Spectral properties of 16 peatland plant species and litter

This dataset contains reflectance and transmittance data for 16 dominant peatland vascular plant species measured in Finland and Estonia, along with reflectance measurements for peatland litter measured as fresh and dry, across wavelengths ranging from 350 to 2500 nm. For each vascular plant species, a total of nine leaf samples were measured, and for litter, a total of twelve samples were measured. For the vascular plants, the dataset also includes the species, the measured leaf side (adaxial=upper, or abaxial=lower), the measured quantity (directional-hemispherical reflectance factor, DHRF or directional-hemispherical transmittance factor, (DHTF)), the location of the sampling site (peatland name, municipality, country), the measurement date, and the sample ID. For litter, the dataset includes, in addition to the conical-conical reflectance factor (CCRF), the location of the sampling site (peatland name, municipality, country), the measurement date, whether the sample was fresh or dry, and the sample ID.
