The open-source Python package pyam provides a suite of tools and functions for analyzing and visualizing input data (i.e., assumptions/parametrization) and results (model output) of integrated-assessment models, macro-energy scenarios, energy systems analysis, and sectoral studies.

Key features

Simple analysis of scenario timeseries data with an interface similar in feel & style to the widely used pandas.DataFrame
Advanced visualization and plotting functions (see the gallery)
Scripted validation and processing of scenario data and results
