REMIND-MAgPIE

  • MAgPIE
    • Update model version from v4.7.0 to v4.7.1
    • Switch to forestryExo realization to keep timber area constant
  • REMIND
    • Switch from a regional "keep net-zero CO2 emissions after peak"-target to a global one. This way we allow individual regions to still generate net negative emissions in order to compensate for emissions in other regions, as long as global net emissions do not become negative.
    • Activate global 5 Gt CO2/yr OAE bound with GDP-based regional shares.
  • Update CEDS reporting
    • Change definition of CDR from re- and afforestation. Before we assumed CDR from re- and afforestation is simply the amount of regional net negative LUC emissions. Now we explicitly use the natural regrowth in Secondary Forest, Other Land and Timber Plantations, as well as in forests that were intentionally planted to generate negative emissions, that is, via price-incentives CO2-price AR, or via specific policy targets NPI_NDC AR. This is based on the UNFCCC convention that all LUC emissions that can be attributed to “human activity” is defined as CDR.

  • gridded dataset for 2015-2100 in 10-year for 1 scenario:
    • RESCUE-Tier1-Direct-2023-12-13-PkBudg500-OAE_on

Gridding

  • The separate CO2_em_removal variables were integrated as new sectors into the CO2_em_anthro variable for all types of negative emissions: Afforestation, BECCS, DACCS, EW, Industry and OAE.
  • The gridded scenario data starts in 2015 (where 2015-2020 derives from a custom CEDS2017 extension)
  • Consistent data form:
    • Dimensions are ordered time, level or sector, lat, lon
    • Sector coordinates have guaranteed orders:
      • {gas}_em_anthro variables have: Agriculture, Energy, Industrial,Transportation, Residential, Commercial, Other, Solvents Production and Application, Waste, International Shipping
      • CO2_em_anthro variables have the same sectors, but in addition the negative emissions sectors: CDR Afforestation, CDR BECCS, CDR DACCS, CDR EW, CDR Industry, CDR OAE
      • {gas}_em_openburning has: Agricultural Waste Burning, Forest Burning, Grassland Burning, Peat Burning
    • Data type is float32
    • Time dimension is monthly in the years 2015, 2020, 2030, ..., 2100.

WARNING: Since not all proxy discussions have concluded, Afforestation, BECCS, EW and OAE are only provided as nan values in this preliminary review round.

REMIND-MAgpIE

No updates.

2023-12-08

  • dataset for 1995-2100 in 10-year timesteps for 6 scenarios.

Gridding

  • Updated filenames and netcdf metadata following the structure in CMIP6
  • New shipping proxies by MariTeam
  • New CDR proxies for DACCS and Industrial CDR
  • Fixed harmonisation and downscaling for incomplete proxies
  • Fixed F-Gas split regression
  • Fixed uniform grid (720x360)

REMIND-MAgpIE

  • Update MAgPIE model version number from v4.6.7 to v4.7.0
  • Activate timber module in MAgPIE to represent managed forests

2023-10-11

Gridding

REMIND-MAgpIE

  • Update REMIND model version
    • Update REMIND version number from v3.1.0 to v3.2.0; in particular improving near term realism within REMIND (effectively reduces remaining carbon budget)
    • Updated assumption on OAE realization, reducing emissions from limestone calcination
    • Remove overshoot scenarios with OAE, since the new assumptions lead to model instabilities
    • Deactivate climate change impacts within MAgPIE
  • Update CEDS emissions reporting
    • Fix/Improve emissions reporting to match CEDS historic emissions
    • Reallocate OAE calcination emissions to end-use sectors
