关键词α ‐ Chapman function COSMIC equatorial ionization anomaly empirical model of Ne profile mid‐ latitude trough topside ionosphere
DOI10.1029/2020SW002642
英文摘要The topside ionosphere accounts for a dominant part of the ionospheric total electron content, whereas accurate global modeling of topside ionospheric electron density (Ne) profile has not been fully achieved. In this study, a high precision Ne profile model, named alpha-Chapman Based Electron Density Profile Model (alpha-Chapman-Based-EDP), was built by using similar to 4.5 million Ne profiles from the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC-1) radio occultations. We first describe each of the profiles using five parameters of the alpha-Chapman function, that is, peak density (NmF2) and height (hmF2) of F2 layer, scale height (Hm) as well as its altitude change rates, and then built a model for each of the parameters as a function of latitude, longitude, month, local time, and solar activity, through Empirical orthogonal function (EOF) analysis and Fourier expansion. Combining all the five models, we construct the alpha-Chapman-Based-EDP. Compared with observations from COSMIC-1 and -2, the model captures the ionospheric climatology well, such as solar activity dependence, seasonal variation, and spatial pattern, including the equatorial ionization anomaly and midlatitude trough as well as their variabilities. Our model can describe nearly 80% variability of Ne in F region. In contrast, the IRI2016 cannot well reproduce these characteristics, with errors higher than our model. The potential applications of our model were also discussed. A dense matrix data calculated by the model will be released in with the permissions of COSMIC organizations.
