View Full Version : Discussion: Measuring the Earth's Ozone ...

SUMMARY: A series of NASA satellites are measuring ozone levels in the Earth's atmosphere with such precision that they can tell where's it's naturally occurring and where it's caused by pollution. The satellites included NASA's Terra, Tropical Rainfall Measuring Mission, Earth Probe/TOMS, and the ESA's ERS-2 satellite, and they were able to record fires and lightning flashes around the world. Scientists were surprised to find that larger quantities of ozone over the tropical Atlantic were actually formed by lightning strikes and not pollution as originally though.
