the Weather tile on Wear OS, the 'At a Glance' Google widget, and other services. Air quality reports are becoming increasingly more important in the United States, where climate change is contributing tolonger and harsher wildfire seasons, which often cause smoke and other particles to move ac...
Existing methods for fine-scale air quality assessment have significant gaps in their reliability. Purely data-driven methods lack any physically-based mechanisms to simulate the interactive process of air pollution, potentially leading to physically inc
In the United States, the Environmental Protection Agency (EPA) has established National Ambient Air Quality Standards (NAAQS) to protect human health and welfare. Perhaps the best introduction to large-scale ambient monitoring is to discuss each stationary site network separately. The networks have ...
