Winter wheat NDVI and NIRv for all 96 Bavarian districts, March-June 2017-2024, from 1.13 TB of DLR Sentinel-2 monthly composites masked with DLR 10 m crop maps. GPU pipeline (CuPy, exactextract) on Colab: 1.64 billion wheat pixels in 5.5 h. Over 151,793 OCO-2 footprints, SIF tracks NIRv (r=0.54) better than NDVI (r=0.42).
