LAP data products


Langmuir probe (LAP) onboard CSES is the space plasma in-situ detection payloads  The scientific objective of the LAP is to study space plasma physics phenomena and ionospheric changes caused by seismic events, magnetic storms, etc. The LAP can measure electron density (Ne) over a range from 5×102~1×107 cm–3, and electron temperature (Te) from 500 K to 10,000 K with relative measurement accuracy of 10%. It is also capable of monitoring the spacecraft potential and its variations.
