Full-coverage high-resolution (Daily, 1-km) PM2.5 dataset for China (2000-2020)

We have estimated full-coverage, daily 1-km PM2.5 data from 2000 to 2020 in China using a random forest-based hindcast modeling method which incorporates historical information into modeling. Multiple sources were used as inputs, including MAIAC AOD, meteorological data from CMA, reanalysis data from ERA-5, and other land-related data. The annual average data during 2000-2020 are released here and free for non-commercial use. This manuscript is under review.
