High-resolution fused crop data products

[Amos Tai]

Hi folks,

These are the data for cropland fraction as well as harvested area, production, yield and calendar for four crops (wheat, rice, maize, soybean) that were used for Tai & Val Martin [2017] (which were newer than those used in Tai et al. [2014] due to the incorporation of USDA state-level data for the US):

Cropland fraction:
