<div>Dear EECO suport team,</div><div><br></div><div> I am Yao Yu, a graduate student in China. I am writing to inquire about the assimilation of altimetry SSH in the ECCO V4R3 OGCM.<br></div><div><br></div><div> I
am using satellite altimetry measurements, GRACE measurements and two
OGCMs (GLORYS2V4 and ECCO V4R3) to analyze an oceanic gyre in the
Argentine Basin. However, ECCO failed to reproduce the sought-after
feature (~25-day, ~500 km) while the three others could. I am trying to
figure out the reason. I have read about the datasets used in ECCO
(<a href="ftp://ecco.jpl.nasa.gov/Version4/Release3/doc/v4r3_data.pdf" target="_blank">ftp://ecco.jpl.nasa.gov/Versi<wbr>on4/Release3/doc/v4r3_data.pdf</a><wbr>) and then
Forgot and Ponte (2015) for details about altimeter data. </div><div><br></div><div>I'd be grateful if you can help to answer my questions:<br></div><div><div><br></div><div>1.
Are there any spatial (except for the bin-averaging) and temporal
smoothing schema applied to altimeter data?
I don't think the
nominal 1-degree spatial resolution of ECCO is coarse, however,
ECCO's SSH look quite coarse (comparable with GRACE, ~300km) in the Argentine Basin.<br></div><div><br></div><div>2.
If the answer is no for question 1, then are there any possible reasons
that can explain inability of ECCO over the Argentine Basin?<br></div><div><br></div><div>Many thanks!</div><div class="m_3740370825578346599gmail-yj6qo m_3740370825578346599gmail-ajU"><div id="m_3740370825578346599gmail-:16u" class="m_3740370825578346599gmail-ajR"><img class="m_3740370825578346599gmail-ajT" src="https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif"></div><span class="HOEnZb"><font color="#888888"><div class="m_3740370825578346599gmail-ajR">Yao<br></div></font></span></div></div>
