The Martian crustal magnetic field: a global view as seen from MGS and MAVEN measurements

We present a new model of the Martian crustal magnetic field. This new model supersedes previously published models as it fully  exploits the full wealth of available magnetic field measurements. The new model makes advances in four areas. (i) We apply a data selection scheme for MGS MAG Mapping Orbit (M0) measurements in order to reduce external field perturbations. (ii) We make use  of MGS Electron Reflectometry (ER) indirect estimates of the total field to better constrain the model. (iii) We further consider MAVEN  magnetic field measurements, until the most recent date. (iv) We improve the spatial resolution, down to ~100 km.
