Tower-based solar-induced fluorescence and vegetation index data for Southern Old Black Spruce forest

Data includes remote sensing products from PhotoSpec (a scanning spectrometer) from September 2019-December 2020 at the Southern Old Black Spruce site in Saskatchewan Canada. We provide half-hourly averaged vegetation indices (NIRv, NDVI, PRI, CCI) and solar-induced fluorescence (SIF) and for a stand-representative mix of black spruce and larch. Additionally, we provide photosynthetically active radiation (PAR), absorbed photosynthetically active radiation (APAR), and the escape fraction of SIF photons (fesc). Version 2 also provides half-hourly averaged SIF and SIFrelative for black spruce (evergreen) and larch (deciduous) separately.本数据集涵盖加拿大萨斯喀彻温省南部老黑云杉林观测站点2019年9月至2020年12月期间，由PhotoSpec扫描光谱仪（scanning spectrometer）获取的遥感产品。本次公开的数据包含针对林分代表性混交黑云杉与落叶松的每半小时平均植被指数（近红外植被指数NIRv、归一化差分植被指数NDVI、光化学反射指数PRI、冠层叶绿素含量指数CCI）与太阳诱导叶绿素荧光（solar-induced fluorescence, SIF）。此外，数据集还提供光合有效辐射（photosynthetically active radiation, PAR）、吸收光合有效辐射（absorbed photosynthetically active radiation, APAR）以及SIF光子逃逸率（escape fraction of SIF photons, fesc）。版本2还分别针对常绿的黑云杉与落叶的落叶松，提供了每半小时平均的SIF与相对SIF（SIFrelative）。
