[BUG] Error in AERmon variables

[oyvindseland]

Error in AERmon variables dryss and dryoa. Must be retracted and republished. Not all output fields included.
dryso4 and drybc correct.

Simulations: AerChemMIP, RFMIP and CMIP

Corrected in the table but also included here

dryss: SS_A1DDF + SS_A2DDF + SS_A3DDF +SS_A1_OCWDDF + SS_A2_OCWDDF + SS_A3_OCWDDF

dryoa: OM_ACDDF + OM_AIDDF + OM_NIDDF +OM_AC_OCWDDF + OM_AI_OCWDDF + OM_NI_OCWDDF

@øyvind

I think we maybe have to change the expression for dryoa and wetoa, and include the contribution from SOA_A1 and SOA_NA dry and wet depostion. In mmroa (which is used by many people to calculate the burden en then the lifetime) SOA_A1 and SOA_NA is included, and therefore I think it should be also included in dryoa and wetoa.

Could you check whether I see this right.

[oyvindseland]

@DirkOlivie

Yes you are right. the secondary organic aerosols should also be included.

[YanchunHe]

OK, so then,
the dryoa is:
OM_ACDDF + OM_AIDDF + OM_NIDDF +OM_AC_OCWDDF + OM_AI_OCWDDF + OM_NI_OCWDDF + SOA_A1 + SOA_NA ;

and the wetoa is:
OM_ACSFWET+OM_AISFWET+OM_NISFWET+OM_AC_OCWSFWET+OM_AI_OCWSFWET+OM_NI_OCWSFWET+SOA_A1 + SOA_NA

??

Could you also go through the whole CMIP6_AERmon table variables, to check if others are correct (except for those dry dust, wetdust, dryss, dryoa, which has been corrected by not committed).

See the current list of supported variables of AERmon in https://github.com/NorESMhub/noresm2cmor/blob/master/namelists/var_CMIP6_NorESM2_default.nml

Not there are some duplicated entries of the same CMIP6 variable names, for example, dryso4. The last will override if both exist. Please let me know if you are sure that one of such option can be removed fro the var_*.nml file.

@YanchunHe

dryoa should be :
OM_ACDDF + OM_AIDDF + OM_NIDDF +OM_AC_OCWDDF + OM_AI_OCWDDF + OM_NI_OCWDDF + SOA_A1DDF + SOA_NADDF + SOA_A1_OCWDDF + SOA_NA_OCWDDF

wetoa should be :
OM_ACSFWET+OM_AISFWET+OM_NISFWET+OM_AC_OCWSFWET+OM_AI_OCWSFWET+OM_NI_OCWSFWET + SOA_A1SFWET + SOA_NASFWET + SOA_A1_OCWSFWET + SOA_NA_OCWSFWET

I'll try to have a look at the other variables too.

@YanchunHe @oyvindseland

Another issue is that in all the cmorized wet-deposition fields for aerosols (wetoa, wetso4, wetbc, wetss, wetdst) the values are negative, whereas they are positive for the dry deposition fields.
This is because the raw aerosol wet-depostion fields are negative in NorESM.
Maybe we should also correct that.

Thanks! So we need to make all of those above aerosols positive sign? (absolute values)

And also please review other AERmon fields, so that I can proceed, and republish them together with other fixes.

We would better do this at once.

Hi @YanchunHe ,

shall I change the table
https://docs.google.com/spreadsheets/d/1-XOmrpOewOJ4msZ2cuQ41NRiMKgMZ5BfiNeAAFUsp3M/edit#gid=251590531
with the following modifications :

• the sign for the five aerosol deposition fields (wetoa, wetso4, wetbc, wetss, wetdst)
• adding the contribution from SOA deposition to OA deposition (affects wetoa and dryoa)

[YanchunHe]

Yes, please do that! @DirkOlivie Thanks!
If there is not other changes for the AERmon variables, I will proceed with the cmorization and publishing.

[DirkOlivie]

@YanchunHe
I have now updated in the table the description of

• wetoa, wetso4, wetbc, wetss, wetdst
• dryoa

[YanchunHe]

@DirkOlivie

These mentioned data are processed under /projects/NS9034K/CMIP6/.cmorout/NorESM2-LM/historical/v20210319,

Could you have a look if they looks OK?

I also attached some global-averaged time series plots of these fields:

• CMIP.NCC.NorESM2-LM.historical.r1i1p1f1.AERmon.wetoa.gn.v20210319
  

• CMIP.NCC.NorESM2-LM.historical.r1i1p1f1.AERmon.wetbc.gn.v20210319

@monsieuralok

Could you retract all dryss and dryoa and wetoa variables of AERmon table for all experiments. Thanks!

I will recmorize some of them and republish.

[MichaelSchulzMETNO]

@YanchunHe
Havent you recalculated all these: wetoa, wetso4, wetbc, wetss, wetdust, dryoa
Shouldnt all these from all experiments be recomputed, retracted and republished then?

[MichaelSchulzMETNO]

By the way, I had checked the new wetoa and dryoa , compared to Gliss et al 2020 paper, and they seemed to be correct now.

[YanchunHe]

Havent you recalculated all these: wetoa, wetso4, wetbc, wetss, wetdust, dryoa

Yes, I am doing this right now, and will be ready to be republished the next week.

@YanchunHe
I have checked the wetss, wetdust, wetso4, wetbc, wetoa and dryoa and they seem ok.
