Problems with the organic matter and phytoplankton modules

[Gabriela Gomes Nogueira Sales]

Hi everybody!

I'm having problems simulating the organic matter and phytoplankton modules together, more specifically in the parameters: p_excretion_target_variable = 'OGM_dop' and n_excretion_target_variable = 'OGM_don'.

This error appears to me:

When I comment these parameters, the model runs normally.

Does anyone know what may be happening?

Ps: in this simulation I am also running oxygen, nitrogen and phosphorus.

Best regards,

Gabriela

Hi Gabriela,

It seems like you are running the module &aed2_organic_matter, otherwise the model can't connect your phytoplankton with OGM_dop and OGM_don. Is your organic_matter module linked to carbon dynamics? Because it seems you're not including &aed2_carbon and the variable CAR_dic. Which version of GLM and AED2 are you using?

Best,

Robert

Hi Robert,

Thank you so much for answering me!

I really wasn't running the carbon module in my simulation. The modules that were enabled were only & aed2_tracer, & aed2_oxygen, & aed2_nitrogen, & aed2_phosphorus, & aed2_organic_matter, & aed2_phytoplankton and & aed2_totals.

But after your question, I did some tests by activating the carbon module. Ultimately, the model ran normally (without errors) by adding only the parameter c_excretion_target_variable = 'OGM_doc' in the phytoplankton module, without even having to activate & aed2_carbon.

However, the results are the same as the simulation in which I disable the parameters p_excretion_target_variable = 'OGM_dop' and n_excretion_target_variable = 'OGM_don, as I mentioned earlier.

The version I'm using GLM is 3.0.5 and AED is 1.3.2.

Best regards,

Gabriela
