Hi all,<br>
I am trying to find out how I can get the monthly averaged output of<br>
adjoint sensitivity in ECCOv4.<br>
<br>
I got the snapshot output of adjoint sensitivity from ADJ*** files.<br>
However, there seems no time-averaged output under regular settings. I saw<br>
there are "adxx_" files with the default time frequency of 1209600s, which<br>
is 2 weeks. Are the records in "adxx_" files the time-averaged output of<br>
adjoint sensitivity? If not, is there any other way to get the<br>
time-averaged output of adjoint sensitivity in ECCOv4?<br>
<br>
Thanks,<br>
Xiaohui Liu<br>

Hi Xiaohui,<br>
<br>

Correct on both counts.<br>
<br>
> Are the records in "adxx_" files the time-averaged output of adjoint sensitivity?<br>
Yes.<br>
<br>

I believe the solution here may involve changing xx_gentim2d_period and maybe activating new control terms via data.ctrl (you may need to provide xx files filled with zeros to do this) so that the adxx output suits your needs. There is documentation about these features @ <a href="https://mitgcm.readthedocs.io/en/latest/ocean_state_est/ocean_state_est.html" rel="noreferrer" target="_blank">https://mitgcm.readthedocs.io/en/latest/ocean_state_est/ocean_state_est.html</a> <<a href="https://mitgcm.readthedocs.io/en/latest/ocean_state_est/ocean_state_est.html" rel="noreferrer" target="_blank">https://mitgcm.readthedocs.io/en/latest/ocean_state_est/ocean_state_est.html</a>><br>
<br>
Hope this helps.<br>
<br>
Cheers,<br>

Forgot to mention that for state variables you should be able to use the diagnostics package now; see section 9.1.4.2. @ <a href="https://mitgcm.readthedocs.io/en/latest/outp_pkgs/outp_pkgs.html#pkg-diagnostics-a-flexible-infrastructure" rel="noreferrer" target="_blank">https://mitgcm.readthedocs.io/en/latest/outp_pkgs/outp_pkgs.html#pkg-diagnostics-a-flexible-infrastructure</a> <<a href="https://mitgcm.readthedocs.io/en/latest/outp_pkgs/outp_pkgs.html#pkg-diagnostics-a-flexible-infrastructure" rel="noreferrer" target="_blank">https://mitgcm.readthedocs.io/en/latest/outp_pkgs/outp_pkgs.html#pkg-diagnostics-a-flexible-infrastructure</a>><br>
