<span style="line-height: normal;">I am Haohao Zhang from the Institute of Atmospheric Physics, Chinese Academy of Sciences. I am currently participating in a project focusing on the
</span> the evaluation of ocean heat content in reanalysis datasets <span style="line-height: normal;">
with Chunxue Yang and Andrea Storto (CNR-ISMAR, Italy).</span></div>

</div>
<div class="ms-outlook-mobile-reference-message skipProofing" style="line-height: 1.5; font-family: 微软雅黑; font-size: 16px;">
We would like to include the ECCO datasets (might be the ECCOv4r5 and ECCOCube92) in our work. We noted from the website that the temporal coverage for ECCOv4r5 currently ends in 2019, and ECCOcube92 extends to 2024. Therefore, I am writing to inquire about
the latest status of these two datasets. If more recent updates are available, would it be possible for us to gain access to them?</div>
