Transport improvements from 2024-W49

[khaeru]

• Items for SSP 2024/ScenarioMIP.
  • Update base scenario URLs from e.g. ixmp://ixmp-dev/SSP_dev_SSP1_v0.1_Blv0.18/baseline_prep_lu_bkp_solved_materials to e.g. ixmp://ixmp-dev/SSP_SSP1_v1.1/baseline_DEFAULT_step_13.
  • Constrain t=conm_ar (a P AIR technology) to a low/zero share in 2020. This technology was (a) taking a large share in y=2020 without constraints and (b) because not present at all in IEA EWEB for some regions, was being scaled with 1.0, so passing through as a large value.
  • [ ] Next PR: Use a smaller growth_activity_up value for (t=ICAm_ptrp, n=R12_RCPA). The technology constraint as of 2020 is effective, but this tech/region grows too rapidly to 2025 and beyond. (per discussion with @r-aneeque 2024-12-04.)
  • [ ] Next PR: Adjust efficiencies of LDV PHEV technologies using duty cycle data.
  • [ ] Next PR: Ensure growth_activity_up and act-non_ldv.csv values are set for F ROAD technologies with, at least, c=gas inputs. This is to avoid the behaviour (observed by @r-aneeque) that the model quickly switches into these in 2025–2030. Rework .transport.Config.constraint to simplify the setting of these constraints.
• Items for aviation emissions postprocessing:
  • Implement method 'B'.
  • Handle missing countries in IEA EWEB data #230

This branch is currently was temporarily triggering the message_data transport runs using iiasa/message_data#582, which limits to a subset of all scenarios.

How to review

Per aviation emissions:

• View the diff (click 'Files changed' above), particularly the file message_ix_models/data/transport/emi-intensity.csv.
• View the preview build of the documentation, in particular the page “Shared Socioeconomic Pathways (project.ssp)” and section “2024 update > transport”, here.
• Confirm the code runs without error on the files in ECE SharePoint > Documents > SharedSocioeconomicPathways2023 > Scenario_Vetting (for instance, the subdirectory v2.1_Internal_version_Dec13_2024 > Reporting_output.
• View the output and note any qualitative or quantitative issues to be resolved.

PR checklist

• Continuous integration checks all ✅
• Add or expand tests; coverage checks both ✅
• Add, expand, or update documentation.
• Update doc/whatsnew.
