Reflectance spectra measured with ASD field spectrometer and ground truthing of vegetation heights and phenology for different crops and bare soil at the Hordorf (Central Germany) ground truthing sites

The data were taken to obtain information on soil and vegetation information at ground surface. That included (1) measurements of soil moisture, soil temperature and surface temperature of a 40 m x 40 m stubble field west of the flux tower station Hordorf (Central Germany); (2) the measurements of soil moisture, soil temperature and surface temperature as well as spectra taken with an Analytical Spectral Devices (ASD) field spectrometer of a bare soil reference area close to flux tower station: (3) measurements of soil moisture, soil temperature, field spectra with ASD field spectrometer, height of plant height, chlorophyll content and pheno-code on crop fields (sugar beet, potatoes) close to flux tower station and (4) the available ASD data files. Alle data points are merged with its GPS coordinates.The time base is CET, except of the ASD field spectra, where CEST was used.
