Similar Data Retrieval from Enormous Datasets on ELF/VLF Wave Spectrum Observed by Akebono
As the total amount of data measured by scientific spacecraft is drastically increasing, it is necessary for researchers to develop new computation methods for efficient analysis of these enormous datasets. In the present study, we propose a new algorithm for similar data retrieval. We first discuss key descriptors that represent characteristics of the VLF/ELF waves observed by the Akebono spac...
متن کاملStudy on Dispersion Characteristics of Lightning Whistlers Observed by the Akebono Satellite
It is well known that electron density profile in the geospace changes day by day and thus remote sensing techniques using electromagnetic waves are recently highlighted as a powerful tool, because they are useful for obtaining the global electron density profile in the earth’s plasmasphere with high time resolution. We have been developing tomographic techniques using information of propagatio...
متن کاملStudy of Dispersion of Lightning Whistlers Observed by Akebono Satellite in the Earth's Plasmasphere
When the Akebono (EXOS-D) satellite passed through the plasmasphere, a series of lightning whistlers was observed by its analog wideband receiver (WBA). Recently, we developed an intelligent algorithm to detect lightning whistlers from WBA data. In this study, we analyzed two typical events representing the clear dispersion characteristics of lightning whistlers along the trajectory of Akebono....
متن کاملOn the occurrence of ground observations of ELF/VLF magnetospheric amplification induced by the HAARP facility
[1] The ionospheric heating facility of the High Frequency Active Auroral Research Program (HAARP) has been used extensively in the last 3 years for injection of ELF/VLF waves into the magnetosphere via modulated heating of the overhead auroral electrojet currents. Of particular interest are waves that are observed to be nonlinearly amplified after interaction with hot plasma electrons in the E...
متن کاملObservations of ionospheric ELF and VLF wave generation by excitation of the thermal cubic nonlinearity.
Extremely-low-frequency (ELF, 3-3000 Hz) and very-low-frequency (VLF, 3-30 kHz) waves generated by the excitation of the thermal cubic nonlinearity are observed for the first time at the High-Frequency Active Auroral Research Program high-frequency transmitter in Gakona, Alaska. The observed ELF and VLF field amplitudes are the strongest generated by any high frequency (HF, 3-30 MHz) heating fa...
