Long Cold Spell Leads to First Arctic Ozone Hole [image] #NASA

In March 2011, the Earth Observatory published images of a rare Arctic ozone hole. The images came from daily observations made by the Ozone Monitoring Instrument on NASA’s Aura satellite. This week, a new paper in Nature uses a companion instrument on Aura, the Microwave Limb Sounder, to help describe why the ozone hole formed. The Microwave Limb Sounder (MLS) looks through the edge of Earth’s atmosphere to measure gases, in this case ozone and chlorine monoxide, one of the most dominant ozone-destroying gases. These MLS images of ozone and chlorine monoxide concentrations were made with data collected on March 18, 2011. In both cases, high concentrations of the gas are dark, while low concentrations are light. The left image shows high ozone concentrations over most of the planet, but very low concentrations—the ozone hole—over the Arctic. The right image shows chlorine ...
