Metis provides a framework allowing analysis of dynamics across multiple sectors including energy, water, land and socio-economics at variable spatial and temporal scales. It is designed to be a flexible tool which can take inputs from both global integrated assessment models (IAMs) which capture global dynamics as well as more detailed models which capture specific sub-regional and sectoral details at finer resolutions. Metis integrates across tools by sharing data in standardized formats. In most projects looking at multi-sector dynamics one of the key constraints is data availability and a key goal of Metis is to overcome this barrier by providing users with default data across sectors for their specific region. The default data is built from outputs of the open-source Global Change Assessment Model (GCAM) eco-system which provides downscaled gridded global data for water, energy and land. Metis aggregates gridded data to any spatial boundary and offers users a first look at the water-energy-land situation in their regions of interest. The idea is to use this as a starting point and then improve the data as and when it becomes available while working with local stakeholders. After aggregating data to relevant spatial and temporal scales, Metis finds relationships between the sectors using input/output methods to establish correlation matrices. The correlation matrices represent the inter-sectoral links throughout the system and are used to investigate impacts of changes in demands, efficiencies and capacity in one sector on others.
