Global morphology of ionospheric irregularities in the low latitudes using Radio occultation technique

  • 摘要: 基于气象、电离层和气候星座观测系统(constellation observing system for meteorology, ionosphere and climate, COSMIC)掩星闪烁指数观测数据,将遮掩点的位置作为电离层不均匀体出现的位置,对比分析了电离层E区不均匀体和F区不均匀体随时间、空间、太阳活动和地磁活动的变化. 发现E区闪烁主要出现于夏季半球的中纬地区;而F区闪烁主要出现于春秋季的磁赤道和低纬地区,受到地磁场的强烈控制. 除季节因素外,太阳活动对E区闪烁的影响并不是基本的,而赤道异常和赤道附近的F区闪烁受到太阳活动的显著控制:相比太阳活动低年,高年的F区闪烁强度更大,且扩展至更高的纬度. 地磁扰动时,中低纬地区电离层E区闪烁的全球分布与地磁平静时相似,但是闪烁的强度总体上略有增加,尤其是凌晨时段(00:00—06:00LT);中低纬地区电离层F区闪烁的全球分布也与地磁平静时相似,但是闪烁强度明显增加,且扩展至更高的纬度,尤其是00:00—06:00LT及18:00—24:00LT的太平洋扇区. 两者对比表明,电离层F区闪烁对地磁活动更为敏感. 将COSMIC掩星与天基原位观测的闪烁出现率结果进行对比,发现掩星手段不仅可以反映全球尺度的电离层不均匀体变化特征,包括它随季节/经度、地方时、太阳活动和地磁纬度的变化,而且可以反映电离层不均匀体随高度的变化,这是以往的观测手段难以拥有的.
