Data for Deines, Wang, & Lobell 2019 analysis on tillage and yields

Data needed to reproduce the original analyses and figures from Deines et al. 2019 "Satellites reveal a small positive yield effect from conservation tillage across the US Corn Belt" (https://doi.org/10.1088/1748-9326/ab503b) can be found in the zipped `data` folder. This includes the field-level samples derived from the input annual tillage and yield map datasets, along with associated covariates. Due to privacy concerns, field locations are reported by county only (latitude and longitude have been removed), and the input map datasets are not publicly available but may obtained from their sources upon reasonable request. Unzipped file is ~11.3 gb; data is provided in a zipped folder to preserve file structure for best use with associated code repository located at https://doi.org/10.5281/zenodo.3525359.
