FIP1 – Winter Wheat Field Phenotyping

This dataset is a structured extract from the FIP 1.0 dataset (Boss, Roth & Kirchgessner, ETH Zurich, 2024; doi:10.3929/ethz-b-000697773), prepared for use in causal structure learning analyses of winter wheat growth and yield formation. It was used in the study “Hierarchical Causal Structure Learning” (Hermes et al., arXiv:2511.20021). The data covers more than 4,000 individual wheat plots grown across six seasons (2016–2018, 2019–2022) at the ETH Field Phenotyping Platform in Zurich, Switzerland. Each row corresponds to one plot in one growing season. The dataset contains nine variables spanning environmental drivers and plant phenotypic traits, described below. Environmental variables are provided as hourly time series over the full growing year; phenotypic traits are provided as scalar summaries or sparse time series depending on the measurement type. The data is structured in Parquet format to preserve the nested time series structure. The six splits (train, validation, test_plot, test_genotype, test_environment, test_genotype_environment) follow the benchmark splits defined in the FIP 1.0 HuggingFace release (doi:10.57967/hf/3191).
Task: The dataset can be used to study causal discovery methods.

Features:
- Solar irradiance — Hourly incoming solar radiation measured at 200 cm above ground (W/m²). Recorded by the FIP meteorological station throughout the growing year. Drives photosynthesis and crop energy balance.
- Precipitation — Hourly precipitation measured at 200 cm above ground (mm). Recorded by the FIP meteorological station. A key water input variable for crop growth and yield formation.
- Air temperature — Hourly air temperature measured at 200 cm above ground (°C), the standard meteorological screen height. Controls the rate of crop development, including heading timing and grain filling.
- Days till heading — Scalar. The number of days from sowing to the heading date (the moment when the wheat ear emerges from the flag leaf sheath). A key phenological trait reflecting genotype-specific and temperature-driven developmental timing.
- Height — Final pla
