Modelled annual average production loss due to ozone damage for four global staple crops 2010-2012

Modelled annual average production loss (thousand tonnes per 1 degree by 1 degree grid cell) due to ground-level ozone pollution is presented for the crops maize (Zea mays), rice (Oryza sativa), soybean (Glycine max) and wheat (Triticum aestivum), for the period 2010-2012. Data are on a global scale, based on the distribution of production for each crop, according to the Food and Agriculture Organisation’s (FAO) Global Agro-Ecological Zones (GAEZ) crop production data for the year 2000. Modelled ozone data (2010-2012) needed for production loss calculations were derived from the EMEP MSC-W (European Monitoring and Evaluation Programme, Meteorological Synthesising Centre-West) chemical transport model (version 4.16). Mapping the global crop production losses due to ozone highlights the impact of ozone on crops and allows areas at high risk of ozone damage to be identified, which is a step towards mitigation of the problem. The production loss calculations were done as part of the NERC funded SUNRISE project (NEC06476) and National Capability Project NC-Air quality impacts on food security, ecosystems and health (NEC05574).

本数据集展示了由于地面臭氧污染导致的作物年度平均产量损失（以每1度经纬度网格单元每千吨计），涵盖了玉米（Zea mays）、水稻（Oryza sativa）、大豆（Glycine max）和小麦（Triticum aestivum）等作物，数据时间范围为2010-2012年。数据基于全球尺度，根据联合国粮食及农业组织（FAO）的全球农业生态区（GAEZ）作物生产数据（2000年），针对每种作物的生产分布进行编制。用于产量损失计算所必需的模拟臭氧数据（2010-2012年）由欧洲监测与评估计划（EMEP）气象综合中心-西（MSC-W）化学传输模型（版本4.16）提供。通过绘制全球作物因臭氧导致的产量损失图，凸显了臭氧对作物的影响，并有助于识别高臭氧损害风险区域，这对于问题的缓解措施是一个重要步骤。产量损失的计算作为NERC资助的SUNRISE项目（项目编号NEC06476）和国家能力建设项目“空气质量对粮食安全、生态系统和健康的影响”（项目编号NEC05574）的一部分完成。
