<p style="margin-top:0;margin-bottom:0">Dear Sir/Madam,</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0"><span>I am a PhD student in Geodesy at the University of Gävle, Sweden. As a part of my study, I need to use "<b>Mean Dynamic Topography</b>" data in combination with satellite gravimetry data. But the point is that the
<b>MDT</b> model should not be correlated with satellite gravimetry data (I have some models in which
<b>MDT</b> was calculated as the subtraction of Geoid height (by satellite gravimetry) and MSL(by satellite altimetry) so that they are not applicable for me). In other words, I need to utilize an
<b>MDT model</b> that is achieved purely from oceanographic observations.</span><br>
</p>
<p style="margin-top:0;margin-bottom:0"><span><br>
</span></p>
<p style="margin-top:0;margin-bottom:0"><span>I have heard that <b>ECCO-2 model</b> meet this assumption for me.</span></p>
<p style="margin-top:0;margin-bottom:0"><span>I just wanted to make sure whether or not I can use this model. What about
<b>ECCO-4</b>?</span></p>
<p style="margin-top:0;margin-bottom:0"><span><br>
</span></p>
<p style="margin-top:0;margin-bottom:0"><span>If one of these models/both of them can be used, I really appreciate it if you can help me to download the model(s) (I am a bit confused in the ftp address:
<a href="ftp://ecco.jpl.nasa.gov/" class="OWAAutoLink" id="LPlnk824912" previewremoved="true">
ftp://ecco.jpl.nasa.gov/</a> as I don't know which file I should download).</span></p>
<p style="margin-top:0;margin-bottom:0"><span><br>
</span></p>
<p style="margin-top:0;margin-bottom:0"><span>It's highly appreciated if you can help me.</span></p>
<p style="margin-top:0;margin-bottom:0"><span><br>
</span></p>
<p style="margin-top:0;margin-bottom:0"><span>Thank you so much in advance.</span></p>
<p style="margin-top:0;margin-bottom:0"><span><br>
</span></p>
<p style="margin-top:0;margin-bottom:0"><span>Best regards,</span></p>
