摘要: International Reference Ionosphere extended to the plasmasphere (IRI-Plas) is upgraded analytically for assimilative mode of operation using GPS-derived Total Electron Content (TEC) reconstruction instantaneous ionospheric critical frequency and topside scale height at magnetic conjugate hemisphere. The performance IRI-Plas code examined with TECgps retrieved from Global Ionospheric Maps compared F2-layer eight ionosonde locations in East Asia region on both hemispheres during space weather storms solar maximum (2000) minimum (2006). Missing data are completed by cloning frequency. Decomposition electron density profile reveals opposite relative changes depending activity. W index computed desired consistent results obtained indicating departure values parameters their respective median varying quiet state intense storm.
