MAgPIE 4.8.1

[4.8.1] - 2024-06-19

notes

• for running MAgPIE without POP/GDP update, change all instances of rev4.109 to rev4.107 in these two files: config/default.cfg and config/scenario_config.csv
• rev4.108 should not be used anymore because MER-GDP was wrong and was identical to PPP-GDP

changed

• 29_ageclass module 29_ageclass has been renamed to 28_ageclass to make space for 29_cropland just before 30_croparea
• 30_crop module 30_crop renamed to 30_croparea, which now only accounts for crop area.
• 30_crop Semi-Natural Vegetation (SNV) implementation has been moved from 30_crop to 29_cropland
• 30_crop the previous 30_crop/endo_apr21 realization has been moved to 30_croparea/simple_apr24
• 30_crop the two realizations penalty_apr22 and rotation_apr22 have been merged into a single 30_croparea/detail_apr24 realization
• default.cfg update additional data to rev4.51
• scripts adjusted SLURM job handling
• scripts updated EL2p0 start scripts

added

• 10_land added interface pm_land_hist with historic land use patterns

removed

• 32_forestry removed technical balance term v32_land_missing_ndc

• 35_natveg avoid infeasibilities due to very small numbers
• 44_biodiversity Fixing to SSP2 parameters until 2025 was not working
