Where is the best place to address the complexity of CMIP5 experiments?
Experiment names or the r i p indices.
I noticed that the list of experiments for CMIP5 in the questionnaire is quite long and not as consistent as it might be with what we specify in the appendices of:
Here are some things to consider:
1. There should be no need for an I or E prefix on any of the runs.
2. I don't think you need separate entries for 1.1, 1.2, and 1.5 decadal expts.
3. I would omit for now the 1.6 decadalChemistry simulation since it is just a place-holder.
4. What is 3.1-S piControl? I don't think this belongs.
5. There should be no need for the "L"-prefixed rcp runs.
6. there should be no need for 6.1S 1pctCo2
7. The variously forced historical runs are now being considered part of a family (see the DRS document)
I think it would be clearer if the user would initially only see the list of experiment names shown in Appendix 1 of the DRS document. Sometimes these represent a set of closely-related experiments that are distinguished by different "rip" values in the DRS ensemble designation. In the case of the decadal runs, the initialization year may differ across the family. After selecting the the experiment family name, the user should be asked to input the "rip" value for the simulation. Much of the information entered for a family applies across the family. The user would only have to alter:
1. if the "r" value differs from previously entered simulations, information about the initial conditions and possibly the length of the run. (Note this remove the need for E- and S-prefixed runs, I think.)
2. if the "i" value differs from previously entered simulations, information about the initialization method would be asked for.
3. if the "p" value differs from previously entered simulations, information about the model physics and/or model forcing would be asked for.
In the case of decadal runs, the user would be asked to enter the initialization year before moving to the "rip" question page.
I don't think information about the length of simulations should appear in the experiment name. This is a independent piece of information that should be recorded elsewhere. Invariably an E-prefix run is the same experiment just carried out for a longer period of time. Note that different control simulations will run for different lengths of time, but we don't distinguish among these by including time information in the experiment name.
I hope you find these comments useful.
