Abstract
This paper presents a study of ionospheric height fluctuation in the F-layer, which has the most irregularity of electron density in the ionosphere, in Thailand by using the ionosonde. The measurement location is at Chumphon campus of King Mongkut's Institute of Technology Ladkrabang: longitude 99.3 °E and latitude 10.7 °N. Obtained ionograms are then analyzed to determine equatorial spread-F and related parameters such as height (h'F) and critical frequency (foF2). The data are collected during the first 6 month of 2005. The results show that Spread F only occurs at night time and has the highest frequency in February and March, similar to the occurrence of amplitude scintillation in the ionosphere.
