Three user interface modes enable interactive analyses at different levels of complexity

GAINS Basics mode
It allows rapid exploration of the key features of (pre-defined) alternative policy intervention scenarios.

GAINS Advanced mode
This mode provides all technical details of activity projections and policy response scenarios with a more complex user interface.

GAINS Expert mode

This mode enables upload of own activity projections, specifying new policy packages, and comprehensive cost-effectiveness and cost-benefit optimization analyses. As this version is still under development and requires substantial training, access is only granted to IIASA collaborators.
