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.
  • 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.)
  • Adjust efficiencies of LDV PHEV technologies using duty cycle data.
  • 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:
  • Handle missing countries in IEA EWEB data #230

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

How to review

TBA

PR checklist

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