Advanced Ionospheric Probe (AIP) is provided by Graduate Institute of Space Science, National Central University (NCU) for the FORMOSAT-5 satellite as a scientific payload. The AIP is an all-in-one plasma sensor with sampling rate up to 8,192 Hz to measure ionospheric plasma concentrations, velocities, and temperatures over a wide range of spatial scales. Once a comprehensive dataset is available from the AIP, a systematic examination of longitudinal and seasonal variations of the ionospheric parameters in the topside F region can be conducted for all latitudinal coverage. The transient and long-term variations of ionospheric plasma can be monitored in the upcoming solar maximum period and are beneficial to predict the trend of the space weather as well as the seismic precursors associated with earthquakes. <_Description>Source: Master/CDFglobalAttributes/TEXT <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ https://www.eoportal.org/satellite-missions/formosat-5 overview FormoSat-5 mission <_Note>URL also in all.xml.
