Abstract
Fourier analysis is used to find the semi-annual variation of the thermospheric total density; the variation is characterized by a "Density index D". The results of the individual annual runs were subjected to statistical treatment and a formula for the semi-annual variation was found. It is then compared to the formula used in the CIRA 72 model.
