来自东南亚赤道电离层探测网络（SEALION）的结果表明了F3层的有趣性质，显示了其生成机制。2004年11月16日和2005年3月31日在清迈获得的电离图（CMU;地理纬度18.8°N，地理经度98.9°E，磁纬度13.2°N），春蓬（CPN; 10.7°N，99.4°E，and 3.2°N）和Kototabang（KTB; 0.2°S，100.3°E，and 10.1°S）显示了磁赤道附近的CPN与磁低纬地区的CMU和KTB之间的显著差异。利用SEALION电离层探测仪网络数据对F3层进行的同步磁共轭观测表明，F3层明显依赖于磁纬度。我们认为，F3层的这些磁纬度依赖性可以通过考虑等离子体扩散效应沿着在磁性低纬度地区的磁力线来解释。
Results from the meridional ionosonde network located in Southeast Asia (SEALION) demonstrate the interesting nature of the F3 layer, showing its generation mechanism. Ionograms obtained on 16 November 2004 and 31 March 2005 at Chiang Mai (CMU; geographic latitude 18.8°N, geographic longitude 98.9°E, and magnetic latitude 13.2°N), Chumphon (CPN; 10.7°N, 99.4°E, and 3.2°N) and Kototabang (KTB; 0.2°S, 100.3°E, and 10.1°S) showed significant differences between CPN near the magnetic equator, and CMU and KTB in the magnetic low‐latitude region. The simultaneous magnetic conjugate observations of the F3 layer achieved using the SEALION ionosonde network data showed clear dependences of the F3 layer on the magnetic latitude. It is suggested that these magnetic latitude dependences of the F3 layer can be explained by considering the plasma diffusion effects along the magnetic field lines in the magnetic low‐latitude region.
