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.
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.
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.

The development 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). The current version benefited from the work of an earlier version developed at University College London. 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 and SSP databases, host the output of several IAMs in a common format (RCP Database (version 2.0)). Second, IAM models have also produced common evaluation metrics, distilled from common simple model experiments (12).
