Agricultural University of Athens Green Roof Lysimeters Dataset

This dataset documents hydrological, soil, and meteorological measurements collected at the Green Roof Lysimeters Facility of the Agricultural University of Athens (AUA). The facility consists of thirty thermally insulated rooftop lysimeters located on the Library building of AUA (Iera Odos 75, Athens, Greece; 37.984460° N, 23.706663° E, elev. 40 m). The dataset was generated to analyze rainfall–runoff dynamics, infiltration capacity, and substrate water retention under varying green roof configurations in a Mediterranean climate. Measurements were obtained within the Urban BioRoof project (code 12CHN136) funded by the Hellenic General Secretariat of Research and Innovation. Monitoring included: Rainfall and runoff via tipping bucket collectors and rain gauges. Substrate moisture and temperature using Turfguard™ dielectric wireless sensors (TORO, USA) with substrate-specific calibration (accuracy ±0.01 cm³ cm⁻³). Meteorological parameters (air temperature, humidity, wind speed, solar radiation, evapotranspiration) from a nearby weather station (~1 km from the site). The lysimeters were configured with two substrate depths (8 cm and 16 cm) and planted with three vegetation types, Festuca arundinacea (turfgrass), Sedum sediforme (succulent), and Origanum onites (xerophyte), plus bare and non-vegetated controls. Each treatment was replicated four times.本数据集记录了雅典农业大学（Agricultural University of Athens, AUA）绿色屋顶蒸渗仪设施的水文、土壤与气象观测数据。该设施设于该校图书馆楼宇楼顶，共包含30台隔热型屋顶蒸渗仪，具体位置为希腊雅典伊拉欧多斯75号（37.984460° N, 23.706663° E，海拔40米）。 本数据集旨在分析地中海气候下不同绿色屋顶配置的降雨-径流动态、入渗能力与基质持水性能，其依托希腊研究与创新总秘书处资助的城市生物屋顶项目（项目编号12CHN136）生成。 监测内容包括： 1. 通过翻斗式收集器与雨量计获取降雨与径流数据； 2. 采用Turfguard™介电式无线传感器（美国TORO公司）测定基质含水率与基质温度，该传感器针对实验基质进行了专属校准，测量精度可达±0.01立方厘米每立方厘米； 3. 依托场地周边约1公里处的气象站获取气象参数，包括气温、相对湿度、风速、太阳辐射与蒸散发量。 本次实验所用蒸渗仪设置了两种基质厚度（8厘米与16厘米），并种植了3种植被：Festuca arundinacea（高羊茅，草坪草）、Sedum sediforme（多肉植物）、Origanum onites（旱生植物），同时设置裸地与无植被对照组。每种处理均设置4次重复。
