| Summary: | The ionosphere study is carried out in Malaysia for September 2004 using
ionosphere sounder. The main purpose of the study is to determine the parameters used to
search the variability of the ionospheric region in Malaysia. Observations and analysis
using gathered data from the colleting and storing data in the sounder system. The result
base on the ordinary wave critical frequency for stratification in the F region, foF2, the
virtual height for ordinary wave critical frequency or foF2, and the ordinary wave critical
frequency from the lowest thick layer of E region. The 24 hours data from 1 September to
30 September have been done to search the median, lower decile and upper decile
frequency. The changes of the frequency is dependent on the solar activity in the
morning. The highest critical frequency is 6.8 to 12 MHz and decreasing value due to late
evening and night time at 7 MHz. The virtual height for this frequency are 200 to 480
km. The E-region frequency is from 2.2 to 9.1 MHz. |
