Abstract
Chaos has found applications in many disciplines including radio communication. It has been applied to secure communication and time series analysis of many parameters. This study investigates chaos in the calculated refractive index over Akure using a two year data obtained from ongoing measurement of some atmospheric parameters by the communication and atmospheric physics research group, FUT, Akure. Chaos in the time series was investigated using phase space reconstruction, time delay, embedding dimension and Lyapunov exponent. Preliminary results shows positive Lyapunov exponent, hence, long term prediction of refractive index is impossible.
