DATASET OVERVIEW
将数据从SPAM转移到0.1 degreeg grid cells，为进行全球农业和天气分析出作物空间分配基本模式。原数据是cell5m数据（ha,ton,kg/ha），转移到0.1度后，原数据harv_area/phys_area/prod 不再准确，只有yield不变，使用时需要验证数据准确度。

SPAM:Using a variety of inputs, IFPRI’s Spatial Production Allocation Model (SPAM) uses a cross-entropy approach to make plausible estimates of crop distribution within disaggregated units.
