This data comes from three field spectral measurements and three indoor integrating sphere spectral measurements from June 4, 2008 to June 11, 2008. Vertical ground observation and multi angle spectral observation are carried out in the field spectral measurement. The reflectance of spruce bark and the reflectance and transmittance of spruce needles were mainly observed in the indoor integrating sphere spectral measurement.\n
\nThis data set consists of three parts; 1) Original data and preprocessing result data set of ground multi angle and four component spectral measurement in Dayekou forest land. The field multi angle and four component spectral measurements were carried out in the Qinghai Spruce super sample plot in Dayekou small watershed of Heihe River Basin on June 10, 2008 and June 11, 2008. The multi angle spectra (- 60, - 50, - 40, - 30, - 20, - 0, 10, 20, 30, 40, 50, 60 degrees) and four component spectra (light tree crown, shadow tree crown, light ground and shadow ground) of Qinghai Spruce canopy were measured; The main observation instruments are ASD spectrometer, FieldSpec pro (Academy of Forestry), self-made multi angle observation frame (Beijing Normal University), and 1m and 10m optical fibers are used for different purposes. The result data is a normal table file (*. XLS). The data can be used to study the spectral angle characteristics and geometric optical reflection characteristics of different components of Picea crassifolia canopy; 2) Integrating sphere measurement raw data and preprocessing data set. Indoor integrating sphere spectral measurements were carried out on June 5, 2008, June 9, 2008 and June 10, 2008. The reflectance and transmittance of bark and needle of Qinghai Spruce at different ages (mature forest, near mature forest and young forest) and different positions in the super sample plot of Dayekou basin were mainly observed. The main observation instruments are: integrating sphere, Li cor 1800-12s (Beijing Normal University), ASD spectrometer and FieldSpec pro (Academy of Forestry). The data format is special and needs to be opened and processed by ASD viewspecpro software. The processed result data of the original data of integrating sphere spectral measurement is a tabular file, which can be opened with Microsoft Excel. The data can be used to study the changes of bark and needle reflectance of Qinghai Spruce at different tree ages and to develop canopy reflectance model; 3) Preprocessing data set of ground zenith spectrum measurement in Dayekou super sample plot. The field vertical ground spectral measurement was carried out on June 4, 2008, in which the spectra of different ground features and underlying surfaces were measured: including the vertical zenith reflectance spectra of shrubs, forest window meadows, moss, shading moss, litter under the forest, bare land under the forest, different young trees of Qinghai Spruce, large trees of Qinghai Spruce and twigs of Qinghai Spruce; The main observation instruments are ASD spectrometer and FieldSpec pro (Academy of Forestry). 1m and 10m optical fibers were sampled for different purposes. This data can provide ground observation data for forest parameter inversion, and provide necessary information data set for model simulation of canopy reflection characteristics of Qinghai Spruce Forest
