A new climatological electron density model for supporting space weather services

The ionosphere is the ionized part of Earth’s atmosphere, ranging from about 60 km up to several Earth radii, whereas upper above 1000 height plasmapause usually called plasmasphere. We present a new three-dimensional electron density model support space weather services and mitigate propagation errors for trans-ionospheric signals. developed by superposing Neustrelitz Plasmasphere Model (NPSM) an composed separate F E-layer distributions. It uses TEC (NTCM), Peak Density (NPDM), Height (NPHM) total content (TEC), peak ionization, information. These models describe spatial temporal variability key parameters as function local time, geographic/geomagnetic location, solar irradiation, activity. calculate concentration at any given location time in applications named Electron (NEDM2020). A comprehensive validation study conducted against in-situ data DMSP Swarm, Van Allen Probes ICON missions, topside COSMIC/FORMOSAT-3 mission, bottom side TOPEX/Poseidon ground-based International GNSS Service (IGS) covering both high low activity conditions. Additionally, performance compared with 3D NeQuick2. Our investigation shows that NEDM2020 performs better than NeQuick2 satellites COSMIC missions. When IGS data, perform very similarly.
