Dust distribution refers to the study of how dust particles are dispersed and spread in an environment or ecosystem. This research area involves studying the sources, transport mechanisms, and deposition patterns of dust particles in a particular region or on a global scale. Dust distribution can have significant impacts on air quality, visibility, climate, and human health. Researchers use various methods such as satellite observations, ground-based measurements, and computer modeling to investigate the distribution of dust particles and their effects on the environment.
