<p class="MsoNormal">The heat budget should be closed as on daily fields, but your plot did show the residual is too large. If you haven’t done so, I would suggest you test your script using the monthly fields for the same grid cell. This may help narrow down
the cause of the problem.<o:p></o:p></p>

<p class="MsoNormal"><span lang="NO-BOK">Hi <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="NO-BOK"><o:p> </o:p></span></p>
<p class="MsoNormal">I am interested in looking at daily heat budgets in ECCOv4r4 and came across the documentation on computing heat budgets tailored for ECCOv4r3 monthly data.
<o:p></o:p></p>
<p class="MsoNormal">I was able to modify the Matlab script to work with daily data and for the period (2005 – 2015). However, the residual (LHS - RHS of the heat budget) is of comparable magnitude to the temperature tendency (LHS) (see attached figure for
a test grid cell). Maybe there is an error in my script which I overlooked (please see attached Matlab script). <o:p></o:p></p>
<p class="MsoNormal">I understand that ideally the residual should be just due to rounding errors as papers using the ECCO monthly data I have come across have closed heat budgets.
<o:p></o:p></p>
<p class="MsoNormal">Is the heat budget closed on daily timesteps? I would assume it is closed at each model timestep.
<o:p></o:p></p>
<p class="MsoNormal">Your assistance to help me close the daily heat budget will be highly appreciated.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Sincerely<o:p></o:p></p>
