SKIM
ESA-EE9 candidate satellite mission

Sea surface kinematics multiscale monitoring (SKIM) was one of the two candidate missions for the 9th Earth Explorer mission of in the FutureEO programme of the European Space Agency (ESA). SKIM and the other candidate (FORUM) were pre-selected for a detailed study in November 2017. Only one of the two candidates was to be selected in 2019 for immediate implementation and a possible launch by the year 2025, and FORUM was chosen.
Context
SKIM builds on the technological heritage of the SWIM instrument now flying on the China-France Ocean Satellite, with the important addition of Doppler measurement and changing from Ku to Ka-band. SKIM also inherits experience with Ka-band altimetry from the Indian-France SARAL-AltiKa mission.
Scientific Objectives
The mission's science goals are to
determine how the dynamics of the ocean total surface current velocity influence the integrated Earth system
more specifically,
Determine the transport by waves and currents of material at the ocean surface including plankton, nutrients, heat, carbon, oil, and marine plastic debris
Map and apply currents and its components to generate better estimates of atmosphere–ocean exchanges of heat, gas, momentum and energy accounting for the full interplay between the surface ocean and the lower atmosphere (including upper ocean mixing)
The satellite will overfly Earth from 83°S to 83°N, covering at least 97 percent of the globe.
Begin with the source’s own compact description: “SKIM” is eSA-EE9 candidate satellite mission. The dossier treats that line as a proposition to test through SKIM, ESA-EE9 and candidate, not as a finished interpretation.
Why this record matters
The phrase “eSA-EE9 candidate satellite mission” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 9, 2026. The linked authority identifier is Q65122234. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2017, 2019 and 2025.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
