<p class="MsoNormal">Good news! You can access the daily THETA and SALT fields from ECCO V4r4 using the command. The files are hosted on NASA’s PO.DAAC. Instructions can be found from V4r4 product page,

<br>
I know that the ECCO data portal has been down for a few weeks. However, I noticed that it is possible to download daily data from the NAS ECCO Data Portal (<a href="https://urldefense.us/v3/__https:/data.nas.nasa.gov/ecco/data.php?dir=*eccodata*llc_90*ECCOv4*Release4__;Ly8vLw!!PvBDto6Hs4WbVuu7!cxlQMcOwyHg7zAUsaWpjryFMaXPfI3OTqbdYZBepbMYMutmCP7aUzDDpGb4gcdcZCtyT$">https://data.nas.nasa.gov/ecco/data.php?dir=/eccodata/llc_90/ECCOv4/Release4</a>).
I would like to download the daily THETA variable and the daily Salt variable, without downloading each daily file individually. Is there a UNIX-based command for that? I have tried:<o:p></o:p></span></p>

But that does not work. So, what is the best way to download the data?<br>
I thank you in advance for any help provided.<br>
