包头核心定标场太阳反射谱段地面观测真值样本数据(2021.10 -12)

该数据集由地面高光谱辐亮度数据、地表高光谱总照度数据、地表多光谱辐亮度数据组成，对应的场地为包头核心定标场的18%反射率固定靶标和包头沙地场。利用这些数据可以获得两种场地的高光谱反射率数据和多光谱反射率数据，可以为高分辨卫星进行长序列的在轨定标计算与验证。

This dataset comprises ground-based hyperspectral radiance data, surface hyperspectral total irradiance data, and surface multispectral radiance data. The corresponding calibration sites include the 18% reflectance fixed target at the Baotou Core Calibration Site and the Baotou Sandy Land Site. These data can be used to derive hyperspectral and multispectral reflectance data for both sites, enabling long-term on-orbit calibration calculations and validations for high-resolution satellites.
