Global Pesticide Grids (PEST-CHEMGRIDS), Version 1.01
收藏资源简介：
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-4 formats.
全球农药栅格数据集（PEST-CHEMGRIDS）V1.01包含20种最常用的农药有效成分，覆盖6种主栽作物与4类汇总作物类别，空间分辨率为5弧分（赤道处约10千米），数据以2015年为基准进行估算，并外推至2020年与2025年。为估算特定有效成分的全球施用速率，本数据集采用空间统计方法，重新分析了美国地质调查局农药国家综合项目（USGS/PNSP）、联合国粮食及农业组织企业统计数据库（FAOSTAT）的农药数据库，同时整合了其他公开数据集，包括全球栅格化的土壤物理性质、水文气候变量、农业量化指标及社会经济指数数据。每种作物上各有效成分的施用速率（APR）单位为千克每公顷每年（kg/ha-year），各作物的收获面积单位为公顷（ha）。本数据集还包含200张数据质量指数图，对应每种作物上的各有效成分，同时附带10种主栽作物与4类汇总作物类别的栅格分布图。V1.01版本的数据存储格式为GeoTIFF与netCDF-4。
