A Swarm lithospheric magnetic field model to SH degree 80 [PDF]
Earth, Planets and Space, 2016 The Swarm constellation of satellites was launched in November 2013 and since then has delivered high-quality scalar and vector magnetic field measurements. A consortium of several research institutions was selected by the European Space Agency to provide a number of scientific products to be made available to the scientific community on a regular ...

IOP Conference Series: Earth and Environmental Science, 2021 Abstract The earth’s lithospheric magnetic field is part of the main earth’s magnetic field. The lithospheric field has a very small value compared to the Earth’s main magnetic field, approximately less than 1%, and this field is generated at the earth’s crust and upper mantle.

A spherical harmonic model of the lithospheric magnetic field of Mars [PDF]
Journal of Geophysical Research: Planets, 2014 AbstractWe present a model of the lithospheric magnetic field of Mars which is based on Mars Global Surveyor orbiting satellite data and represented by an expansion of spherical harmonic (SH) functions up to degree and order 110. Several techniques were applied in order to obtain a reliable and well‐resolved model of the Martian lithospheric magnetic ...

Global lithospheric magnetic field modelling by successive regional analysis [PDF]
Earth, Planets and Space, 2006 AbstractPresent lithospheric field models, like the MF4 and CM4, are produced by least squares estimation using spherical harmonic basis functions with global support. Accounting for the different properties of magnetic data at low and high latitudes, a method that can take regional differences into account is proposed.

Modelling Earth's lithospheric magnetic field using satellites in low-perigee elliptical orbits
Geophysical Journal International, 2022 The sensitivity of magnetic measurements taken by satellites in elliptical orbits to the lithospheric magnetic field is studied by comparing the formal error variances of the lithospheric Gauss coefficients for various satellite orbital constellations.We compare the results obtained using a satellite in a near-polar circular orbit at 350 km altitude ...

Spatiospectral concentration of vector fields on a sphere [PDF]
, 2013 We construct spherical vector bases that are bandlimited and spatially concentrated, or, alternatively, spacelimited and spectrally concentrated, suitable for the analysis and representation of real-valued vector fields on the surface of the unit sphere,
