Hi, support group,<br>
<br>
I hope this message finds you well. I am interested in using the ECCO v4r4 data, I was hoping you might be able to offer some guidance.
<br>
I know that ECCO has datasets on PO.DAAC(<a href="https://podaac.jpl.nasa.gov/ECCO?tab=mission-objectives§ions=about+data">https://podaac.jpl.nasa.gov/ECCO?tab=mission-objectives§ions=about%2Bdata</a>) and in the ECCO Drive Web Interface (<a href="https://ecco.jpl.nasa.gov/drive/files/Version4/Release4/">https://ecco.jpl.nasa.gov/drive/files/Version4/Release4/</a> ),
but the data names and directory organization are quite different from those. I was wondering if there are any differences in the data downloaded from these two different locations, especially the OBP data I'm interested in.<o:p></o:p></span></p>
