TY - Data T1 - MuAP Spatial distribution of various air pollutants in China at 1 km(PM2.5 2015-01-01:2020-12-31) (Version1.1) A1 - Ye Hong DO - 10.5281/zenodo.8093749 PY - 2025 DA - 2025-08-28 PB - National Cryosphere Desert Data Center AB - This dataset optimizes the LightGBM model by combining spatial sampling and parameter convolution, utilizing ground observation data, remote sensing products, meteorological data, auxiliary data, and random IDs. Based on the above technology and simulation of air pollutants, generate daily PM2.5 products with a resolution of 1 kilometer in most parts of China from 2015 to 2020.
