A time-series of leaf-level optical hyperspectral reflectance captured using a leaf-clip and handheld spectrometer for 17 herbaceous species typical of chalk grassland habitat in Kent UK, over 13 sampling dates in 2021. Data were collected using a non-imaging spectrometer manufactured by Spectra-vista Corporation fitted with a leaf-clip; capturing reflectance from 350 - 2500nm. Funded by NERC Grant NE/L002566/1.
