Inter-Calibration and Statistical Validation of Topside Ionosphere Electron Density Observations Made by CSES-01 Mission

The China Seismo-Electromagnetic Satellite (CSES-01) provides in situ electron density (Ne) observations through Langmuir probes (LPs) the topside ionosphere since February 2018. CSES-01 is a sun-synchronous satellite probing around two fixed local times (LTs), 14 LT daytime sector and 02 night-time sector, at an altitude of about 500 km. Previous studies evidenced that seems to underestimate Ne measurements with respect those acquired by similar satellites or obtained from different instruments. To overcome this issue, we calibrated LP Swarm B data, which flies approximately altitude. As first step, were Faceplate (FP) same satellite. Such calibration allowed solving overestimation made during nighttime for low solar activity. Then, used calibrate on statistical basis. Finally, goodness proposed procedure was statistically assessed comparison incoherent scatter radars (ISRs) located Jicamarca, Arecibo, Millstone Hill. underestimation issue both sectors brought agreement corresponding ones measured B, ISRs, modelled International Reference Ionosphere (IRI). This fundamental step towards possible future inclusion dataset underlying IRI purpose improving description IRI.
