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

      The partners

      Laboratory for Geophysical and Oceanographic Space Studies (LEGOS), Collection Localisation Satellites (CLS), British National Physical Laboratory (NPL), University of Reading (UoR)
