pyam: analysis & visualization
of integrated-assessment and macro-energy scenarios
Overview and scope
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.
The comprehensive documentation is hosted on Read the Docs!
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
Timeseries types & data formats
Yearly data
The pyam package was initially developed to work with the IAMC template,
a timeseries format for yearly data developed and used by the
Integrated Assessment Modeling Consortium (IAMC).
model | scenario | region | variable | unit | 2005 | 2010 | 2015 |

Subannual time resolution
The package also supports timeseries data with a sub-annual time resolution:
- Continuous-time data using the Python datetime format
- "Representative timeslices" (e.g., "winter-night", "summer-day")
using the pyam extra-columns feature
Read the docs
for more information about the pyam data model
or look at the data-table tutorial
to see how to cast from a variety of timeseries formats to a pyam.IamDataFrame.
