  abstract = {{T}he {S}ea surface {KI}nematics {M}ultiscale monitoring ({SKIM}) satellite mission is designed to explore ocean surface current and waves. {T}his includes tropical currents, notably the poorly known patterns of divergence and their impact on the ocean heat budget, and monitoring of the emerging {A}rctic up to 82.5 {N}. {SKIM} will also make unprecedented direct measurements of strong currents, from boundary currents to the {A}ntarctic circumpolar current, and their interaction with ocean waves with expected impacts on air-sea fluxes and extreme waves. {F}or the first time, {SKIM} will directly measure the ocean surface current vector from space. {T}he main instrument on {SKIM} is a{K}a-band conically scanning, multi-beam {D}oppler radar altimeter/wave scatterometer that includes a state-of-the-art nadir beam comparable to the {P}oseidon-4 instrument on {S}entinel 6. {T}he well proven {D}oppler pulse-pair technique will give a surface drift velocity representative of the top meter of the ocean, after subtracting a large wave-induced contribution. {H}orizontal velocity components will be obtained with an accuracy betterthan 7 cm/s for horizontal wave lengths larger than 80 km and time resolutions larger than 15 days, with a mean revisit time of 4 days for of 99% of theglobal oceans. {T}his will provide unique and innovative measurements that will further our understanding of the transports in the upper ocean layer, permanently distributing heat, carbon, plankton, and plastics. {SKIM} will also benefit from co-located measurements of water vapor, rain rate, sea ice concentration, and wind vectors provided by the {E}uropean operational satellite {M}et{O}p-{SG}({B}), allowing many joint analyses. {SKIM} is one of the two candidate satellite missions under development for {ESA} {E}arth {E}xplorer 9. {T}he other candidate is the {F}arinfrared {R}adiation {U}nderstanding and {M}onitoring ({FORUM}).{T}he final selection will beannounced by {S}eptember 2019, for a launch in the coming decade.},
