TOP OF THE PAGE: ALERT FROM ORBIT
An expansive new view of Earth and the air we breathe
This spring, NASA, in conjunction with the Center for Astrophysics, Harvard & Smithsonian, plans to launch TEMPO, a satellite that will measure air pollution hourly across North America. It can capture data at a resolution of four square miles, a massive improvement over earlier instruments that could only focus down to 155 square miles. TEMPO (Tropospheric Emissions: Monitoring of Pollution) will conduct long-term scientific research as well as serve more immediate needs, including chemical weather forecasting and air quality alerts. Based on data from TEMPO, “we hope you’ll be able to take out your smartphone and look at an app and ask, ‘Can I run this morning?’” says project investigator Kelly Chance…
