IPSLCM6-AER ^{(To do list for Anne and Ramiro before launch CMIP6 simulations )}

1. Which simulations ?

Simulation Name	Tier	Domains	Duration	Properties	Info	LINK
piClim-control	1	Atm+Aer	30 years	Fixed SST ERF	PI sst, ice climatology, PI aer	​Official Description
piClim-aer	2	Atm+Aer	30 years	Fixed SST ERF	PI sst, ice climatology, PD aer	​Official Description

2. Ping files

• send email to Arnaud (2020/04/30)
• Arnaud answer

  Hi Anne and Ramiro,
  
  I have generated xmls files for piClim-control experiment (30 years from 1850 to 1879) because they are different from piControl experiment.
  Could you test them on 1year simulation (before launching 30 years) ? Let me know if it is ok for you. Once you will have confirmed it is ok, I will generate xmls files for other experiments.
  
  Cheers,
  
  Arnaud
  
  
  

Path is : IGCM/CMIP6/IPSLCM6.1.11-LR/IPSL-CM6A-LR-INCA/piClim-control

• 2020/05/01 There is a new experiment directory ​EXPERIMENTS/LMDZORINCA/piClim-control_CMIP6/ with ping files
• 2020/05/01 commit because I forget the inca ping file (!!!) see rev ​here
• 2020/05/01 commit for an error on dr2xml inca file ​here

Simulation bug with this error

 A grid must be defined for field 'CMIP6_rlutcsaf'

--> to do : understand this problem and correct it. (on next monday)
20200504 : correction done, the lmdz ping files was not the good one. New revision ​5077. Now the simulation run for 1 day, I will test a longer run (1 year) to check post-treatment

3. input files for forced model

3.a SST : mail from Olivier Boucher

Il me semble que pour être cohérent avec la non-réalisation d'un DECK, il doit prendre les SST du piControl officiel. Que dit le protocole pour ces simulations à SST fixées ? SST observées ou SST du piControl ?

translation

to be coherent with the fact we not rerun a deck, we need to use SST from the offical picontrol simulation. Before to made this choice we need to check the protocol for fixed sst ? observed or picontrol sst ? 

Ramiro

verify protocol to know if we use sst from obsevation or from picontrol run

• The protocol indicates that: Fixed SST ERF simulation. Use pre-industrial climatological average SST and sea-ice distributions.
• The official paper describing AerChemMIP indicates:

The control simulation for these experiments will use 1850concentrations of WMGHGs and emissions of NTCFs, run for 30 years in atmosphere-only mode with SSTs and sea ice prescribed as a (monthly varying) climatology taken from 30 years of the pre-industrial control (experiment piClim-control; see Table 6) following the Radiative Forcing Model Intercomparison Project (RFMIP) specification (Pincus et al., 2016).

We have then to use the piClim-control

Anne

ask Arnaud path for the official ipslcm6 picontrol simulation. --> path send by email 20200504

2020504 : Arnaud

J'ai fait les xmls pour 30 ans de 1850 à 1879 mais vous pouvez prendre une autre periode de 30 ans que celle-là si vous le souhaitez...à la fois par rapport au protocole demandé mais peut etre aussi par rapport à la periode de 30 ans du picontrol de laquelle vous voulez extraire les sst de forcage (peut etre que certains 30 ans sont "mieux" que d'autres"...)...

Translation :

I did xmls files for 30 years from 1850 to 1879, but you can use an other 30 years periods than this one if the protocol ask it, or if you prefer an other period from the picontrol simulation

3.b AER

pi / pd

Ramiro do you have files for these two inputs files ?

The links I have added to the table indicates the input needed by each simulation. piClim-control and piClim-aer. For piClim-control we need 1850 forcings, for piClim-aer the forcings are the same but aerosols emissions and precursors are from 2014.

4. Experiment directory

Add a new experiment directory for forced model : ​first commit

4.1 Questions to solve

• which ModelName in config.card ?
• which TagName in config.card ?

--> the answer to the ping files give some clues. We need to take same parameter than for coupled model
2020/05/01 : make modification in experiment directory and change name of this directory to be coherent with the type of experiment : piclim-control instead of picontrol ​see here

6. IPSLCM6-AER (Second set of simulations)

Name	Tier	Min. Config	Period	Kind	Notes
piClim-2xDust	2	Atm+Aer	30 years	Fixed SST ERF	PI-sst, PI forcing, 2x dust emission
piClim-2xSS	2	Atm+Aer	30 years	Fixed SST ERF	PI-sst, PI forcing, 2x ss emission
piClim-2xDMS	3	Atm+Aer	30 years	Fixed SST ERF	PI-sst, PI forcing, 2x DMS emission

piClim-NTCF	1	Atm+Aer	30 years	Fixed SST ERF	PI-sst, PI forcing, 2014 NTCF emission
piClim-SO2	3	Atm+Aer	30 years	Fixed SST ERF	PI-sst, PI forcing, 2014 SO2 emission
piClim-OC	3	Atm+Aer	30 years	Fixed SST ERF	PI-sst, PI forcing, 2014 OC emission

All this set of simulations needs a change in the code (for example to have x2 SS) or in the forcings (or even in both)
