Dataset on topsoil organic carbon content in cropland of Northeast China (1990, 1995, 2000, 2005, 2010, 2015, 2020)
Abstract
Using over 80,000 Landsat-5/7/8 remote sensing images and elevation data, we calculated remote sensing indices representing soil formation processes as input variables. We proposed a local strategy to address the high spatial heterogeneity of soil organic carbon in Northeast China. By integrating meta-learning and deep learning models, we mapped a dataset of topsoil organic carbon content in cropland across Northeast China at 30-meter spatial resolution (1990, 1995, 2000, 2005, 2010, 2015, and 2020).
