It's the first space-based instrument to monitor air pollution hourly across North America and is a collaboration between our Center for Astrophysics | Harvard & Smithsonian and @nasa_langley. The instrument will detect all major air pollutants with high resolution, down to the neighborhood level. For the first time, #TEMPO will help us understand where air pollution is coming from, where it’s going and how it’s impacting our communities and nature alike so we can develop sustainable solutions for the future.」4月8日 0時00分
