China's historical 1km resolution eco-environmental quality data (CHEQ)

The China's High-resolution Eco-Environmental Quality (CHEQ) dataset provides 1-km historical eco-environmental quality (EEQ) during years 2001-2019. This dataset archived in TIFF format was jointly developed by Beijing Normal University, Southern University of Science and Technology and Peking University based on multi-source remote sensing data. The dataset covers the entire land of China with a yearly temporal resolution. The existing validation results show that the CHEQ dataset was highly consistent with the environmental index (EI) provided by the Ministry of Ecology and Environment of China. The CHEQ fills the research gap in the field of EEQ monitoring in China.
