摘要以英国气象局的闪电探测网--到达时差网(ATDnet)为例,研究了虚拟电离层反射高度的时空变化。来自这个网络的数据,在13.7 kHz下运行,以及由气象局根据已发表的理论建立的传播模型被用来研究这种变化,特别是关于昼夜,季节和11年的太阳周期变化。选择这些时间尺度上的变化,因为它们对应于地球大气层上太阳辐照度的变化,这是已知的驱动电离层高度变化的因素。从2013年6月1日至8月31日(包括首尾两天),虚拟电离层反射高度在协调世界时1000-1600时期间为约65公里,在协调世界时2200-0400时期间为约80公里。季节性变化幅度也类似,2013年8月白天电离层高度约为64公里,2013年12月约为76公里。没有意义...
AbstractThe virtual ionosphere reflection height variation is investigated temporally and spatially, with specific reference to the Met Office’s lightning detection network, the Arrival Time Difference Network (ATDnet). Data from this network, operating at 13.7 kHz, and a propagation model built by the Met Office based upon published theory were used to investigate this variation, specifically with regard to diurnal, seasonal, and 11-yr solar cycle variation. Variation over these temporal scales is chosen, since they correspond with variation in solar irradiance upon the earth’s atmosphere, something known to drive ionosphere height variation. The virtual ionosphere reflection height is found to vary diurnally from ~65 km for the period 1000–1600 UTC to ~80 km for the period 2200–0400 UTC, from 1 June to 31 August 2013 inclusive. A similar magnitude of variation is also observed seasonally, with the ionosphere height for daytime in August 2013 being ~64 km and for December 2013 being ~76 km. No significan...
