Once the input data has been processed through SPAM the resulted output data is more granular (10 x 10 km grid-cell resolution) and specifically based on the four variables which are calculated by the model: physical area, harvest area, production and yield, for each of the 42 crops, split by rainfed and irrigated production system, as well as the total combination of both.

Please check the methodology section for a thorough explanation.

SPAM generates a large collection of data:
~800.000 pixels X 42 crops X 4 production systems X 4 variables = ~500 million records

Therefore in the Global Data section, we split the choices by crop, production system and variable, and in the Bundled Data section, the files are split by spatial extent (11 world regions) and variable. The Country Data section enables download for a specific country, crop, production system and variable.
Feel free to choose whatever works best for you and contact us with any questions.
