Special Issue Information
Dear Colleagues,
This collection will focus on satellite and HF radar (High Frequency Radar) remote sensing of ocean surface currents, and the validation of these observations. Interest in the two-way coupling between winds and currents has grown enormously over the last decade. Ocean currents appear to play an important but neglected role in coupling the ocean and atmosphere, and recent modeling efforts suggest strong surface currents are far more plentiful than expected from earlier coarse resolution models and ocean re-analyses. Currents also greatly modify vertical motion in the upper ocean, and consequently influence vertical mixing in the upper ocean and the currents in the deep ocean. Observations of surface currents is extremely challenging, with most in situ measurements taken well below the surface, high frequency radar observations likely corresponding to depths of 1 to 2 m, and altimetry providing a time-averaged geostrophic current rather than a surface current. Theory and very limited observations indicate that there is a large difference between surface currents and currents just one meter below the surface. Concepts for simultaneous measurements of winds and currents using small modifications to available technology have been put forward in China, Europe, and the United States. The feasibility of measuring surface currents from satellite has been demonstrated through these efforts.
Papers that address the technology development towards satellite measurements of ocean surface currents are strongly encouraged, as are results for satellite and airborne campaigns. Additionally encouraged are papers on HF radar measurements of currents, and papers on the validation of either type of current measurement.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
