Soil Water-Holding Capacity Moderates Corn Yield Sensitivity to Compound Heat–Drought Extremes in U.S. Rainfed Production

Note

The authors specify that 2026 is incomplete and should be excluded, leaving a valid analysis window of 2000–2025). Key Variables: Yield Metrics: Corn yield anomalies and production data. Climatic Variables: Annual precipitation, daily maximum/minimum temperatures, evapotranspiration, and solar radiation.

Soil Parameters: Soil pH and indices related to water-holding capacity (buffering). Provenance/Nature: This is a secondary, pre-compiled collection. It does not contain raw daily station-level weather data or field-level soil samples.

Instead, it provides the “as-supplied” aggregated panel required for the fixed-effects OLS regression models described in the Reproduction_Steps sheet. Documentation: The workbook includes dedicated sheets (README, Pipeline_Map, Reproduction_Steps) that map the raw source columns to the analytical variables used in the original research, ensuring transparency in how the data was cleaned and transformed.
