Short summary
Sea level is a key indicator of climate change and has been monitored by satellite altimetry for more than 2 decades. The evaluation of the performances of the altimeter missions can be performed by comparison with in situ-independent measurements from Argo profiling floats. This allows for the detection of altimeter drift and the estimation of the impact of a new altimeter standard. This study aims at characterizing the errors of the method thanks to sensitivity analyses to different parameters.
