<p class="MsoNormal">Good morning team, <o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I am a PhD student at Brown University, and I study the dynamics of the near-surface circulation in the Arctic Ocean. As part of one of the projects, I am trying to make an intercomparison between the ECCO sea ice products (e.g., sea ice
velocity, thickness, drift speed, curl, angle) with other reanalysis products (e.g., NSIDC, OSI-SAF).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">To make this comparison, I need to convert the Arctic cap into a WGS-84 geocentric coordinate system. Because the coordinate reference system (CRS) for the rest of the products is WGS-84, and I want the ECCO to be the same for a perfect
comparison. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I did not find any document that might allow me to make this conversion. Could you kindly help me with this? I would really appreciate any feedback from you!<o:p></o:p></p>
