The FORMOSAT3/COSMIC RO retrieved ionospheric model is assessed for its bias by comparing with the OSSE simulated RO retrieved ionosphere using a theoretical ionosphere model derived from TIE-GCM.First,variances between the TIE-GCM model and an assimilated model derived combining the TIE-GCM Model with the FORMOSAT3/COSMIC RO retrieved data are obtained.The FORMOSAT 3/COSMIC RO retrieved data bias is defined as the calculated variance plus the differences between the OSSE RO retrieved data from the assimilated TIE-GCM model and the model itself.Using the FORMOSAT 3/COSMIC data on day 80 of 2007 as an example of illustration are compared with the ionosonde observation.We found the bias is most prominent at the bottomside below 200 km.

电离层不规则结构是电离层研究中的一个重要方面,扩展F 是电离层小尺度不规则结构在电离层F 层的重要表现,在采用高频多普勒手段进行电离层探测中,电离层F 层小尺度不规则结构引起回波描迹的扩散.在中、低纬区域,高频多普勒记录到的弥散回波(扩展F)情况绝大部分出现在日落后,发生在白天的回波弥散也不常见,相对的研究较少.本文在大量连续多普勒观测资料的基础上统计研究了出现在中纬地区白天的电离层不规则结构的表
