AWI CANON Sea ice image albedo retrieval calibration files

The dataset contains calibration data, compiled for a Python based retrieval of a broadband albedo estimate from CANON EOS-1D Mark III cameras deployed as aerial imaging system over Arctic sea ice. It contains information on the relative spectral response function of the camera sensor (RSR_CANON), calibration coefficients to convert spectral albedo in the three RGB color bands into broadband albedo under different sky conditions (spec2broad_params) and calibration coefficients to convert RGB intensity into radiance dependent on exposure settings (Calib_coefficients_14mm_diff_settings).本数据集包含校准数据，此类数据为支持基于Python从作为航空成像系统部署于北极海冰上空的佳能（CANON）EOS-1D Mark III相机中开展宽带反照率估算值的反演任务而编制。数据集包含相机传感器的相对光谱响应函数（Relative Spectral Response Function）相关数据（RSR_CANON）、可将RGB三波段的光谱反照率转换为不同天空条件下宽带反照率的校准系数（spec2broad_params），以及可根据曝光设置将RGB亮度值转换为辐射亮度的校准系数（Calib_coefficients_14mm_diff_settings）。
