ChinaHighPM2.5: MODIS/Terra+Aqua 1 km Ground-level PM2.5 Dataset for China (Closed)

ChinaHighPM2.5 is one of the series of long-term, full-coverage, high-resolution, and high-quality datasets of ground-level air pollutants for China (i.e., ChinaHighAirPollutants, CHAP). It is generated from the big data (e.g., ground-based measurements, satellite remote sensing products, atmospheric reanalysis, and model simulations) using artificial intelligence by considering the spatiotemporal heterogeneity of air pollution. This is the MODIS/Terra+Aqua daily 1 km (D1K) ground-level PM2.5 dataset in Eastern China from 2013 to 2020, and this dataset yields a high quality with average cross-validation coefficient of determination (CV-R2) values ranging from 0.86 to 0.90, and RMSE values ranging from 10.0 to 18.4 μg/m3 on a daily basis. Note that this dataset is closed access since a longer-term (2000-2021), seamless, high-resolution (1 km), and higher quality ChinaHighPM2.5 dataset (Version 4) is available at: http://doi.org/10.5281/zenodo.3539349 More CHAP datasets of different air pollutants can be found at: https://weijing-rs.github.io/product.htmlNote that this dataset is continuously updated, and if you want to apply for more data or have any questions, please contact me (Email: weijing_rs@163.com; weijing.rs@gmail.com)
