ChinaHighPM2.5 (Version 3)
收藏资源简介：
ChinaHighPM<sub>2.5</sub> 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 MODIS/Terra+Aqua MAIAC AOD products together with other auxiliary 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 Level 3 (L3) yearly 0.01 degree (≈ 1 km) gridded ground-level PM<sub>2.5</sub> products in Eastern China (ECHAP_PM2.5_Y1K) from 2000 to 2020, which are averaged from the Level 2 daily products. Note that the data for the year 2000 is averaged from March 2000 to December 2000. The annual PM<sub>2.5</sub> estimates are highly related to ground-based measurements (R<sup>2</sup> = 0.94) with an average root-mean-square error (RMSE) of 5.07 µg m<sup>-3</sup>. <strong>Note that this dataset is closed since a new version is published at </strong>10.5281/zenodo.3539349.
