<p><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">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.<o:p></o:p></span></p>

<p><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">I just wanted to make sure whether or not I can use this model. What about
