Submesoscale Transition from Geostrophic Flows to Internal Waves in ADCP Data and 1/48-deg MITcgm: Implications for SWOT Mission [presentation]
Qiu, B., Nakano, T., Chen, S., Klein, P., Wang, J., Fu, L-L., and Menemenlis, D. (13-Dec-16). With the use of Ka-band radar interferometry, the SWOT satellite will improve the measured sea surface height resolution down to the spectral wavelength of 15km, allowing us to investigate for the first time the upper ocean circulation variability at the submesoscale range on the global scale. By analyzing repeat shipboard Acoustic Doppler Current Profiler measurements along 137°E, as well as the 1/48-deg MITgcm simulation output, in the northwest Pacific, we demonstrate that the observed/modeled upper ocean velocities are comprised of balanced geostrophic motions and unbalanced ageostrophic wave motions.

Transition Scale from Geostrophic Flows to Wave Motions in the World Ocean
PI: Bo Qiu (16-Jun-17). The overall goals of our project as part of the SWOT Science Team are, (1) to aid SWOT mission science preparation by evaluating spatio-temporal variability of SSH and surface velocity signals from available repeat ship-board ADCP measurements and high-resolution OGCM output from 1/48° MITgcm (llc 4320), and, (2) to advance our understanding of new upper ocean dynamics at O(5-200km) scales by analyzing high-resolution OGCM output and ADCP data, with the goal to maximize SWOT's scientific return.
Mesoscale / Sub-mesoscale Dynamics in the Upper Ocean

(18-Mar-15). This white paper mainly addresses some of the potential general science questions that can be addressed from the SSH signals observable with SWOT.
