PWS (Plasma Wave Detector and Sounder) onboard the Akebono (EXOS-D) satellite has three sub-systems; i.e. i) a sub-system for natural plasma wave observations (NPW), ii) a sub-system for stimulated plasma wave experiments (SPW) and iii) the instrumentation for measurement of the number density of electron (NEI).

This dataset contains the topside ionogram data observed by SPW sub-system operated in n2, n3, and h3 modes. The frequency range, number of frequency step, sweep period, range resolution in vacuum, and number of sample data in these mode operations are as follows:

Data Analysis

Here, you can find a TDAS load procedure file for PWS electric field intensity spectrum data. PWS electric field intensity spectrum data analysis becomes available on TDAS with this load procedure. TDAS (THEMIS Data Analysis Software suite) has been developed by THEMIS project. See TDAS web page for details.

If you have any questions or request for the data, please contact DARTS.
