Earth’s ozone layer protects us from harmful solar radiation. Human activity, including use of ozone depleting compounds like some refrigerants, led to the Antarctic ozone hole. The 1987 Montreal Protocol phased down these compounds, leading to an improved ozone layer. NASA scientists work with other researchers around the world to monitor the health of the ozone layer and the size of the Antarctic ozone hole. https://go.nasa.gov/3eojsC8 #OzoneDay | NASA’s Goddard Space Flight Center
