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? Bartholome ---

If the [CSIRO data portal](https://data.csiro.au/collection/csiro:51902) 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 ---

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. pearse ---

ahah, I did not expect less from you! Thanks!
