Supplementary dataset for "Potential of Wastewater Reuse to Alleviate Water Scarcity under Future Warming Scenarios"

The folder contains water gap data relative to the paper:Kahn, M., Sangiorgio, M., and Rosa, L. (2025) Potential of wastewater reuse to alleviate water scarcity under future warming scenarios. Environmental Research Letters, 20, 034012https://doi.org/10.1088/1748-9326/adb31d All water gaps data are in km3/yr. Gridded data(NetCDF at 0.5°) baseline (2001-2010) Water_gap_baseline_no_wastewater_reuse: Water gap under baseline climate scenario with no wastewater reuse. Water_gap_baseline_treated_wastewater_reuse: Water gap under baseline climate scenario with treated wastewater reuse. Water_gap_baseline_full_wastewater_reuse: Water gap under baseline climate scenario with full wastewater reuse. 1.5°C warming Water_gap_15_no_wastewater_reuse: Water gap under 1.5°C warming scenario with no wastewater reuse. Water_gap_15_treated_wastewater_reuse: Water gap under 1.5°C warming scenario with treated wastewater reuse. Water_gap_15_full_wastewater_reuse: Water gap under 1.5°C warming scenario with full wastewater reuse. 3°C warming (5 models + average) Water_gap_3_no_wastewater_reuse: Water gap under 3°C warming scenario with no wastewater reuse. Water_gap_3_treated_wastewater_reuse: Water gap under 3°C warming scenario with treated wastewater reuse. Water_gap_3_full_wastewater_reuse: Water gap under 3°C warming scenario with full wastewater reuse. Aggregated data (.xlsx) country_level_water_gaps.xlsx: Water gap aggregated by country for all the considered scenarios. city_water_gaps.xlsx: 0.5° pixels with populations greater than 5,000,000 and non-zero water gaps corresponding to urban center. seasonal_variations.xlsx: Monthly water gaps of the 5 most water scarce countries. Note: the global water gap obtained by summing all the countries is not completely equivalent to the sum of all the pixels because some pixels' center is outside the polygon of the corresponding country.本文件夹包含对应学术论文的水资源缺口（water gap）数据，论文信息为：Kahn, M., Sangiorgio, M. 与 Rosa, L. (2025) 《未来变暖情景下污水回用缓解水资源短缺的潜力》，刊载于《Environmental Research Letters》第20卷，文章编号034012，DOI：10.1088/1748-9326/adb31d。 所有水资源缺口数据的单位均为km³/yr（立方千米每年）。 ## 格点数据（0.5°分辨率，格式为NetCDF） ### 基准期（2001-2010年） - Water_gap_baseline_no_wastewater_reuse：基准气候情景下无污水回用场景的水资源缺口 - Water_gap_baseline_treated_wastewater_reuse：基准气候情景下采用处理后污水回用场景的水资源缺口 - Water_gap_baseline_full_wastewater_reuse：基准气候情景下采用全量污水回用场景的水资源缺口 ### 1.5℃增温情景 - Water_gap_15_no_wastewater_reuse：1.5℃增温情景下无污水回用场景的水资源缺口 - Water_gap_15_treated_wastewater_reuse：1.5℃增温情景下采用处理后污水回用场景的水资源缺口 - Water_gap_15_full_wastewater_reuse：1.5℃增温情景下采用全量污水回用场景的水资源缺口 ### 3℃增温情景（包含5个模式及模式平均结果） - Water_gap_3_no_wastewater_reuse：3℃增温情景下无污水回用场景的水资源缺口 - Water_gap_3_treated_wastewater_reuse：3℃增温情景下采用处理后污水回用场景的水资源缺口 - Water_gap_3_full_wastewater_reuse：3℃增温情景下采用全量污水回用场景的水资源缺口 ## 聚合数据（.xlsx格式） - country_level_water_gaps.xlsx：覆盖所有考虑情景的国家级聚合水资源缺口数据 - city_water_gaps.xlsx：包含人口超过500万且水资源缺口非零的0.5°格点数据，对应城市中心区域 - seasonal_variations.xlsx：水资源匮乏程度排名前五的国家的逐月水资源缺口数据 注：对所有国家的水资源缺口求和得到的全球总缺口，与所有格点求和的结果不完全一致，原因是部分格点的中心位于对应国家的多边形边界之外。
