Urban Heat: Forward-Looking Climate Modelling for West-Africa : Corridor Abidjan-Lagos

We produced actionable data on heat stress in cities to inform analysis and client dialogue on the part of World Bank teams. We applied an urban-scale climate modeling framework to generate datasets describing modeled heat stress exposure for present-day and future conditions under selected climate scenarios. The study focuses on five cities at Corridor Abidjan-Lagos: Abidjan, Cotonou, Lome, Accra and Lagos.

More details about the dataset: 

The dataset includes calculations for each indicator for the reference period (present: 2001 to 2020). For city Lome two more future scenarios (SSP2-4.5, SSP3-7.0) and with two twenty-year periods (2031-2050, and 2051-2070) were applied.

All indicators are available in both NetCDF and GeoTiff formats.

The indicators are calculated at a resolution of 100 m to 200 m (depending on the size of the city), consistent with the UrbClim and WBGT simulations. Additionally, downscaled versions of the indicators are provided at a resolution of 30 m.

The UrbClim and WBGT simulations, as well as the postprocessing, are conducted using the regional projection. The NetCDF and GeoTiff data also adopt this projection. Furthermore, a GeoTiff data file with EPSG 4326 projection is included.

All indicators are calculated as yearly averages.

The indicators in NetCDF and GeoTiff format as well as the visualized PNG files can be found in the {city}_present_indicators.zip or {city}_indicators.zip (for Lome).

Three representative locations within the study domain have been selected to retrieve the WBGT profile on a chosen date (a hot day in 2020). The results are stored in WBGT_data.xlsx and visualized as WBGT_{date}.png. The shapefile is named as selected_locations.shp. These data together with the visualization of the land use map is compressed in {city}_landuse_wbgt.zip.
