NEDM2020

The Neustrelitz Electron Density Model (NEDM2020) is a three-dimensional electron density model developed at German Aerospace Center (DLR) for supporting space weather services and mitigation of propagation errors for trans-ionospheric signals. The 3D electron density distribution is modelled by combining a Chapman layer representing the ionospheric F-layer, an E-layer model and a plasmasphere model. The topside ionosphere and plasmasphere is modelled by superposing the Neustrelitz Plasmasphere Model (NPSM) to the F-layer and E-layer models. The combined model describes the ionosphere and plasmasphere up to GNSS orbit height of about 20,000 km. Knowing the F10.7 in advance NEDM2020 can predict the electron concentration at any given location and time in the ionosphere for trans-ionospheric applications. Use of a limited number of model coefficients (< 100) and no interpolation for model parameters makes NEDM2020 a fast running model and suitable for operational purpose.
