Daria or Hong, would you have looked at MXLDEPTH depth in the
“cube92” solution?

<div class="">John, why not use the ECCO-V4, which is
data-constrained?</div>

<div class="">ECCO v4 is on a 1-degree grid, which is closer to
your desired 2x2 degree grid.</div>

<br class="">
I would like to make use of the Mixed-Layer
Depth model outputs from the global model
runs 1992-present (Nov. 2016) to drive some
simple 1D biogeochemical models for CDOM. I
have binned to model outputs from the jpg
site into monthly 2x2 deg. grids. One thing
of concern that I have is the trends in the
global MLDs (see attached figure), which are
more extreme in the SO. Is there an issue
with maintaining correct ocean boundary
layers, esp. in the SO for this model? Has
this been observed yet?<br class="">

<font size="2">Hi John,<br>
You're right, MLD from cube92 run has bias in late stage<br>
because it's a free run for the later period.<br>
As Dimitris said, you can look at other ECCO product provided at
the website.<br>
Please see attached fig showing MLD from ECCOv4 and ECCO llc270
for an example,<br>
where red line is for ECCOv4 (1992-2012) and blue line for ECCO
llc270 (2001-2015) in upper plot<br>
also MLD for cube92 is also shown in lower plot for reference.<br>

cheers<br>
