Abstract	The relative total electron content (TEC) is obtained through the combination of COSMIC radio occultation ionospheric measurements L1 and L2 phase. The TEC data are then calibrated by non-occultation observation data on the auxiliary side to remove portion of TEC above the LEO orbit altitude. The electron density profile can be retrieved from TEC by Abel integral transformation, with a spherically symmetric assumption of electron density and an approximation of signal straight-line propagation. The computation standard deviation of F(2)-layer critical frequency f(0)F(2) is about 0.59 MHz, and the standard deviation of F(2)-layer peak altitude h(m)F(2) is about 33.08 km, as through comparing 4903 COSMIC ionospheric occultation profiles with those from ionosonde stations, of which the longtitude deviations are less than 10 degrees, the latitude deviations are less than 2 degrees.
