本数据为黑河中游盈科绿洲与湿地、戈壁、沙漠观测的典型地物比辐射率数据集。数据观测从2012年5月25日至2012年7月18日。\n
\n仪器：北京师范大学便携式傅立叶变换红外波谱仪（102F）、手持式红外温度计\n
\n测量方法：利用102F分别测量冷黑体、暖黑体、观测目标、金版的辐射值。利用冷暖黑体的辐射值，对102F进行定标，消除仪器自身发射的影响。利用基于平滑度的迭代反演算法，反演出比辐射率和物体温度。比辐射率波段范围为8-14μm，分辨率4cm-1。\n
\n本数据集包含102F获取的冷黑体、暖黑体、被测目标和金板的原始辐射曲线（ASCII格式）和记录文件。处理后的数据为8-14μm比辐射率曲线（ASCII格式）.部分数据配套有被测目标的热像仪照片，数码相机拍摄的场景和被测物体图像。

\nInstruments: Portable Fourier transform infrared spectrometer (102f) and handheld infrared thermometer of Beijing Normal University\n
\nMeasurement method: use 102f to measure the radiation values of cold blackbody, warm blackbody, observation target and gold plate respectively. Using the radiation value of cold and warm blackbody, 102f is calibrated to eliminate the influence of instrument emission. The specific emissivity and object temperature are inversed by using the iterative inversion algorithm based on smoothness. The band range of specific emissivity is 8-14 μ m. Resolution 4cm-1.\n
