Earth Sciences Monitoring Ozone Hole

October 28, 2016

Ozone Hole Monitoring 2016
The hole in Earth’s ozone layer that forms over Antarctica each September grew to about 8.9 million square miles in 2016 before starting to recover, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) who monitor the annual phenomenon. “This year we saw an ozone hole that was just below average size,” said Paul A. Newman, chief scientist for Earth Sciences at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “What we’re seeing is consistent with our expectation and our understanding of ozone depletion chemistry and stratospheric weather.” At its peak on Sept. 28, 2016, the ozone hole extended across an area nearly three times the size of the continental United States. The average area of the hole observed since 1991 has been roughly 10 million square miles. Team ADNET supports these studies at GSFC through science data analysis, processing of data from EOS Aura and Suomi NPP spacecraft, and through outreach publicizing science results.

After its orbit insertion on July 4, 2016, NASA’s Juno spacecraft performed its first close approach, or perijove, about Jupiter on August 27, passing only 2,600 miles above Jupiter’s atmosphere. The pass represents the first time all science instruments were on and recording data of the planet, including the magnetic fields instrument suite (MAG). Team ADNET staff are responsible for the creation and validation of MAG command sequences as well as the processing of engineering and science data once the telemetry hits the ground. Data from the MAG will be critical in the testing of models of Jupiter’s magnetosphere and its interaction with nearby moons. The image showing Jupiter’s north pole was taken by the JunoCam camera while still 120,000 miles away and is the first view of the pole from this angle since Pioneer 11’s flyby in 1974.
