A dataset of JLS-5-20M black soil image in Northeast China

This dataset is the surface reflectance data covering some black soil areas in the three northeastern provinces of China, based on the L1 data of the JL1GP satellites’ multispectral imager with a spatial resolution of 5-20 meters. Specifically, on-orbit absolute calibration technology based on multiple stable sites are adopted, to make on-orbit absolute radiometric calibration accuracy of the JL1GP satellites’ multispectral imagers better than 7%. Then, The L1 data of JL1GP satellite multispectral imager that imaged in the three provinces of Northeast China with clear weather and no clouds are selected as the input image of atmospheric correction process. Finally, the L1-level image data is atmospherically corrected and orthorectified by the atmospheric correction algorithm based on the atmospheric radiative transfer model, obtaining the reflectance product dataset covering some black soil areas in the three northeastern provinces of China with an absolute accuracy of 7%.
