In the framework of the ESA SING project, multiple sets of synthetic datasets have been produced to evaluate the scientific performance of future satellite gravimetry missions. The production pipeline follows a three-tier integrated architecture:
High-resolution synthetic Earth system model (AOHISBED). Two versions of the ESA Earth System Model have been used: ESM 2.0 and its upgraded version ESM 3.0, developed within the framework of the SING project.
Closed-loop simulations retrieving global gravity field solutions at various spatio-temporal resolutions for future satellite constellations.
Thematic product prototypes for operational services and data assimilation products (hydrology, ocean, cryosphere, solid Earth, geodesy) for scientific impact studies.
Two Data Generations: A first generation based on the ESM2.0 reference model has already been released. A new generation based on the upgraded ESM3.0 model has been generated and will be available soon.
