英文摘要In the inversion of ionospheric occultation data, Abel method is usually applied, which is based on the approximation that the electron density distribution is spherical symmetry in the local ionosphere. This approximation will lead to errors because of the spherical asymmetry of the real ionosphere. This paper studies a new method, which uses the gradient information of three dimensional ionosphere model to constrain the inversion, called three dimensional model constrained inversion method for ionospheric occultation data (3-D constrained method). Then the method is applied in the inversion of simulated data and real observation data respectively. The inversion of simulated data shows that 3-D constrained method reduces the inversion errors greatly. Then the real ionospheric occultation data is retrieved with the IRI2001 model as constraint, and the inversion results are compared with the ionosonde measurements. The results show that 3-D constrained method and Abel method can both retrieve the ionospheric occultation data well.
