OZONE LAYER HOLE IS SMALLEST IN 2019
OZONE LAYER HOLE
![]() |
2019 ozone hole smallest on record |
It is responsible for filtering out harmful ultraviolet radiation from the Sun to earth. The gas is constantly made and destroyed in the stratosphere, about 20-30 km above the Earth. it is actually as a result of warmer temperatures in the stratosphere, a layer of the atmosphere roughly seven to 25 miles above the surface of the Earth.
Due to abnormally warm temperatures in the upper atmosphere that dramatically limited ozone depletion saw in September and October this year, according to NASA and NOAA satellite measurements. however, the researchers at NASA and the National Oceanic and atmospheric administration(NOAA) cautioned that this is due to warmer atmospheric temperature and not a sign that atmospheric ozone is suddenly on a fast track to recover NASA and NOAA monitor the ozone hole via complementary instrumentals methods.
Satellites, the NASA-NOAA Suomi national polar-orbiting partnership satellite, and NOAA's joint polar satellite system NOAA-20 satellite, measure ozone from space.
