Fig. 8From: The CSES global geomagnetic field model (CGGM): an IGRF-type global geomagnetic field model based on data from the China Seismo-Electromagnetic SatelliteLatitude versus time distribution of the selected CSES data used for building the CGGM parent model (red: FGM_S1 vector data; blue: CDSM scalar data), note the gaps around 65°N and 65°S due to unavailability of CDSM data in this transition from Type 1 to Type 2 data available at the time of modellingBack to article page
