Particular detritus comparison in PI and LIG

COSIMA Biogeochemistry

Hello all,
I am currently after comparing particular detritus at 250m in PI and LIG simulations (ACCESS-ESM). In PI, I found the variable detoc (Detrital Organic Carbon Concentration) in mol/m3 while I found det (no caption) in mmol/m3 in LIG output. After plotting and converting units, detoc is about x8 greater than det so I think the two variables don’t really match. Is it related with a unit mismatch that I have not noticed? If not, is there any other variable that is more relevant for the comparison of particular detritus in PI and LIG simulation?

If the CSIRO data portal is to be believed @tiloz, @LaurieM and @nyeung might be able to help.

Hello Bartholome,

We can discuss this tomorrow or Friday at the CCRC.

Best,
Laurie

Cool, but if you do find out something useful it would be great to post that information back into this thread so others can find out the answers in the future.

Thanks!

The issue was that the raw outputs of detritus from the ACCESS-ESM1.5 are in mmol of N, whereas the CMORized data is in mol of C.

Maybe I should add that to avoid mistakes it would be great if the WOMBAT outputs for variables linked to primary production (i.e. NPP, gross phytoplankton, detritus…) could include precise units, i.e. specify if it is mol of C, N, P… @pearseb
Thanks!

Way ahead of you! this shouldn’t be an issue in the future.
Everything from now on will be in C units, and this will be explicit in the netcdf attribute output.
