Abstract

This dataset provides country scenarios, downscaled from the RCP (Representative Concentration Pathways) and SSP (Shared Socio-Economic Pathways) scenario databases, using results from the SSP GDP (Gross Domestic Product) country model results as drivers for the downscaling process harmonized to and combined with up to date historical data.

Files included in the dataset

The repository comprises several datasets. Each dataset comes in a csv file. The file name is constructed from dataset properties as follows: <Source><Bunkers><Downscaling>.csv

<Source>

The "Source" flag indicates which input scenarios were used.

  • PMRCP: RCP scenarios downscaled using the SSPs: emissions and socio-economic data; scenarios are available both harmonized to historical data and non-harmonized.
  • PMSSP: Downscaled SSP IAM scenarios: emissions and socio-economic data; scenarios are available both harmonized to historical data and non-harmonized.

<Bunkers>

the "Bunkers" flag indicates if the input emissions scenarios have been corrected for emissions from international shipping and aviation (bunkers) before downscaling to country level or not. The flag is "B" for scenarios where emissions from bunkers have been removed before downscaling and "" (no flag) where they have not been removed.

<Downscaling>

The "Downscaling" flag indicates the downscaling technique used.

  • IE: Convergence downscaling with exponential convergence of emissions intensities and convergence before transition to negative emissions.
  • IC: Regional emission intensity growth rates for all countries.
  • CS: Constant emission shares as a reference case independent of the socio-economic scenario.

All files contain data for all countries and variables. For detailed methodology descriptions we refer to the paper this dataset is a supplement to. A reference to the paper will be added as soon as it is published.

Finally the data description including detailed references is included: RCP-SSP-dwn_v1.0_data_description.pdf.

Notes

If you encounter problems with the size of the csv files please let us know, so we can find solutions for future releases of the data.

Data format description (columns)

"source"

For PMRCP files source values are

  • RCPSSP<Bunkers><Downscaling>: unharmonized downscaled RCP SSP scenarios
  • PMRCP<Bunkers><Downscaling>: downscaled RCP SSP scenarios harmonized to and combined with historical data
  • PMRCPMISC<Bunkers><Downscaling>: GDP and population data harmonized to and combined with historical data

For PMSSP files source values are

  • SSPIAM<Bunkers><Downscaling>: unharmonized downscaled SSP IAM scenarios
  • PMSSP<Bunkers><Downscaling>: downscaled SSP IAM scenarios harmonized to and combined with historical data
  • PMSSPMISC<Bunkers><Downscaling>: GDP and population data harmonized to and combined with historical data

For possible values of <Bunkers> and <Downscaling> please see section Files included in the dataset above.

"scenario"

For PMRCP files the scenarios have the format <RCP><SSP><group>, where

  • <RCP> denotes the RCP scenario. Values are RCP3PD, RCP45, RCP6, and RCP85.
  • <SSP> denotes the SSP scenario. Values are SSP1, SSP2, SSP3, SSP4, and SSP5.
  • <groups> denotes the SSP basic elements GDP modeling group. Values are IIASA, OECD, and PIK. Not all RCP SSP combinations exist as some SSP storylines are not compatible with all RCP emissions scenarios. For details we refer to the paper this dataset is a supplement to. A reference to the paper will be added as soon as it is published.

For PMSSP files the scenarios have the format <SSP><forcing><model> where

  • <SSP> denotes the SSP scenario. Values are SSP1, SSP2, SSP3, SSP4, and SSP5.
  • <forcing> denotes the radiative forcing level of the scenario. Values are 19, 26, 34, 45, 60, 85, and BL where 19 stands for 1.9W/m2 etc. and BL stands for baseline.
  • <model> denotes the Integrated Assessment Model (IAM) used to generate the scenario. Values can be found below
