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 ...

Modelling Earth's lithospheric magnetic field using satellites in low-perigee elliptical orbits [PDF]
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 ...

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 ...

Fifth‐generation lithospheric magnetic field model from CHAMP satellite measurements [PDF]
Geochemistry, Geophysics, Geosystems, 2007 Six years of low‐orbit CHAMP satellite magnetic measurements have provided an exceptionally high‐quality data resource for lithospheric magnetic field modeling and interpretation. Here we describe the fifth‐generation satellite‐only magnetic field model MF5. The model extends to spherical harmonic degree 100.

Use of along-track magnetic field differences in lithospheric field modelling [PDF]
Geophysical Journal International, 2014 We demonstrate that first differences of polar orbiting satellite magnetic data in the along-track direction can be used to obtain high resolution models of the lithospheric field. Along-track differences approximate the north–south magnetic field gradients for non-polar latitudes.

A 2D Lithospheric Magnetic Anomaly Field over Egypt Using Gradient Data of Swarm Mission
Universe, 2022 The current work makes use of the geometrical configuration of the two lower-altitude Swarm satellites (Swarm A and C), moving side by side with a longitudinal distance of 1.4°, to estimate a two-dimensional (2D) model of the lithospheric magnetic ...

Evaluation of the lithospheric magnetic field mapped by the first year of MSS-1 data
Earth and Planetary PhysicsThe MSS-1 satellite began mapping Earth’s magnetic field in November 2023. Here, we perform a preliminary assessment of the new information provided on Earth’s lithospheric magnetic field from the first 12 months of data from MSS-1.

Geochemistry, Geophysics, Geosystems, 2008 The CHAMP satellite continues to provide highly accurate magnetic field measurements from decreasing orbital altitudes (<350 km) at solar minimum conditions. Using the latest 4 years (2004–2007) of readings from the CHAMP fluxgate magnetometer, including an improved scalar data product, we have estimated the lithospheric magnetic field to spherical ...
