根河生态站森林组分温度多时相实测数据（20160807）

本数据集来源于根河生态保护区复杂地形混交林精细光学遥感试验，实验地点位于根河生态站（内蒙古大兴安岭森林生态系统国家野外科学观测研究站）附近，数据获取时间为2016年8月7日9点-17点（北京时间），采样间隔为0.5小时。测量设备为FLIR T440成像仪，通过图像监督分类提取了光照叶片、阴影叶片、光照树干、阴影树干、光照背景和阴影背景共六种组分的亮度温度。经过反射项贡献的去除和发射率校正最终得到六个组分的辐射温度。本数据集有望应用于热红外建模、组分温度反演、蒸散发估算等方面。

This dataset is derived from a fine-scale optical remote sensing experiment conducted in a mixed forest with complex terrain within the Genhe Ecological Protection Zone. The experiment was carried out near the Genhe Ecological Station (National Field Scientific Observation and Research Station for Forest Ecosystems in the Greater Khingan Mountains, Inner Mongolia Autonomous Region). The data was collected from 9:00 to 17:00 (Beijing Time) on August 7, 2016, with a sampling interval of 0.5 hours. The FLIR T440 thermal imager was used as the measurement device, and brightness temperatures of six components, namely sunlit leaves, shaded leaves, sunlit trunks, shaded trunks, sunlit backgrounds, and shaded backgrounds, were extracted through image supervised classification. After removing the contribution of reflected radiation and conducting emissivity correction, the radiant temperatures of the six components were finally obtained. This dataset shows promising applications in thermal infrared modeling, component temperature retrieval, evapotranspiration estimation, and other relevant research areas.
