我们首次利用气象、电离层和气候星座观测系统(COSMIC‐2)对电子密度剖面的多卫星观测,报告了赤道电离层F2层(hmF2)高度纵向结构的逐日变化。这些观测结果揭示了在2021年1月30日至2月14日的固定本地时间框架内观察到的hmF2波数4结构的约3天调制。与此同时,通过电离层连接探测器(ICON)全球高分辨率热层成像迈克尔逊干涉仪(might)在~ 100公里的纬向风观测中识别出~ 3天的行星波活动。在~ 180-250 km高度没有观测到这一特征,这表明该波在F‐区域以下有耗散。我们提出,在hmF2中发现的3天的变化可能是由行星波-潮通过E区发电机相互作用引起的。
We report for the first time the day‐to‐day variation of the longitudinal structure in height of the F2 layer (hmF2) in the equatorial ionosphere using multi‐satellite observations of electron density profiles by the Constellation Observing System for Meteorology, Ionosphere and Climate‐2 (COSMIC‐2). These observations reveal a ∼3‐day modulation of the hmF2 wavenumber‐4 structure viewed in a fixed local time frame during January 30–February 14, 2021. Simultaneously, ∼3‐day planetary wave activity is discerned from zonal wind observations at ∼100 km by the Ionospheric Connection Explorer (ICON) Michelson Interferometer for Global High‐Resolution Thermospheric Imaging (MIGHTI). This signature is not observed at ∼180–250 km altitudes, suggesting the dissipation of this wave below the F‐region. We propose that the 3‐day variation identified in hmF2 is likely caused by the planetary wave‐tide interaction through the E‐region dynamo.
