ChinaHighPM₁₀: Daily Seamless 1 km Ground-Level PM₁₀ Dataset for China (2000–Present)

<p>ChinaHighPM₁₀&nbsp;is part of a series of long-term, seamless, high-resolution, and high-quality datasets of air pollutants for China (i.e., ChinaHighAirPollutants, CHAP). It is generated from big data sources (e.g., ground-based measurements, satellite remote sensing products, atmospheric reanalysis, and model simulations) using artificial intelligence, taking into account the spatiotemporal heterogeneity of air pollution.</p> <p>Here is the big data-derived seamless (spatial coverage = 100%) daily, monthly, and yearly 1 km (i.e., D1K, M1K, and Y1K) ground-level PM₁₀&nbsp;dataset for China <strong>from 2000 to the present</strong>. This dataset exhibits high quality, with a cross-validation coefficient of determination (CV-R²) of 0.90, a root-mean-square error (RMSE) of 21.12 &micro;g m^-3, and a mean absolute error (MAE) of 11.22 &micro;g m^-3&nbsp;on a daily basis.</p> <p>If you use the ChinaHighPM₁₀ dataset in your scientific research, please cite the following reference (Wei et al., EI, 2021):</p> <ul> <li> <p>Wei, J., Li, Z., Xue, W., Sun, L., Fan, T., Liu, L., Su, T., and Cribb, M.&nbsp;<a href="https://weijing-rs.github.io/publications/Wei_et_al-EI-2021.pdf">The ChinaHighPM₁₀&nbsp;dataset: generation, validation, and spatiotemporal variations from 2015 to 2019 across China</a>.&nbsp;<em>Environment International</em>, 2021, 146, 106290. https://doi.org/10.1016/j.envint.2020.106290</p> </li> </ul> <p><strong>The data is continuously updated, and</strong></p> <p>&nbsp; &nbsp; &nbsp; &nbsp; all (including&nbsp;<strong>daily</strong>) data for the year&nbsp;<strong>2022&nbsp;</strong>is accessible at:&nbsp;<strong><a href="https://doi.org/10.5281/zenodo.10475457">ChinaHighPM10 (2022)</a></strong></p> <p>&nbsp; &nbsp; &nbsp; &nbsp; all (including&nbsp;<strong>daily</strong>) data for the year&nbsp;<strong>2023 </strong>is accessible at:&nbsp;<strong><a href="https://doi.org/10.5281/zenodo.10475457">ChinaHighPM10 (2023)</a></strong></p> <p><strong>&nbsp; &nbsp; &nbsp; &nbsp; </strong>all (including&nbsp;<strong>daily</strong>) data for the year&nbsp;<strong>2024 </strong>is accessible at:&nbsp;<strong><a href="https://doi.org/10.5281/zenodo.10475457">ChinaHighPM10 (2024)</a></strong></p> <p>&nbsp; &nbsp; &nbsp; &nbsp; more data is coming soon...</p> <p><strong>More CHAP datasets for different air pollutants are available at: <a href="https://weijing-rs.github.io/product.html">https://weijing-rs.github.io/product.html</a></strong></p>
