Multi-source 8-day Composite Dataset for County-level Soybean Yield Modeling in the U.S. Corn Belt

This dataset provides multi-source remote sensing and meteorological variables for county-level soybean yield modeling across the U.S. Corn Belt. The dataset includes: 8-day composite EVI2 derived from MODIS surface reflectance 8-day composite soil moisture 8-day cumulative precipitation, and 8-day mean maximum and minimum temperature from Daymet All variables aggregated to the county level using soybean pixels only The temporal coverage spans the soybean growing season for each year, and each variable is provided as a fixed-length time series per county.
