Atomic sensors metrology for long term and trustable monitoring of climate change Key Geodetic Parameters
Résumé
Establishing and maintaining a long term geodetic reference system is of key importance for climate monitoring and Earth observation systems. This long standing objective of the geoscience community is well supported by relevant international organisations. The need of better monitoring of critical parameters, such as ocean level, demands an improved accuracy of the global reference system down to the mm level, which constitutes the challenge to meet to evaluate accurately the cumulative impact of climate changes.
