AbstractAn empirical model of electron density (Ne) was constructed by using the data obtained with an impedance probe on board Japanese Hinotori satellite. The satellite was in circular orbit of the height of 600km with the inclination of 31 degrees from February 1981 to June 1982. The constructed model gives Ne at any local time with the time resolution of 90min and between −25 and 25 degrees in magnetic latitude with its resolution of 5 degrees in the range of F10.7 from 150 to 250 under the condition of Kp<4. Spline interpolations are applied to the functions of day of year, geomagnetic latitude and solar local time, and linear interpolation is applied to the function of F10.7. Longitude dependence of Ne is not taken into account. Our density model can reproduce solar local time variation of electron density at 600km altitude better than current International Reference Ionosphere (IRI2001) model which overestimates Ne in night time and underestimates Ne in day time. Our density model together with electron temperature model which has been constructed before will enable more understanding of upper ionospheric phenomenon in the equatorial region.
