Article Title: A global CORDEX-based dataset delineating urban areas and their surroundings to assess climate change in megacities

Figure Lengend Snippet: Heatmap showing the number of urban and rural grid cells, as well as their actual ratio of rural to urban grid cells (the target is 2), derived from the REMO and RegCM models, as well as from GHS-UCDB-based dataset. The analysis includes both the CORDEX-CORE (0.22°) and CORDEX-EUR-11 (0.11°) domains. City names are accompanied by their corresponding domain and resolution for reference. A value of zero for urban cells indicates that no grid cell exceeded the urban fraction threshold defined for that model, and therefore, no urban area was detected at this resolution. In contrast, missing values (i.e., empty cells) indicate that urban fraction data are not available for that specific model-domain combination.

Figure Lengend Snippet: Urban/rural areas for the city of London using the REMO model from CORDEX-EUR-11. Shaded colors represent the values of the variable ‘urmask’, where 1 (yellow cells) indicates grid cells classified as urban, 0 (purple cells) corresponds to rural cells, and NaN denotes areas not classified as either urban or rural. On the right, the dimensions, coordinates, and attributes of the “urmask” variable are displayed.

Figure Lengend Snippet: Minimum temperature anomaly maps (relative to the mean rural minimum temperature) for London, based on RegCM and REMO model simulations over the CORDEX-EUR-11 domain. The first column presents spatial maps, where solid brown and green lines represent urban and rural areas, respectively. The pink polygon indicates the city extent as defined by the GHS-UCDB dataset. The second column shows the monthly annual cycle for urban (brown) and rural (green) areas. Each line corresponds to an individual urban or rural grid cell, while thicker lines represent the median across all urban or rural cells. The evaluation period is 1979–2014.
