The Asian dust source region in the Asian Dust Aerosol model version 3 (ADAM3) has been updated using the 3-hourly reporting Global Telecommunication System observation data from 1997 to 2020 at the observation stations in the Asian dust source region. The horizontal distribution of the total number of dust rise occurrence days from 1997 to 2020 has been significantly increased (decreased) at the 99% confidence level and more (less) than 14 days is used as the renewed (deleted) dust source regions. As a result, some areas of the Northern part of the Mongolia and northwest side of Gobi desert in Mongolia (North east China and Loess plateau in North China) has been added (deleted) from Asian dust source region in ADAM3. Asian dust source regions of the ADAM3 were designed based on the re-delineation through this study. The modified Asian dust source regions (EXP) were compared to the original ADAM3 (CTRL) through two Asian dust events which were observed in Korea peninsula in April 2020 and March 2021. The experiments showed that modeled dust emission is somewhat increased (reduced) by at or near the added (deleted) source regions. As a result, EXP reduced the mean absolute error and positive bias by 1.46% and 4.6% compared to CTRL. This study is expected to be the basis for research to re-delineate the Asian dust source region, consequently connecting to the improvement of dust emission modeling and forecasting in ADAM3.
