Worldwide action to phase out ozone-depleting substances has resulted in remarkable success, according to a new assessment by 300 international scientists released on 10 September. The stratospheric ozone layer, a fragile shield of gas that protects Earth from harmful ultraviolet light, is on track to recovery over the next few decades. The most current ozone hole satellite data comes from the Ozone Monitoring and Profiler Suite (OMPS) instrument on the NASA-NOAA Suomi National Polar-orbiting Partnership satellite, known as Suomi NPP, and the Ozone Monitoring Instrument and Microwave Limb Sounder on NASA's Aura satellite. The full report will be available in early 2015. Suomi NPP is part of NOAA’s next generation Joint Polar Satellite System (JPSS) constellation of polar-orbiting environmental satellites. Suomi NPP, launched in October 2011, provides continuity for NASA’s Earth Observing System (EOS) and is a bridge between NOAA’s legacy Polar Orbiting Environmental S...
