摘要

f层电离层的虚拟高度h 'F是一个重要的研究参数，以便深入了解其在一年中变化的情况。因此，在一年的数据集中采用多重分形形式，以深入了解以显著间歇性活动为特征的环境中发生的潜在物理过程。此外，应用于该数据的多重分形方法表明，测量不同尺度的间歇性现象是至关重要的。无论物理系统的能量来源如何，电离层始终呈现多重分形特征，包括日冕物质抛射（CME）、行星波（PW）、重力波（GW）等。这一证据表明，电离层也处于一种非平衡状态，类似于在磁层中观察到的状态。

Multifractal analysis of ionospheric F-layer dynamics at Jataí (lat. 17°52′. long. 51°43′), Brazil

The virtual height of the F-layer ionosphere,

h' F

, is an important parameter to study in order to gain insight into its variability over the course of a year. Accordingly, the multifractal formalism was employed over the course of a year’s data set to gain insight into the underlying physical processes occurring in an environment characterised by significant intermittent activity. Moreover, the multifractal approach applied to this data demonstrates that measuring intermittency phenomena at different scales is crucial. The ionosphere layer consistently exhibits multifractal characteristics, irrespective of the energy source of the physical system, including coronal mass ejection (CME), planetary waves (PW), gravity waves (GW), and others. This evidence indicates that the ionosphere layer is also in a state out of equilibrium system, similar to that observed in the magnetosphere.

期刊介绍： The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc. NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR). All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
