Forward-Looking Climate Modelling for Western Athens

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 domain focus on the metropolitan area of Athens, Greece. More details about the dataset: The dataset includes calculations for each indicator across three scenarios (<strong>present, SSP1-1.9, SSP3-7.0</strong>) and three twenty-year periods (<strong>2001-2020, 2021-2040, and 2041-2060</strong>). The present period refers to 2001-2020, while the other two periods correspond to the two SSP scenarios. All indicators are available in both <strong>NetCDF</strong> and <strong>GeoTiff</strong> formats. The indicators are calculated at a resolution of <strong>150 m</strong>, consistent with the UrbClim and WBGT simulations. Additionally, downscaled versions of the indicators are provided at a resolution of <strong>30 m</strong>. The UrbClim and WBGT simulations, as well as the postprocessing, are conducted using the regional projection <strong>EPSG 32634</strong>. The NetCDF and GeoTiff data also adopt this projection. Furthermore, a GeoTiff data file with <strong>EPSG 4326</strong> projection is included. All indicators are calculated as <strong>yearly averages</strong>. Some indicators also have additional calculations for <strong>seasonal averages</strong>, including Spring (MAM), Summer (JJA), Autumn (SON), and Winter (DJF). Images for <strong>quick viewing</strong> <strong>in</strong> <strong>png</strong> format visualizing the results for each indicator. Present denotes the period 2001-2020; 2030 denotes the period 2021-2040; &amp; 2050 denotes the period 2041-2060. The images are also clipped to focus on the ASDA municipalities, in which case the png files will be ended with ‘_clip.png’ The NetCDF and GeoTiff data can be found in the data.zip; The png files for quick viewing can be found in quickview.zip; more information about the dataset, including the methodology, all available data list, contact information, etc. can be found in the Technical_Annex_Athens_ver4.docx

我们针对城市热应力生成了可落地的实用数据，以供世界银行（World Bank）团队开展相关分析及与客户的沟通工作。我们采用城市尺度气候建模框架，生成了基于选定气候情景下当前及未来状态的热应力暴露模拟数据集，研究区域聚焦于希腊雅典大都会区。数据集详细信息如下：数据集包含三类情景（当前情景、SSP1-1.9、SSP3-7.0）与三个二十年时段（2001-2020、2021-2040、2041-2060）下各指标的计算结果。其中当前时段对应2001-2020年，其余两个时段分别匹配两个SSP情景。所有指标均提供NetCDF与GeoTiff两种格式的数据。指标计算分辨率为150米，与UrbClim及湿球黑球温度（Wet Bulb Globe Temperature, WBGT）模拟结果保持一致。此外，数据集还提供分辨率为30米的降尺度指标数据。UrbClim与WBGT模拟及后续后处理步骤均采用EPSG 32634区域投影坐标系，NetCDF与GeoTiff数据也沿用该坐标系。此外，数据集还包含采用EPSG 4326投影坐标系的GeoTiff数据文件。所有指标均以年平均值形式计算，部分指标还额外提供季节平均值结果，涵盖春季（MAM）、夏季（JJA）、秋季（SON）及冬季（DJF）。数据集附带用于快速预览的各指标结果可视化PNG格式图像。其中“当前情景”对应2001-2020年，“2030”代表2021-2040年，“2050”代表2041-2060年。部分预览图已裁剪至仅覆盖ASDA自治市范围，此类PNG文件的文件名后缀为“_clip.png”。NetCDF与GeoTiff格式数据可于data.zip压缩包中获取；快速预览PNG文件可于quickview.zip压缩包中获取；关于数据集的更多信息，包括研究方法、全部可用数据清单、联系方式等，均可在Technical_Annex_Athens_ver4.docx文档中查阅。
