Fig. 9.From: A comparison of a model using the FORMOSAT-3/COSMIC data with the IRI modelVertical scale height at 450 km derived by the F3/C model (top) and IRI model (bottom) at 1200 LT in March (a), June (b), September (c) and December (d). White curves indicate magnetic equator. Intensities of EUV applied in the calculations are the same as Fig. 6.Back to article page
