Satellites
Sentinel-6 Michael Freilich, Sentinel-6 Next generation
Skills
Altimetry processing chain, uncertainty propagation, scientific expertise on sea level variation
Date
From 2021 to today
ASELSU project
ASELSU studies the possibility for the future Sentinel-6 Next Generation altimetry mission to meet the new requirements on sea level rise stability uncertainty. This project, funded by ESA, is led by Magellium with 4 other partners: CLS, LEGOS, NPL and UoR.

The objectives of ASELSU
-
-
- Justify the new uncertainty requirements of sea level rise stability for climate change studies
-
- Establish the end-to-end uncertainty budget of altimetry measurement at sea level rise following a metrological approach
-
- Provide tools to determine whether instrumental improvements to future altimetry missions would be useful and necessary to meet the requirements
