Maize Phenometrics

Dataset include Land Surface Phenology metrics for maize, with Start-of-Season (SOS) related to maize emergence and shooting phenological stages, Peak-of-Season (POS) related to tip of tassel emergence, and End-of-Season (EOS) related to dough ripening and harvest. Using multiple vegetation indices (Normalized Difference Vegetation Index, Normalized Difference Phenology Index, Normalized Difference Red Edge, Modified Soil-Adjusted Vegetation Index) and retrieval methods (First-of-Slope, Median, Relative-Amplitude, and Seasonal-Amplitude), three maize phenometrics (SOS, POS, EOS) were derived from Sentinel-2 (S2) and Fused datasets (fusion of Sentinel-2 and PlanetScope data) for years 2021 and 2022. The pixel values refer to Day-of-Year (DOI) per phenological stage, clipped by fields and structured per test site and year.
Note: This dataset consists of many rasterdata within a zipfile. Please start the download as csv and our server will compile a zip package.
