cff-version: 1.2.0 abstract: "Grassland (Lolium perenne) dry aboveground biomass, nitrogen content (N%) and N uptake (t ha-1) measured in experimental plots located near the city of Kleve, in Germany. These measurements correspond to five harvest dates, two in 2014 and three in 2017. In addition, UAV flights were performed on the same dates in the experimental site to acquire hyperspectral images, using the WageningenUR Hyperspectral Mapping System (HYMSY), a pushbroom imaging sensor comprising a spectrometer and a photogrammetric camera." authors: - family-names: Kooistra given-names: Lammert orcid: "https://orcid.org/0000-0001-5549-5993" - family-names: H D Franceschini given-names: Marston orcid: "https://orcid.org/0000-0002-1295-4798" - family-names: Becker given-names: Rolf orcid: "https://orcid.org/0000-0002-2150-0982" - family-names: Wichern given-names: Florian - family-names: Suomalainen given-names: J.M.
