanoes can reveal important aspects of crustal magma chambers. The rate of decay of deformation with distance reflects the centroid depth of the chamber.

Improving InSAR geodesy using global atmospheric models [PDF]

, 2014
Spatial and temporal variations of pressure, temperature and water vapor content in the atmosphere introduce significant confounding delays in Interferometric Synthetic Aperture Radar (InSAR) observations of ground deformation and bias estimatesof ...

Comparison of Different Measurement Techniques as Methodology for Surveying and Monitoring Stainless Steel Chimneys

Geosciences, 2019
The measurement of a chimney axis is an engineering geodesy task. These measurements allow to assess the technical condition of chimneys and are usually carried out for reinforced concrete chimneys.

An influence of the covariance between single orbit parameters on the accuracy of observations of the pseudo-ranges and phase differences

Metrology and Measurement Systems, 2020
The possibilities to improve values of the satellite orbit elements by employing the pseudo-ranges and differences of carrier phase frequencies measured at many reference GPS stations are analysed. An improvement of orbit ephemeris is achieved by solving

Numerical simulations of the nonlinear Molodensky problem [PDF]

, 2013
We present a boundary element method to compute numerical approximations to the non-linear Molodensky problem, which reconstructs the surface of the earth from the gravitational potential and the gravity vector.

Advances in Stimuli‐Responsive Organic Materials and Polymers toward Intelligent CO2 Capture

Advanced Functional Materials, EarlyView.
Schematic illustration of the relationship between different stimuli and stimuli‐responsive organic materials and polymers for carbon dioxide (CO2) capture. Main stimuli include redox, pH, magnetism, temperature, light, and pressure. Furthermore, multi‐responsive materials, due to their high adaptability and scalability in complex environments, are ...
