“…At present, the main source of uncertainty in our retrieval of the surface current is due to the uncertainty on U WD . At Ka-band and for incidences less than 20 • , U WD is of the order of 25 times the radial component of the surface Stokes drift U S (Nouguier et al, 2018;Yurovsky et al, 2018), and U S is approximately 1.2% of the radial wind component (Rascle et al, 2006); (Peureux et al, 2018).…”

“…These are particularly important at high latitudes. Development in the understanding of radar echoes from the oceans in Ka-band (Yurovsky et al, 2017), allowing higher resolution measurements, and of Doppler measurements in general (Chapron et al, 2005;Yurovsky et al, 2018) show that it is feasible to measure surface currents more directly. Responding to a fast-track call from the European Space Agency, SKIM leverages the development of near-nadir instruments such as SWIM (Hauser et al, 2017) with addition of Doppler processing.…”

“…This representation could question the sea spikes behavior since high velocities can be found for moderate level of NRCS. The analysis proposed here is limited to HH polarization, but similar representations and remarks are given in Yurovsky et al (2018) for high grazing angles, considering both HH and VV polarization.…”

“…2018, 10, x FOR PEER REVIEW 7 of 24 could be as large as 0.14 m/s for a wind speed error of 2 m/s, and could reach values smaller than 0.40 m/s for wind direction errors smaller than 20° in the crosswind direction. In addition, wind speed in the Ka-band will experience a saturation beginning at 15 m/s [20]. The Ka-band geophysical model function (GMF) indicates that the saturation is somewhere above 15-20 m/s, as the GMF follows the observation and the theoretical power law well, while the airborne results suggest that it will function better than the GMF theory [21], which may due to the deeper penetration of the airplane observations.…”
