该数据集包含2014年07月23日至2014年08月18日在黑河下游混合林站和超级站观测的热像仪组分温度数据。观测地点坐标分别为101.1335E、41.9903N和101.1374E、42.0012N，海拔约874m。\n
\n在混合林站和超级站分别使用Testo890-2（热红外图像：640 × 480，可见光2048 × 1536）和Testo875-2i（热红外图像：160 × 120，可见光640 × 480）热像仪，以通量塔为中心，在10m高度处，拍摄塔周围的地表亮温和可见光图像。在混合林站的观测方向为东北、东、东南、西南和西北，在超级站的观测方向为东北、东南、西南和西北。\n
\n观测时间范围主要为晴空日期的10:00至16:00；各次的观测时间为整点和MODIS、Landsat 8过境时；8月4日的拍摄为配合航空飞行，观测间隔约为10min。
