Canopy Chlorophyll Content for the Bavarian Forest National Park

The canopy chlorophyll content for the Bavarian Forest National Park (BFNP) in Germany at 10 meters resolution on monthly basis for the year 2020. Dataset generated under Showcase. 4, pilot 4.3 myVARIABLE of the e-shape project. Canopy Chlorophyll Content (CCC) is the total amount of chlorophyll a and b pigments in a contiguous group of plants per unit ground area often expressed in mg/m2 (Gitelson et al., 2005). It is a product of leaf chlorophyll content (i.e., the chlorophyll content of a fresh green leaf divided by its one-side area (µmg/cm2)) and the leaf area index. CCC is a terrestrial ecosystem function EBV that describes the distribution of chlorophyll pigments within the 3D canopy surface. This defines the total photosynthetically active radiation absorbed by the canopy (Gitelson et al., 2003; Ustin et al., 2009). The chlorophyll content is one of a constellation of co-evolved traits that vary together across species in relation to contrasting environmental conditions (Reich et al., 2003). Monitoring the dynamics of the CCC helps to understand the adaptation of forest, crop, and other plant canopies to such factors (Feret et al. 2017). As a result, the amount and spatial distribution of chlorophyll content is vital for measuring and understanding plant growth, ecosystem primary productivity and ecosystem dynamics.

德国巴伐利亚森林国家公园（BFNP）2020年逐月、10米分辨率的冠层叶绿素含量数据集。该数据集由e-shape项目的Showcase.4、pilot4.3 myVARIABLE生成。冠层叶绿素含量（CCC）指单位地面面积上连续植物群中叶绿素a和b的总量，通常以mg/m²为单位（Gitelson等，2005）。它是叶片叶绿素含量（即新鲜绿叶的叶绿素含量除以其单侧面积（µmg/cm²））与叶面积指数的乘积。它是一种陆地生态系统功能EBV，描述三维冠层表面内叶绿素色素的分布。这决定了冠层吸收的总光合有效辐射（Gitelson等，2003；Ustin等，2009）。叶绿素含量是协同进化性状集合中的一员，这些性状在不同物种间随环境条件的差异而共同变化（Reich等，2003）。监测CCC的动态有助于理解森林、作物及其他植物冠层对这些因素的适应性（Feret等，2017）。因此，叶绿素含量的总量及其空间分布对于衡量和理解植物生长、生态系统初级生产力及生态系统动态至关重要。参考文献可在注释字段中找到。
