Geomagnetic field is an essential parameter in Earth’s study. It also has broad applications in our daily life, such as natural resources exploration, navigation and so on. LEO space magnetometry is becoming a dominate way in modern magnetic field measurement, such as Swarm, CSES mission. CSES High Precision Magnetometer (HPM) includes two fluxgate magnetometers (FGM) and one Coupled Dark State Magnetometer (CDSM), which can provide magnetic field vector and intensity measurement from DC~15Hz. Now, the HPM payload is in good health and is operated continuously to provide data for scientific communities.
In this space science bazaar, I will first give an introduction of CSES HPM, including the data calibration and validation, flags for potential magnetic field disturbances from the satellite and its payload. Finally, some possible scientific applications of the data on global geomagnetic field modelling, lithosphere observations, Dst index estimation and ionosphere current studies such as FACs and EEJ (CEJ) are outlined.
