Atmospheric Science
The Atmospheric Science Research Unit of NARIT (ARUN) is a multidisciplinary research team dedicated to advancing our understanding of the complex interactions between air pollution, meteorology, and secondary organic aerosol (SOA) formation. Our group's mission is to address critical environmental and public health challenges by conducting cutting-edge research in atmospheric science.
Alongside ARUN is the Space Weather Alerts and Science (SWAS) in collaboration with Chiang Mai University’s Space Weather War Room, which is a specialized center for tracking and predicting space weather using space, ground, and underground detectors. It collects data on solar phenomena and cosmic radiation to understand their impacts on Earth.
