The African Gridded Yield Dataset (AGYD)

The African Gridded Yield Dataset (AGYD) was constructed at a spatial resolution of 5 arcmin (approximately 10 km) for the years 2000, 2005, 2010, 2015, and 2020 by integrating existing crop yield datasets through Bayesian model averaging (BMA), using subnational observational yield data from the GROW-Africa database as reference data.非洲网格化产量数据集（African Gridded Yield Dataset, AGYD）以5角分（约10公里）为空间分辨率，涵盖2000、2005、2010、2015及2020年的数据；该数据集通过贝叶斯模型平均（Bayesian model averaging, BMA）整合现有作物产量数据集构建而成，构建过程中采用GROW-Africa数据库的次国家级观测产量数据作为参考数据。
