Short summary
Using an empirical approach put forward by Makela et al. (2001), firstly, we propose a novel technique to calibrate OI 777.4 and 630.0 nm emission intensities using COSMIC/FORMOSAT-3 electron density profiles. Next, electron density maximum (Nm) and its height (hmF2) of the F layer are derived from the information of two calibrated intensities. Sample Nm and hmF2 maps are also generated to show the usefulness of this technique in studying ionospheric processes.
