Global Pesticide Grids (PEST-CHEMGRIDS), Version 1.01

The Global Pesticide Grids (PEST-CHEMGRIDS), Version 1.01 data set contains 20 of the most-used pesticide active ingredients on 6 dominant crops and 4 aggregated crop classes at 5 arc-minute resolution (about 10 km at the equator), estimated in year 2015, and then projected to 2020 and 2025. To estimate the global application rates of specific active ingredients, spatial statistical methods were used to re-analyze the U.S. Geological Survey Pesticide National Synthesis Project (USGS/PNSP) and the Food and Agriculture Organization Corporate Statistical Database (FAOSTAT) pesticide databases, along with other public inventories including globally gridded data of soil physical properties, hydro-climatic variables, agricultural quantities, and socioeconomic indices. The application rate (APR) of each active ingredient on each crop is in kilogram per hectare per year (kg/ha-year), and the harvest area of each crop is in hectare (ha). The data set also includes 200 data quality index maps corresponding to each active ingredient on each crop, as well as maps of the 10 dominant crops and 4 aggregated crop classes. Version 1.01 includes data in GeoTIFF and netCDF formats.

《全球农药网格数据集》（PEST-CHEMGRIDS）版本1.01收录了20种在6种主要作物及4个综合作物类别中最常用的农药活性成分，以5弧分钟分辨率（约相当于赤道附近10公里）进行估算，数据回溯至2015年，并预测至2020年和2025年。为估算特定活性成分的全球应用率，本研究采用了空间统计方法，对美国地质调查局农药国家综合项目（USGS/PNSP）及联合国粮食及农业组织企业统计数据库（FAOSTAT）的农药数据库进行了重新分析，并结合了包括全球网格化土壤物理特性、水文气候变量、农业产量以及社会经济指数等在内的其他公开清单。每个活性成分在每个作物上的应用率（APR）以每公顷每年千克（kg/ha-year）为单位计量，而每个作物的收获面积以公顷（ha）为单位。该数据集还包括与每个活性成分在每个作物上对应的质量指数地图，以及10种主要作物和4个综合作物类别的地图。版本1.01包含GeoTIFF和netCDF格式的数据。
