Thanks @huard for raising this important topic!
pyam
used for recent IPCC reportsFor completeness, let me first point to how we handled this in recent work related to IPCC reports.
For the IPCC SR15, the open-source Jupyter notebooks (using pyam
) to create a number of figures, tables and statements in the report are available in rendered format and on GitHub.
(doi: 10.22022/SR15/08-2018.15428)
The data used in these notebooks is available via the IAMC 1.5°C Scenario Explorer, with references to the underlying manuscripts on the About page and via individual data panels. (doi: 10.22022/SR15/08-2018.15429)
For the recently published IPCC SRCCL, @kvcalin used pyam
for some of her scenario assessment with an updated version of the same data. She may still publish a suite of notebooks for reproducibility and transparency (time permitting, I guess).
Comment: If such notebooks could be published in parallel and cross-referenced in future reports, that would be a (admittedly low-key, unsophisticated, unstructured) way to increase transparency and show provenance information.
pyam
A pyam.IamDataFrame
consists of a data
table containing timeseries information and a meta
table containing qualitative and quantitative indicators. One could see the "source" of a scenario as a meta-indicator, using df.set_meta() to mark a certain set of scenarios as originating from a particular manuscript or project. See cells 61-64 in this notebook for a rather clumsy way of using this feature to map scenarios to source manuscripts for the SR15 assessment.
Adding an RDF to pyam
for tracking entities, agents and activities on an IamDataFrame
and embedding it in resulting figures would be feasible in principle (using the Python package prov, for example), but I don't see the resources to implement this in a realistic timeframe. Publishing notebooks together with a graph/figure or table seems, to me, like the more realistic way forward for the time being.
Thanks @danielhuppmann for the detailed answer and your view on what is realistically achievable.
Hi all - FWIW, we employ semantic versioning, continuous integration, and deploy installable packages via pip and conda. As this is a two to three person operation at the moment without any funding mechanism, I do not suspect we will go further without additional resources.

There is a push in the IPCC to track provenance information for the figures and tables it publishes in its assessment reports. In WGI, ESMValTool and Climate4R have implemented provenance tracking mechanisms around the PROV standard (Climate4R has defined an extension to the stock ontology called metaclip, see metaclip.org for an example). I was wondering if pyam developers had considered similar mechanisms?
