<p class="MsoNormal">You can follow the budget calculation document evaluating_budgets_in_eccov4r3.pdf by Christopher G. Piecuch<o:p></o:p></p>
<p class="MsoNormal">(<a href="https://ecco.jpl.nasa.gov/drive/files/Version4/Release3/doc/evaluating_budgets_in_eccov4r3.pdf">https://ecco.jpl.nasa.gov/drive/files/Version4/Release3/doc/evaluating_budgets_in_eccov4r3.pdf</a>). All of the necessary variables
can be found in <a href="https://ecco.jpl.nasa.gov/drive/files/Version4/Release3/">
https://ecco.jpl.nasa.gov/drive/files/Version4/Release3/</a> as described in the document. Most of the variables are in the

<p class="MsoNormal">Two things to note here:<o:p></o:p></p>
<p class="MsoNormal">1) The ECCO ftp server has been replaced with ECCO Drive as announced to the ecco-support mailing list in early August. Please replace
<a href="ftp://ecco.jpl.nasa.gov">ftp://ecco.jpl.nasa.gov</a> in URLs with <a href="https://ecco.jpl.nasa.gov/drive/files">https://ecco.jpl.nasa.gov/drive/files</a>. ECCO Drive requires users to first register for a NASA’s Earthdata account at
<a href="https://urs.earthdata.nasa.gov/users/new">https://urs.earthdata.nasa.gov/users/new</a> in order to access the ECCO products.<o:p></o:p></p>
<p class="MsoNormal">2) The interp_monthly directory, <a href="ftp://ecco.jpl.nasa.gov/Version4/Release3/interp_monthly/">
ftp://ecco.jpl.nasa.gov/Version4/Release3/interp_monthly/</a> in your email (i.e.
<a href="https://ecco.jpl.nasa.gov/drive/files/Version4/Release3/interp_monthly">
https://ecco.jpl.nasa.gov/drive/files/Version4/Release3/interp_monthly</a> for ECCO Drive) contains the interpolated fields on a regular grid. These interpolated fields cannot be used to compute budgets because of errors introduced in interpolation. One has
to use the fields on the native grid (<a href="https://ecco.jpl.nasa.gov/drive/files/Version4/Release3/nctiles_monthly/">https://ecco.jpl.nasa.gov/drive/files/Version4/Release3/nctiles_monthly/</a>) for budget calculations.

<p>Dear Support team,<o:p></o:p></p>
<p>I am willing to compute heat budget using ECCOv4 (Release3) . I started to follow the nice tutorial (<a href="https://ecco-v4-python-tutorial.readthedocs.io/ecco_budgets.html">https://ecco-v4-python-tutorial.readthedocs.io/ecco_budgets.html</a>). It starts
with the open_mdsdataset function to load the data, <o:p></o:p></p>
<pre><span class="n">ds_ave</span> <span class="o">=</span> <span class="n">open_mdsdataset</span><span class="p">(</span><span class="s1">'/rigel/ocp/users/jt2796/ECCO_v4_r2/run_budg3d_1yr/'</span><span class="p">,</span><o:p></o:p></pre>
<pre> <span class="n">delta_t</span><span class="o">=</span><span class="mi">3600</span><span class="p">,</span> <span class="n">ref_date</span><span class="o">=</span><span class="s1">'1991-12-15 12:0:0'</span><span class="p">,</span> <span class="n">geometry</span><span class="o">=</span><span class="s1">'llc'</span><span class="p">,</span><o:p></o:p></pre>
<pre> <span class="n">prefix</span><span class="o">=</span><span class="p">[</span><span class="s1">'monave2d'</span><span class="p">,</span><span class="s1">'monave3d'</span><span class="p">])<o:p></o:p></span></pre>
<p>but I am not too sure what should be the actual files targeted under the given directory (format?). Should it contain all the variables such as in
<a href="ftp://ecco.jpl.nasa.gov/Version4/Release3/interp_monthly/">ftp://ecco.jpl.nasa.gov/Version4/Release3/interp_monthly/</a> ? I have tried many options, but never seems to make it work. The error I get is "Couldn't find RC.meta file to infer nz.", so
I am guessing it is grid-related...<o:p></o:p></p>
<p>Sorry if I am missing something here. Thank you for your help,<o:p></o:p></p>
<p>Damien<o:p></o:p></p>
