I am focusing on studying atmospheric aerosols, clouds, particulate matter, and trace gases using remote sensing, big data, and artificial intelligence. Up to now, I have authored over 60 SCI papers as first or corresponding authors in leading journals such as RSE, ES&T, JGR, ACP, and TGRS, including 6 ESI Hot (Top < 0.1%) papers and 11 ESI Highly Cited (Top < 1%) papers, and 7 papers have been cited more than 100 times, with the highest one of 271 times. My total citations are more than 3600 times with an H-index of 33 (Google). I was the winner of the AGU James R. Holton Award (2022) and selected to Stanford University List of the World’s Top 2% Scientists (2022, 2021). I was an Editor of Earth System Science Data and an Associate Editor of Remote Sensing. I have generated the high-resolution and high-quality datasets of ground-level air pollutants in China, the United States, and the World (i.e., CHAP, USHAP, and GHAP), which have been widely used, leading to more than 120 related publications.
