Dataset accompanying the publication: Climate adaptive solution for artificial turf in cities: integrated rainwater storage and evaporative cooling

This dataset is related to a study performed to test a system for rainwater storage below artificial turf and evaporative cooling of artificial turf. The dataset contains results of a field experiment in Amsterdam, the Netherlands. The field experiment included measurements of meteorological variables, like temperature, precipitation, and radiation, for natural grass, cooled artificial turf and conventional artificial turf.<br>This dataset is a result of the TKI project CitySports and is co-financed with PPS funding from the Topconsortia for Knowledge &amp; Innovation (TKI’s) of the Ministry of Economic Affairs and Climate.<br>Abstract of the paper:The number of artificial turf fields in cities has increased due to increased pressure on outside sport facilities caused by a higher population density. Downsides of these fields are changes in thermal conditions and decreased infiltration of rain. Artificial turf can reach very high surface temperatures leading to unfavourable playing conditions and contributing to the urban heat island effect. In this study the possibilities of a subsurface water storage and capillary irrigation system for evaporative cooling of artificial turf based on rainwater capture, storage and reuse are investigated. The system consists of an 85 mm water-retention subbase with capillary columns, a capillary shockpad and a natural infill. First, a laboratory experiment was conducted to test the evaporative potential of the system with different types of infill and artificial turf. Next, four research plots were designed in Amsterdam, The Netherlands, which consisted of natural grass, conventional artificial turf and two versions of the cooled artificial turf system (non-infill and standard). Evaporation from the cooled artificial turf reached maximum values around 4 mm/d during summer and surface temperatures were significantly lower than at the conventional artificial turf. Rainwater was stored below the fields. By combining these functions, these fields can help cities adapt to climate change.

本数据集源自一项旨在测试人工草坪（artificial turf）地下雨水存储与人工草坪蒸发冷却系统的研究，包含荷兰阿姆斯特丹开展的一项田间试验的结果。该田间试验针对天然草坪、冷却型人工草坪与常规人工草坪，开展了温度、降水、辐射等气象变量的监测。

论文摘要：随着城市人口密度提升，户外体育设施承载压力增大，城市内人工草坪球场的数量持续增长。但这类球场存在诸多弊端：改变了场地热环境，且降低了雨水下渗能力。人工草坪表面温度可攀升至极高水平，不仅会造成运动体验不佳，还会加剧城市热岛效应（urban heat island effect）。本研究针对基于雨水收集、存储与再利用的人工草坪蒸发冷却地下储水及毛细灌溉系统的应用可行性展开探究。该系统包含搭载毛细柱的85毫米保水基层、毛细减震垫以及天然填充料。首先，研究团队开展了室内试验，针对不同填充料与人工草坪组合的系统蒸发性能进行测试。随后，在荷兰阿姆斯特丹搭建了四块试验样地，分别为天然草坪、常规人工草坪，以及两款冷却型人工草坪系统（无填充型与标准型）。夏季期间，冷却型人工草坪的蒸发量最高可达约4毫米/日，其表面温度显著低于常规人工草坪。雨水可存储于场地下方。通过整合上述功能，此类球场可助力城市应对气候变化。
