Paper Title
MODELLING THE DIURNAL ELECTRON DENSITY VARIATION OVER THE EQUATORIAL REGION
Authors
  NABILA SA'AT,  KARTHIGESU NAGARAJOO

Abstract
The ionosphere is a region at the atmosphere that contains high concentration of free electrons which is termed as electron density (Ne). In this work, the Ne was modelled for latitude from 0 to 50° and longitude from 100 to 120°, and the Ne was obtained from International Reference Ionosphere (IRI). IRI is the international standard for the climatologically specification of ionospheric parameters. Altitude of 350km was chosen to do this modelling as this has been presumed as the altitude where the content of the Ne is maximum over the equatorial region. The Ne was taken at four different local times (LT). They are 8.00am, 1.30pm, 6.30pm and 11.30pm from 1st June 2009 to 7th June 2009. This Ne values were modelled in 2 dimensions (latitude and longitude) using Table Curve 3D (TC3D). TC3D is software that can generate a mathematical equation for given latitude, longitude and Ne. Then, the Ne from IRI will be compared with TC3D and from MATLAB. However, due the variation in the solar activity, it is very hard to obtain the same mathematical model for the ionospheric formation at different time of a day and on different days.

Keywords- IRI, Ne, latitude, longitude, ionosphere modelling, diurnal variation
