message_ix_models.project.ssp

Shared Socioeconomic Pathways (.project.ssp)

Structure

The enumerations SSP_2017 and SSP_2024 contain one member from the corresponding SDMX code lists. These can be used to uniquely identify both an SSP narrative and the set in which it occurs, in applications where this distinction is meaningful:

>>> from message_ix_models.project.ssp import SSP_2017, SSP_2024
>>> x = SSP_2017["2"]
>>> y = SSP_2024["2"]
>>> str(y)
"ICONICS:SSP(2024).2"
>>> x == y
False

Data

message_ix_models.project.ssp.data

Although free of charge, neither the 2017 or 2024 SSP data can be downloaded automatically. Both sources require that users first submit personal information to register before being able to retrieve the data. message_ix_models does not circumvent this requirement. Thus:

  • A copy of the data are stored in message_data.
  • message_ix_models contains only a ‘fuzzed’ version of the data (same structure, random values) for testing purposes.

Allow users without access to message_data to read a local copy of this data from a .Config.local_data subdirectory.
