XST-FPARNet Fully Automated Photosynthetically Active Radiation meter
Product Overview
产品配置 由冠层上反射辐射节点（长形双面共18探头，用于测量冠层上总辐射和总反射辐射）、冠层下透过辐射节点（长形双面共18探头，用于测量冠层下透射辐射和土壤反射辐射）及汇聚节点组成，是一款基于物联网架构的光合有效辐射联网观测仪器，能够多节点无线组网自动观测，并汇聚数据统一上传服务器。
Product Features 基于自主研发算法，自动计算植被光合有效辐射吸收比率（Fraction of Absorbed Photosynthetically Active Radiation，FPAR），该指标是描述植被结构以及大气-陆面生物圈之间物质与能量交换过程的一个关键变量。
产品优势 监测点布设灵活、抗干扰能力强、测量精度高、功耗低、稳定性好，符合WMO世界气象组织规范（CIMO Guide）。
Application Areas
应用于农林生态科研领域的植被生产力估算、植被生物量估算及遥感产品真实性检验。
