We present a new method with a Graphical User Interface (GUI), allowing to inspect 15 years of Cluster mission (2002-2017) to derive plasmapause positions (PP).
The PP are deduced from electron density data derived from WHISPER relaxation sounder wave measurements, which is limited up to around 150 cm-3.
It is important to note that our approach allows us to identify the PP during geomagnetically quiet periods, which is a challenging issue as during such periods plasmapause becomes diffused and its boundary can be hard to determine.
After reviewing and validating the PP, we obtained a dataset containing more than 4000 PP positions.
It is our objective that this dataset will eventually become available as a high-level data product in the Cluster Science Archive (CSA).
The obtained PP dataset can be very valuable for future studies of plasmapause formation and evolution, as well as interaction with the radiation belts. This can contribute to improving understanding of space weather's impact on the Earth's magnetosphere.
