[PEM16-02] Plasma Wave Experiment (PWE) on board the ARASE (ERG) Satellite (Initial Report)
Keywords:Plasma Wave Experiment (PWE), Arase (ERG), Inner Magnetosphere, Chorus, EMIC, Ground data processing
The PWE will generate two kinds of mission data; nominal data and burst data. The former consists of wave spectra in VLF/HF range and waveforms in ELF range, and will be generated continuously as survey data. The nominal data will be downloaded to the ground. On the other hand, the latter is essentially raw waveform data in VLF range and the data amount is quite huge. They will be once stored in the mission data recorder (MDR) and partial data will be downloaded after data selection. In order to obtain maximum science output, it is very important to check and analyze the nominal data quickly and select valuable data from burst data stored in the MDR.
The ARASE has passed its critical operation phase and we have confirmed successful extension of the wire-probe antennas as well as the masts. The onboard instruments including the PWE are now in the initial check out phase. In the present paper, we introduce the specification of the PWE and its initial data. We also introduce our data processing plan on the ground.
