本数据为黑河流域典型地物比辐射率数据集。数据观测从2014年3月25日至2015年6月30日。\n
仪器：便携式傅立叶变换红外波谱仪（102F）、手持式红外温度计\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
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。", "ds_source": "

Instruments: Portable Fourier transform infrared spectrometer (102f), hand-held infrared thermometer\n
Measurement 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
This data set contains the original radiation curves (ASCII format) and recording files of cold blackbody, warm blackbody, measured target and gold plate obtained by 102f.
