It's an incredibly exciting time for the Sea Level CCI project team. The first 3 years (2011 - 2013) of the project activities are now complete and a new chapter is underway taking the team into the next 3 year phase.   

The SLCCI project team during the end of Phase 1 / Kick Off to Phase 2 Meeting
held at ESRIN, Frascati, Italy (Feb 2014)


Some of the highlights of the first 3 years (Phase 1) include:

  • Definition of the users requirements for climate applications.
  • New algorithms have been developed in order to improve the altimeter measurements for climate applications (orbit solutions, geophysical corrections, instrumental corrections,...).
  • A formal validation protocol has been developed in order to estimate and validate the performances.
  • An international selection meeting has allowed the selection of the best algorithms.
  • More than 50 years of cumulated altimeter data have been processed, requiring an homogenised approach between altimeter missions.
  • Production of an 18 year-long time series (1993-2010) of sea level maps with associated climate indicators: global and regional mean sea level trends.
  • Assessment of the products by climate modelling groups.

A summary presentation of phase 1 is available (with the link below), describing several examples of improvements obtained with the Sea Level CCI dataset, affecting the trend of the global mean sea level, its inter annual evolution and an illustration of ENSO event.

 Looking forward to the next 3 years (Phase 2), the team will be focusing on: 

  • Refining the user requirements at climate scales.
  • Reducing the errors at some spatial and temporal scales.
  • Increasing the length of the time series and reducing the gap with present days with extensions and a full reprocessing of the dataset.
  • Improving the spatial coverage and reducing errors in coastal areas and in the Arctic region.
  • Integrating new altimeter missions.
  • Providing a sustainable system of production
