Tree species profiles from Sentinel-2 time series

Tree species profiles from Sentinel-2 time series We obtained tree species-specific Sentinel-2 time series for the years 2019 and 2020. The Sentinel-2 time series originated from [here](https://www.envidat.ch//metadata/sentinel-2-time-series-of-switzerland), and the tree species information was derived from pure plots of the Swiss National Forest Inventory, spread all over Switzerland. In addition to the 10 and 20 m bands from Sentinel-2 (Blue, Green, Red, Red-Edge-1, Red-Edge-2, Red-Edge-3, NIR, SWIR-1, SWIR-2), we calculated indices (CCI, CIre, EVI, NDMI/NDWI, NDVI). In total, tree species profiles of 763 pixels for 2020 and 562 pixels for 2019 are available for seven tree species (*Abies alba*, *Castanea sativa*, *Fagus sylvatica*, *Fraxinus excelsior*, *Larix* spp., *Picea abies*, *Pinus sylvestris*).

基于哨兵2号（Sentinel-2）时序影像的树种特征数据集。本研究获取了2019年与2020年的树种专属哨兵2号时序数据，该数据集源自[此处](https://www.envidat.ch//metadata/sentinel-2-time-series-of-switzerland)，树种信息提取自遍布瑞士全境的瑞士国家森林调查纯林样地。除哨兵2号搭载的10米与20米分辨率波段（蓝光、绿光、红光、红边1、红边2、红边3、近红外（NIR）、短波红外1（SWIR-1）、短波红外2（SWIR-2））外，本研究还计算了CCI、CIre、EVI、NDMI/NDWI、NDVI等植被指数。最终，针对欧洲冷杉*Abies alba*、欧洲板栗*Castanea sativa*、欧洲山毛榉*Fagus sylvatica*、欧洲白蜡树*Fraxinus excelsior*、落叶松属*Larix* spp.、欧洲云杉*Picea abies*、欧洲赤松*Pinus sylvestris*这7个树种，本数据集共包含2020年763个像元、2019年562个像元的树种特征数据。
