AI model jointly retrieves wheat crop data using satellite imagery

Researchers have developed an Iterative Energy-Based Transformer (iEBT) model to jointly retrieve soil moisture, leaf area index, and plant height for wheat crops using satellite data. This multimodal transformer processes time series from Sentinel-1 radar and Sentinel-2 optical imagery, iteratively refining estimates by minimizing a learned energy function. The model achieved strong performance with an R^2 of 0.854 on field measurements from India, demonstrating that Sentinel-1 data is crucial for soil moisture retrieval, Sentinel-2 for leaf area index, and a combination for plant height. The model's terminal energy function also serves as a quality diagnostic, allowing for improved accuracy when high-energy samples are excluded. AI

IMPACT This model could enhance precision agriculture by providing more accurate and integrated crop status monitoring using readily available satellite data.
