Hyperspectral field spectrometry of Arctic vegetation units in the central Lena Delta
Hyperspectral field measurements were acquired in the central Lena Delta in August 2018. The aim was to conduct spectral surface reflectance surveys of various homogeneous vegetation areas on different permafrost landforms to establish a representative spectral reflectance database. In total, we too...
