The common Integrated Assessment Model (IAM) documentation

Integrated assessment modeling

Integrated assessment models (IAM) aim to provide policy-relevant insights into global environmental change and sustainable development issues by providing a quantitative description of key processes in the human and earth systems and their interactions. The modelling is integrated, i.e. it uses information from many scientific disciplines and describes both the human and earth system. The term assessment refers to focus on generating useful information for decision-making, even in case of large uncertainties. IAMs, for instance, have been successfully applied in support of climate policy (insights in future greenhouse gas emissions and options for mitigation), in several environmental assessments (e.g. the Millennium Ecosystem Assessment), but IAMs have also published a large amount of scientific papers.

For a nice visualization of how IAMs are used, see these (IAM infographics) as developed in the (SENSES project).

IAM Consortium (IAMC)

The IAMC wiki derives its name from and closely collaborates with the Integrated Assessment Modelling Consortium (IAMC, https://www.iamconsortium.org/). This is an organization of scientific research institutions that are involved in integrated assessment modeling and analysis. The IAMC has members from all over the world, who manage most of the IAM models that currently being used. The IAMC wiki provides a platform for these models' documentation.

Documentation

For the purpose of IAMs, a transparent model documentation is essential. IAM teams have documented their models individually, often using web-supported tools. As IAMs, however, are often used together it is also important to have information on the similarities and differences across IAM models. This database provides an overview of the IAM models using a transparent wiki-based approach that has been used consistently across a range of models. This allows for direct comparison of these models. In addition to the harmonized model documentation, also Model comparison allow for direct comparisons.

Participating models

The extent of documentation of the participating models may vary. The model documentation consists of:

• a set of documentation pages ordered in a hierarchical tree and a reference card which summarizes the main features (participation mode = full)
• a reference card only (participation mode = reference card only)

The table below shows all models that are currently "fully published" on the wiki (i.e. with complete and reviewed documentation). Models that are currently "in preparation" or "under review" are not yet shown. Note that the reference card menu in the left sidebar includes more models than in the table below. Although the reference cards are published, models do not always appear in the table, when the model documentation pages are not yet published.

Acknowledgement

The first version of the wiki benefited from the work of an earlier version developed at University College London. Major developments of this wiki-based multi-model documentation received input from the FP7 ADVANCE project (grant agreement No. 308329). Maintenance of the wiki has also been partially funded through the European Union's Horizon 2020 research and innovation programme under grant agreements No. 821471 (ENGAGE) and No. 821124 (NAVIGATE) and is being further updated and developed in the H2020 projects ELEVATE and PRISMA. The wiki has also been improved based on comments and suggestions of other modelling teams part of the IAMC. Integrated Assessment Model teams interested in joining this common documentation platform should send a mail to IAMC@pbl.nl. Please also CC your email to Rik.VanHeerden@pbl.nl.

Other forms of common model evaluation

IAM models also collaborate in other ways in order to enhance the transparency of IAM model output. First of all, various databases, such as the RCP, SSP and IPCC Report databases, host the output of several IAMs in a common format (RCP Database, SSP database, IPCC AR6 database). These databases also include key input variables to the models (please find links to key input variables on the AR6 database under 'model inputs' in the left sidebar). Second, IAM models have also produced common evaluation metrics, distilled from common simple model experiments (Kriegler2015Harmsen2021). {{#scite: |bibtex= @article{Kriegler2015, title = "Diagnostic indicators for integrated assessment models of climate policy ", journal = "Technological Forecasting and Social Change ", volume = "90, Part A", number = "", pages = "45 - 61", year = "2015", note = "", issn = "0040-1625", doi = "10.1016/j.techfore.2013.09.020", url = "http://www.sciencedirect.com/science/article/pii/S0040162513002576", author = "Elmar Kriegler and Nils Petermann and Volker Krey and Valeria Jana Schwanitz and Gunnar Luderer and Shuichi Ashina and Valentina Bosetti and Jiyong Eom and Alban Kitous and Aurélie Méjean and Leonidas Paroussos and Fuminori Sano and Hal Turton and Charlie Wilson and Detlef P.
