Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

Air pollution—specifically PM 2.5 , ozone and NO 2 —could be to blame for up to 33 million emergency asthma attack visits to hospital a year, according to a new open-access study published in the journal Environmental Health Perspectives. 37% and 73% of ozone and PM 2.5 37% and 73% of ozone and PM 2.5

After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide. New NASA satellite images released this week demonstrate the reduction of air pollution across the US.

Both aircraft will measure ozone and a mixture of soot and PM. Other instruments on the P-3B will measure pollutants that lead to the formation of ozone such as nitrogen dioxide and formaldehyde. How does ozone, which peaks near the surface in afternoon, behave at other altitudes throughout the day?

The Afternoon Constellation, so named because it crosses the equator at approximately 1:30 PM local time every day, consists of five existing satellites in tight formation, collecting simultaneous data on aerosols, clouds, cloud ice, carbon sinks, carbon sources, ozone, particulates, and atmospheric water vapor.

A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere. The same ozone-loss processes occur each winter in the Arctic.

The researchers used tropospheric NO 2 columns retrieved from the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, which measures NO 2 throughout the atmosphere in the afternoon around the world. The variation is a reflection of regional differences such as industrial development, per capita emissions and geography.
