The IIASA Modeling Platform Server

The IIASA Energy, Climate, and Environment Program (ECE) hosts a suite of Scenario Explorer instances and related infrastructure to support analysis of integrated-assessment pathways in IPCC reports and model comparison projects. High-profile use cases include the IAMC 1.5°C Scenario Explorer hosted by IIASA supporting the IPCC Special Report on Global Warming of 1.5°C (SR15) and the Horizon 2020 project CD-LINKS.

This page provides the technical documentation for the database infrastructure. For more information on the hosted instances and related projects, please visit

The server infrastructure is built on the open-source integrated and cross-cutting modelling platform package (ixmp). The platform provides a data warehouse for high-powered numerical scenario analysis. It allows an efficient workflow between original input data sources and implementations of mathematical models, via application programming interfaces (API) with the scientific programming languages Python and R as well as a REST API for access via web-based applications.
