The long-range transport (LRT) of regional atmospheric pollutants (haze, dust, biomass burning, etc.) has a significant impact on Taiwan's air quality during certain seasons. Since January 2020, East Asia has been affected by the COVID-19 epidemic in the past three years and has changed significantly, especially in anthropogenic emissions of air pollution. There is an urgent need to clarify and grasp these extraterritorial contributions from long-range transport. If it is able to further examine and grasp these variables through scientific methods(observation, model simulations, statistics, etc.), we can not only carefully evaluate the effectiveness of air pollution control policies, but also further grasp and predict the changes of the short-term and mid-term regional atmospheric pollutants and the impact on air quality in Taiwan, and achieve an early warning. The relevant government departments can respond early and the public can also be alert and protect themselves, and. In addition, satellite remote sensing technology can be applied to regional or local spatial and temporal changes in atmospheric pollution, such as the monitoring of dust and Chinese haze, or the mastering of riverbed fugitive dust and small-scale local open burning. The recent fire-induced air pollution emergencies happened frequently, and it is important to grasp the transmission and dispersion of the smoke plume and its possible impacted area. Besides, the project also actively extends and participates in international collaboration (especially in Southeast Asian Nations) and is in line with the current international technology.
