Short summary
The reference mean sea level (MSL) record, essential for understanding climate evolution, is derived from the altimetric measurements of the TOPEX/Poseidon mission, followed by Jason-1 and later Jason-2 on the same orbit. Soon, Jason-3 will be launched on the same historical orbit, followed by Sentinel-3a on a new one. This paper shows linking missions with the same orbit enables meeting climate user requirements regarding the MSL trend while using Sentinel-3a would increase the uncertainty.
