WRF-Chem output- concentrations for the 4 simulations: reference, urbanization, extension of agricultural areas and more urban parks

We use the WRF-Chem air-quality model with an urban canopy scheme to investigate how land use (urban, agriculture, parks) affects the urban climate and chemical processes (dry deposition, biogenic emissions), resulting in changes in air quality for scenarios proposed by the Urban Master Plan of the Metropolitan Area of Barcelona. We selected a heatwave period, 4th-7th July 2015, with maximum temperatures reaching 40 °C in the interior of the AMB and 35 °C on the coast. Here we provide averaged model output for the heatwave period for the different pollutants, surface temperature, wind speed, PBLH, deposition, and biogenic emissions under different urban scenarios: reference (REF), urbanization (URB), extension of agriculture (AGR), and increase in urban parks (PARK).The results for a period before the heatwave (1-3 July 2015), with temperatures 3-4 degrees lower than during the heatwave, are also provided. Land-use and irrigation is also provided for each scenaio.本研究采用耦合城市冠层方案的WRF-Chem大气化学模式，探究土地利用类型（城市用地、农业用地、公园绿地）对城市气候与化学过程（干沉降、生物源排放）的影响，进而分析巴塞罗那大都市区（Metropolitan Area of Barcelona，简称AMB）城市总体规划提出的不同情景下的空气质量变化。研究选取2015年7月4日至7日的热浪时段，该时段内AMB内陆最高气温达40℃，沿海区域最高气温为35℃。本数据集提供了不同城市情景下热浪时段的平均模型输出结果，包括各类污染物、地表温度、风速、行星边界层高度（PBLH）、沉降通量与生物源排放：基准情景（REF）、城市化情景（URB）、农业扩张情景（AGR）以及城市公园扩容情景（PARK）。本数据集同时提供了热浪前时段（2015年7月1日至3日，该时段气温较热浪时段低3~4℃）的模拟结果。各情景下的土地利用与灌溉数据亦一并提供。
