Hi all, I am using NEMOv4.0.4 and I am trying to output the zonally and depth integrated poleward heat transport, i.e. the variable called sophtvtr and also sopht\_vt\_bsn in case it is split per basin. NEMO is producing… --- ## [Creating NEMO output diagnostics](https://nemo-ocean.discourse.group/t/creating-nemo-output-diagnostics/446)

Hi there, I would like to create my own output diagnostics for NEMO, which could be for example, density, or Froude and Rossby numbers. But first I am trying to figure out how nemo calls and outputs current diagnostics,… --- ## [Global masked summation over domain for 2D array](https://nemo-ocean.discourse.group/t/global-masked-summation-over-domain-for-2d-array/344)

Dear All, I am trying to code some diagnostic in Nemo, and for that I need to do mpp\_sum on a 2D array. Meaning that mpp\_sum would need to sum each member i,j of the array separately among all the processors. But I can… --- ## [\[v4.2.x\]\[v4.0.x\] Mixed layer depth \`mldr10\_3\` not initialized](https://nemo-ocean.discourse.group/t/v4-2-x-v4-0-x-mixed-layer-depth-mldr10-3-not-initialized/230)

Hi all, I am using NEMOv4.0.4 and I came across an issue when trying to output the variable mldr10\_3 (mixed layer depth diagnosed from vertical density gradient of 0.03 kg.m-3 with respect to the 10m deep layer).

Hello, I am using NEMO4.0.4 on ORCA1 and I struggle in outputting the variables msftbarot and uocetr\_vsum\_cumul. When I include these variables in the file\_def\_nemo-oce.xml my simulation crashes with this error message: … --- ## [\[v4.0.x\]\[v3.6\] M2 harmonic bias due to nodal corrections applied to tidal forcing](https://nemo-ocean.discourse.group/t/v4-0-x-v3-6-m2-harmonic-bias-due-to-nodal-corrections-applied-to-tidal-forcing/157)

Dear all, I am currently using the harmonic analysis of tidal constituents implemented in NEMO (key\_diaharm). I was wondering if this module was recoded in another language (python for example) or if a standalone versio…
