#AcrossTheNOAAverse Take a deep breath! Today is the International Day of Clean Air. To mark the occasion we’re highlighting NOAA’s Air Resources Laboratory (ARL). ARL conducts world-class research on the chemistry and physics of the “boundary layer” of Earth’s atmosphere — that’s the area where we live and breathe. ARL’s work contributes to accurate regional and global predictions of weather and air quality, as well as climate variability. ARL also works to generate actionable information and highly localized forecasts to respond to a variety of emergencies — like wildfires, volcanoes and other high-impact air pollution episodes — more efficiently.
