:wave: @sadielbartholomew, @ashiklom, @znicholls this is the review thread for the paper. All of our communications will happen here from now on.

Both reviewers have checklists at the top of this thread with the JOSS requirements. As you go over the submission, please check any items that you feel have been satisfied. There are also links to the JOSS reviewer guidelines.

The JOSS review is different from most other journals. Our goal is to work with the authors to help them meet our criteria instead of merely passing judgment on the submission. As such, the reviewers are encouraged to submit issues and pull requests on the software repository. When doing so, please mention openjournals/joss-reviews#2766 so that a link is created to this thread (and I can keep an eye on what is happening). Please also feel free to comment and ask questions on this thread. In my experience, it is better to post comments/questions/suggestions as you come across them instead of waiting until you've reviewed the entire package.

We aim for reviews to be completed within about 4 weeks. Please let me know if any of you require some more time. We can also use @whedon (our bot) to set automatic reminders if you know you'll be away for a known period of time.

Please feel free to ping me here (@leouieda) or email me privately if you have any questions/concerns.

@ashiklom thank you for your thorough review (and issues on the software repository)!

@znicholls please do you best to address some of the points raised, in particular:

  1. Adding suggested context to the statement of need. Including it in the docs is a good idea and helps define the scope of the project.
  2. Fleshing out the "State of the field" in the JOSS paper.

Please keep us posted on your progress 🙂

  • For instance, were previous implementation of the two-layer model in something less user-friendly like Fortran or less open like Matlab?

On this one I'm not sure. There's FaIR, but it is missing some of the conversion functionality and modularisation we've implemented here (as mentioned in the draft). I haven't been able to find any other public implementations so couldn't comment on other languages unfortunately.

znicholls commented 4 years ago

@ashiklom I've added a table with openly accessible models from RCMIP (so just FaIR, GREB and Hector) to openscm/openscm-twolayermodel#25. Does that work or would extra text and explanation be useful?

Are there any openly available implementations? Maybe highlight that more, if that's the case?

Not as far as I'm aware.

Maybe one could reference models that are easily driven in forcing mode? Oscar, WASP and Pymagicc/MAGICC are also openly available on GitHub, but then one slowly ends up referencing the entire table from the RCMIP paper ...

ashiklom commented 4 years ago

I think the table you added combined with the references to the RCMIP paper throughout the documentation are sufficient to address this (you might consider making it extra clear that the RCMIP paper is the more comprehensive list -- e.g., "For a more extensive list of simple climate models, see Nicholls et al... (link)".

znicholls commented 4 years ago

Oscar, WASP and Pymagicc/MAGICC

I've added these now

Maybe one could reference models that are easily driven in forcing mode?

I could do this, that would mean I'd remove GREB. Seems fine to me as it's also kind of outside the typical idea of a simple climate model.

There is probably no clear distinction, so i'd keep it. As it's also meant for teaching (i think) it would be a good pointer!

Hi, I can start my review in earnest shortly, so can I just check that the state of the repository and of the paper has stabilised now in terms of changes made resulting from feedback from the first review, @znicholls ?

It's been a few days since any activity (at least as indicated on this thread) so it seems likely, but think it best to check to avoid starting the review and have some change go in that might influence the judgement I can make.

znicholls commented 4 years ago

Yep I've just merged everything into master and will get whedon to recompile now. Thanks for checking and reviewing!

:wave: Hi @sadielbartholomew, @ashiklom just checking in to see how this is going. It's been a while since there was any activity here.

@ashiklom I noticed that your checklist is nearly finished. Could you please go over once more and see if the recent changes meet all of the requirements?

sadielbartholomew commented 3 years ago

Hi @leouieda, thanks for checking in. Sorry for the delay, which has arisen because I've been prioritising another JOSS review which began at an earlier date that this one. But I have largely completed that now, so I can focus on this review. I'll aim to complete it by the end of the week. Thanks to all for your patience.

ashiklom commented 3 years ago

Yes, recent changes look good -- thanks! My checklist is now complete.

leouieda commented 3 years ago

@ashiklom thank you for the review 👍🏽

@sadielbartholomew I appreciate all your hard work for JOSS 🙂 Let me know if you need more time or have any questions/concerns.

sadielbartholomew commented 3 years ago

Hi @leouieda @znicholls, I started my review however before proceeding with the remainder I feel obliged to request a more experienced opinion regarding the 'substantial scholarly effort' criterion because, while it is clear more than sufficient academic effort has been conducted related to the context of this package, I am not convinced the package itself meets the minimum threshold of three months work so, as per the JOSS review guidelines, I need to flag this so an informed decision can be made by the editors in this respect.

I say this tentatively, because it is difficult to grasp the effort put into a package. I am aware the model is simple by design and the fact it has been used and cited in the RCMIP paper indicate it is important to the research area and indeed very citable. My concerns stem largely from the line counts of the functional Python code, excluding tests and configuration scripts which seems to be ~1500 lines:

$ pwd
/home/sadie/openscm-twolayermodel/src/openscm_twolayermodel
$ find . -name '*.py' | xargs wc -l
  314 ./base.py
   12 ./__init__.py
   15 ./errors.py
   10 ./constants.py
  321 ./impulse_response_model.py
  520 ./_version.py
  355 ./two_layer_model.py
   37 ./utils.py
 1584 total

which is low enough to plausibly have taken less than three months in total considering even the related research time for the idea, design, implementation planning and incremental changes, etc. The commit history indicates it has been worked on at least on GitHub for about two-thirds of a year, but the total work time can't be inferred from that.

@leouieda please can you provide the editorial opinion on whether I can consider this criterion met. If so I will be very happy to proceed with the remainder of the review.Thanks.

znicholls commented 3 years ago

For context the comments in the pre-review:

leouieda commented 3 years ago

@sadielbartholomew thank you for bringing this up. As @znicholls pointed out, we had discussed this in the prereview since the line count is on the small side. However, I'm not a climate researcher which is why we decided to get the opinion of reviewers as well. As you mentioned, this is evidently a useful piece of software given that it's already been cited. From my side, I would be happy to treat this as in scope if you agree. The "three months of effort" is more of a rule of thumb than a hard requirement. But as I said, I'm not an expert in this field. Please also consider the amount of effort that went into testing and documentation.

So disregarding the "3-month of effort" concept, do you think this qualifies as a "substantial scholarly effort"?

ashiklom commented 3 years ago

My 2 cents: I think this is comfortably within scope. We as an Earth science community need more user-friendly modeling tools like this, and more citable papers describing those tools.

rgieseke commented 3 years ago

I'm obiously biased (as i'm part of the OpenSCM projects) but this tool is also using the scmdata and openscm-units projects by the same authors which help making the code in this project look succinct by moving boilerplate code to re-usable modules..

sadielbartholomew commented 3 years ago

Thanks all for the comments RE the 'substantial scholarly effort' criterion.

However, I'm not a climate researcher which is why we decided to get the opinion of reviewers as well.

I work as an effective research software engineer in the field of climate research, however that's quite different to being a climate researcher, and I am definitely not an "expert" in the field either! So that's an important caveat to note. If you require the opinion of someone who fits that kind of description, I do have numerous colleagues who would fit that description, some of whom I might be able to seek the opinion of (should that be permitted relating to COI rules).

However, if my own opinion is sufficient, based on the comments here, in particular that our first reviewer @ashiklom regards it as "comfortably within scope", that my answer to the following is 'yes, absolutely':

So disregarding the "3-month of effort" concept, do you think this qualifies as a "substantial scholarly effort"?

and the good point by @rgieseke that:

this tool is also using the scmdata and openscm-units projects by the same authors which help making the code in this project look succinct by moving boilerplate code to re-usable modules

where fewer lines of code is a mark of quality in my eyes, I am more than happy to consider OpenSCM Two Layer Model as being 'substantial scholarly effort'.

Are we okay to take my own judgement (given the above caveat) @leouieda? (If so, I will tick that item and I will finish my review soon.) If not, would it help for me to check in with a colleague that is an experienced climate researcher (who can self-certify as having no COI) for their view?

As a side note, I do generally agree with the sentiments such as:

We as an Earth science community need more user-friendly modeling tools like this, and more citable papers describing those tools.

but I am trying to be as objective as possible and judge purely on the review criteria.

leouieda commented 3 years ago

@sadielbartholomew thank you for being so thorough and trying to look at this from a different perspective. I'm happy to take your own judgement on this since @ashiklom agrees. Please let me know when you're done and all checks have been marked in the review issue.

@znicholls thank you for your patience since this review has taken longer than usual, in no small part because of me. After reviews are done, there are some editorial procedures to go through but they should be fairly quick.

Happy New Year to everyone! 🍾

sadielbartholomew commented 3 years ago

Thanks @leouieda in that case I will proceed ASAP and shall aim to finish the review by the end of this week.

sadielbartholomew commented 3 years ago

I'll have this completed and report back in the next few days, thanks all for your patience.

znicholls commented 3 years ago

Hi all, no real rush from my side but just checking in to see if there is any timeline for resolving this?

sadielbartholomew commented 3 years ago

Hi, I am really sorry @znicholls I was ill after my previous comment and then this fell off my radar when I was back catching up on things.

I'll resume my review later today and finish it, reporting back on this thread with any feedback, sometime this weekend and certainly by the end of the weekend in UTC time. My apologies and thanks for your patience.

znicholls commented 3 years ago

Hi @sadielbartholomew, thanks for the update and please look after your health first. There isn't a rush on this just good to know it hasn't disappeared completely.

sadielbartholomew commented 3 years ago

Summary of review

I am very satisfied with both the software and the paper, notably that they meet the requirements. Therefore I have now ticked all review list checkboxes and I am happy to recommend acceptance of the OpenSCM Two Layer Model paper for publication.

Please do consider the minor comments I raise below @znicholls, though they are merely suggestions or questions that came to me during review and whether or not any changes are made in response to them is up to you, it does not influence my decision to suggest approving the paper to @leouieda.

The most important of these comments are probably those regarding the documentation of, and output of, the the automated tests (I'm about to open some minor PRs regarding these items).

Thanks to all for awaiting my review.

Note: for impartiality I have not re-read through the comments of the first reviewer before my review, and hence not referenced them here. Therefore I may have covered points that have already been raised. If they have been addressed satisfactorily already, there is no need for further action.

Minor comments

Organised in correspondence to the review checklist (no mention of a given check box item means I don't have any comments to make about it, other than that I am satisfied it is met by the software and/or paper):
