    Abstract
  •    Using spread F observations and GPS L1band ionospheric scintillation observations recorded by ionosonde and GPS L1band Ionospheric Scintillation monitor respectively in Haikou region during August 2012 and July 2013, we carried out correlation analysis on the occurrence time of each other. It’s found that there is a good correlation between the occurrences of Spread F and GPS L1band ionospheric scintillation. The correlation coefficient is 095.Due to development and evolution characteristics of lowlatitude ionospheric irregularities during solar maximum and different observing modes of equipments, the average starting time of GPS ionospheric scintillations is a little earlier than that of Spread F, and the average end time of the latter is somewhat lagged. Analysis from the statistical results also showed that small scale irregularities less than 1km died off firstly in the decay phase of ionospheric irregularities.
