| Summary: | 0.5° grid of fractions of grid cell that is part of one of 10 world regions as defined by IPCC Working Group 3. The "region" variable is a dimension (11, 360, 720) variable. The first axis is the fraction (0-1 scale) of the grid cell at latitude and longitude (defined by second and third axis) falling into each world region. Values of first axis correspond to following regions: 0=South-East Asia and developing Pacific 1=Eurasia 2=Asia-Pacific 3=Africa 4=Middle East 5=Latin America and Caribbean 6=North America 7=Eastern Asia 8=Southern Asia 9=Europe 10=World (all land, excluding Antarctica, and the sum of fractions in 0-9). Oceans and inland lakes are not counted within countries/regions. The starting point for this data is the 0.5° country mask from Perrette (2023). Country definitions follow the prescription of IPCC Working Group 3 Annex II (Al Khourdajie et al. 2022) where possible. Some ambiguities exist with regards to post-colonial, geographically detached, and disputed territories which are not explicitly defined in Annex II. These have been grouped by geographic rather than political region (example: French Guiana is classified as Latin America & Caribbean, which it is most definitely geographically part of, rather than Europe, which it is politically part of). A more detailed list of region mappings is available from WG3 authors which is mostly consistent with Annex II and has been followed. Two changes have been made to this list for consistency with Annex II: North Macedonia has been placed in Europe (rather than Eurasia) and Ukraine has been placed in Eurasia (rather than Europe).
