Sample data for "A weakly supervised framework for high resolution crop yield forecasts"

This dataset includes sample data for the United States to run the weakly supervised framework as described in the paper titled A weakly supervised framework for high resolution crop yield forecasts, accessible at 

https://doi.org/10.48550/arXiv.2205.09016

The updated paper (including results from the US) is published in Environmental Research Letters:

The software implementation of the machine learning baseline is available at: https://github.com/BigDataWUR/MLforCropYieldForecasting/tree/weaksup.

Data

1. County data (county-data.zip) for county-level strongly supervised models:
