ChinaHighNO2: OMI/Aura 25 km Ground-level NO2 Dataset for China (Closed)

<p>ChinaHighNO₂&nbsp;is one of the series of long-term,&nbsp;full-coverage,&nbsp;high-resolution, and&nbsp;high-quality datasets of ground-level air pollutants for China (i.e., ChinaHighAirPollutants, CHAP). It is generated from the big data&nbsp;(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.&nbsp;</p> <p>This is the OMI/Aura-derived yearly 25 km&nbsp;ground-level O₃&nbsp;products in China&nbsp;from 2005 to 2019, and this&nbsp;dataset yields a high quality with a&nbsp;cross-validation coefficient of determination (CV-R²) of&nbsp;0.72 and&nbsp;a root-mean-square error (RMSE) of 9.97&nbsp;&micro;g m^-3&nbsp;on a daily basis.</p> <p><strong>Note that this dataset is closed access since a longer-term, seamless, high-resolution (10 km), and higher quality ChinaHighNO₂&nbsp;dataset is available at:&nbsp;<a href="https://doi.org/10.5281/zenodo.4641542">https://doi.org/10.5281/zenodo.4641542</a></strong></p> <p><strong>More CHAP datasets of different air pollutants can be found at:&nbsp;<a href="https://weijing-rs.github.io/product.html">https://weijing-rs.github.io/product.html</a></strong></p>
