    Abstract
  • Using the GPS radio occultation data from June 2014 to May 2015 provided by FY-3C polar-orbiting satellites,the SNR disturbances of C/A code with sampling frequency of 50 Hz on a global scale are statistically analyzed,and the disturbance strength of sporadic E layers is also studied.Results show that the disturbance strength of sporadic E layer at mid-latitudes in the summer hemisphere area is far greater than that at the same latitudes in the winter hemisphere,and the disturbances of the sporadic E layers (Es) near the latitude of 40° are significantly enhanced.In addition,at 100 km height,the disturbances of Es layers reach the peaks at 10:00 LT and 22:00 LT. The occurrence rates of sporadic E in summer hemisphere are significantly higher than that in the winter hemisphere.The results observed by FY-3C satellite are consistent with those observed by the COSMIC system.Therefore,the occultation data of FY-3C satellite could be used to study ionospheric sporadic E layers.
