IRI model application in low latitude ionospheric tomography

摘要: Abstract We report the progress in developing a Low-latitude Ionospheric Tomography Network (LITN) along 121°E meridian(Figure 1). LITN consists of an array NNSS receiving stations covering latitude range from Manila to Shanghai, and is specifically designed enable large scale tomographic imaging over equatorial anomaly region. Recently, we successfully applied computerized technique obtain two-dimensional(2D) images ionospheric electron density using measured TEC data network. The reconstruction based on multiplicative algebraic IRI model as initial guess. To verify quality image, profiles are reproduced image compared with by ionosonde. It will be shown that models can used facilitate such reconstruction.
