Dataset for paper "Marked impacts of pollution mitigation on crop yields in China"

"corn.csv", "winterwheat.csv" and "midlatepaddy.csv" report historical crop yield (unit: kg/hectare)of corn, winter wheat and single cropping rice in China. <br> "regression.ipynb" contains python code to (i) derive the sensitivity of crop yield to climate and pollution variables (ii) compare predicted yield vs. observed yield (iii) calculate the relative contribution of individual climate and pollution variables to inter-annual variations of crop yield. Here we provide the complete datasets for corn in file “organized_data_corn.csv”, which includes air temperature at 2m (t2m), precipitation (tp), aerosol optical depth (aod) and surface ozone (o3) for plant season (plant), growing season (mid) and harvest season (harvest). Please contact us if you are interested in datasets of other two crop species."corn.csv"、"winterwheat.csv"与"midlatepaddy.csv"记录了中国境内玉米、冬小麦以及单季稻的历史作物产量，单位为千克每公顷（kg/hectare）。"regression.ipynb"包含可实现以下功能的Python代码：(1) 推导作物产量对气候与污染变量的敏感性；(2) 对比预测产量与实测产量；(3) 计算单个气候与污染变量对作物产量年际变化的相对贡献。本次我们在"organized_data_corn.csv"文件中提供了完整的玉米数据集，该数据集涵盖播种季（plant）、生长季（mid）与收获季（harvest）的2米气温（air temperature at 2m, t2m）、降水量（precipitation, tp）、气溶胶光学厚度（aerosol optical depth, AOD）以及地表臭氧（surface ozone, O3）数据。若您需要另外两种作物的数据集，请与我们联系。
