A technique is proposed to measure the electron density profile of the ionosphere between 100 and 800 km using a microwave frequency receiver on board a conventional Earth Observations Satellite and a series of transmitters on micro satellites in appropriate orbits. A pair of pulsed frequencies will enable the relative signal delay to be determined and hence the total electron content between the two devices. The vertical profiles of N along the satellite track can be retrieved using a modified form of tomography. Regular global coverage from a single experiment over several years would provide a unique data set for comparison with models of the ionosphere, and also its interaction with the neutral atmosohere and its response to changes in solar activity.

提出了一种利用传统地球观测卫星上的微波频率接收器和适当轨道上的微型卫星上的一系列发射机测量100 ~ 800 km电离层电子密度剖面的技术。一对脉冲频率将能够确定相对信号延迟，从而确定两个器件之间的总电子含量。N沿卫星轨道的垂直剖面可以使用一种改进的层析成像形式来检索。几年来进行的一次定期的全球覆盖试验将提供一个独特的数据集，用于与电离层模型、电离层与中性大气的相互作用以及电离层对太阳活动变化的反应进行比较。

By comparing direct measurements taken from onboard Atmosphere Explorer spacecraft (AE), in eccentric orbit, with incoherent scatter radar (ISR) measurements taken from the ground, we illustrate both the merits and the difficulties involved in such comparisons. Five altitude profiles of ionization determined from AE, in near coincidence with ground stations making ISR measurements, compared favorably with the ISR data so long as the AE measurements were properly analyzed for the effects of variations in latitude and solar zenith angle along the spacecraft orbit.

通过比较偏心轨道上大气探测器(AE)的直接测量结果与地面的非相干散射雷达(ISR)测量结果，我们说明了这种比较的优点和困难。从声发射确定的电离的5个高度剖面图与进行ISR测量的地面站几乎一致，只要正确地分析了沿航天器轨道的纬度和太阳天顶角变化的影响，就可以与ISR数据进行比较。

Lightning transient fields in the atmosphere—low ionosphere 大气低层电离层中的闪电瞬变场
Journal of Atmospheric and Terrestrial Physics
Pub Date : 1996-11-01 DOI: 10.1016/0021-9169(95)00154-9

The complexity of the electric properties of the atmosphere, which influences the excitation and propagation of electromagnetic signals generated by lightning discharges, gives rise to a diversity of the typical signal wave forms and amplitudes in the various space-time domains. This causes difficulties and controversies in the interpretation of the experimental data. In geophysical problems of such a kind, considerations accounting for a broadband spectrum are particularly important.

In the present paper, lightning induced ULF-VLF fields in the daytime inhomogeneous atmosphere and D-region of the ionosphere above the thundercloud are analyzed for a standard model of the vertical return stroke. The developed analytical approach makes it possible to unite the canonical model of the electromagnetic radiation into a free-half-space, the discharge (ELF-VLF spectrum) and ‘post-discharge’ (ULF spectrum) low-frequency models and to clarify the temporal scales in the mechanism of lightning coupling with the atmosphere and low ionosphere with respect to the local relaxation time, discharge characteristic time scales and observer location.

大气电特性的复杂性影响着雷电放电产生的电磁信号的激发和传播，导致在不同时空域中典型信号波形和振幅的多样性。这就给实验数据的解释带来了困难和争议。在这类地球物理问题中，考虑宽带频谱是特别重要的。本文分析了雷雨云上方电离层d区和非均匀大气中白天雷击诱发的超低频场。该分析方法将电磁辐射的标准模型统一为自由半空间、放电(ELF-VLF谱)和放电后(ULF谱)低频模型，阐明了闪电与大气和低电离层耦合机制的时间尺度，包括局部松弛时间、放电特征时间尺度和观测者位置。

Atmospheric CO2 changes at Mauna Loa, Hawaii 夏威夷莫纳罗亚的大气二氧化碳变化

The 12-month running mean series of atmospheric CO2 directly measured at Mauna Loa, Hawaii, showed highly significant periodicities near T = 14, 8, 5, 3–4 years. This CO2 series also showed a significant oscillation at T = 2.56 years which matches with T = 2.6 years of the Southern Oscillation (SO) index but not with the QBO (T = 2.33 and 2.68 years) of the stratospheric zonal wind. On the other hand, the yearly range (maximum minus minimum) series of CO2 showed periodicities T = 2.45 and 2.75 years (significant at the 2 sigma level) which seem similar to those of the stratospheric wind QBO (T = 2.33 and 2.68 years). No evidence was found for a 11 year (solar cycle) component.

在夏威夷莫纳罗亚直接测量的12个月的大气CO2平均序列在T = 14、8、5和3-4年附近显示出高度显著的周期性。该CO2序列在T = 2.56年也表现出显著的振荡，与南方涛动(SO)指数的T = 2.6年相匹配，但与平流层纬向风的QBO (T = 2.33和2.68年)不匹配。另一方面，CO2的年变化幅度(最大值-最小值)序列表现出T = 2.45和2.75年的周期性(在2 σ水平上显著)，这与平流层风QBO的周期性(T = 2.33和2.68年)相似。没有证据表明存在11年(太阳周期)的成分。
