This dataset contains the inputs used for validation of six global flood models (GFMs) against observed events in Nigeria and Mozambique. The dataset includes shapefiles that contain the analysis areas for the three study regions of Lokoja, Idah, and Chemba. For each study region, the observed flooding (obtained from the Dartmouth Flood Observatory) is included in GeoTIFF raster format at a resolution of 1/1200 decimal degrees (~90m). For each study region, the modelled flood extent from 6 GFMs is included in GeoTIFF raster format, resampled to a resolution of 1/1200 decimal degrees (~90m). Individual GFM output is provided in return periods of 25 and 100 years. The GFMs included are: CaMa-Flood, GLOFRIS, ECMWF, JRC, SSBN, and CIMA-UNEP. Finally, for each study region, the 25 year return period aggregated flood model (an output from the Global Flood Model Intercomparison Project) is included in GeoTIFF raster format at a resolution of 1/1200 decimal degrees (~90m). Each file is in the WGS84 projection.

The file formats can be read by any Geographical Information System Software (GIS)
