Mar 6, 2025 · View the latest status of the ozone layer over the Antarctic, with a focus on the ozone hole. Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone. Click any map image to bring up a new page with a high-resolution image.

Oct 30, 2024 · The map above shows the size and shape of the ozone hole over the South Pole on the day of its 2024 maximum extent. Moderate ozone losses (orange) are visible amid areas of more potent ozone losses (red).

The ozone hole is the region over Antarctica with total ozone of 220 Dobson Units or lower. This map shows the ozone hole on October 4, 2004. The data were acquired by the Ozone Monitoring Instrument on NASA’s Aura satellite.

4 days ago · View all of the Antarctic Hemisphere daily maps of total ozone for March 2025. Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone. Click any map image to bring up a …

Oct 30, 2024 · This map shows the size and shape of the ozone hole over the South Pole on Sept. 28, 2024, the day of its annual maximum extent, as calculated by the NASA Ozone Watch team. Scientists describe the ozone “hole” as the area in which ozone concentrations drop below the historical threshold of 220 Dobson units.

Nov 1, 2023 · This map shows the size and shape of the ozone hole over the South Pole on September 21, 2023, the day of its maximum extent as calculated by the NASA Ozone Watch team. Moderate ozone losses (orange) are visible amid widespread areas of …

The total ozone maps are based on ground-based measurements available from the World Ozone and Ultraviolet Radiation Data Centre. Preliminary near real-time data from ground-based observations were also used for the most recent maps.

Jul 26, 2023 · Plots showing the size of the ozone hole between 1979 and 2022. Each year for the past few decades during the Southern Hemisphere spring, chemical reactions involving chlorine and bromine cause ozone in the southern polar region to be destroyed rapidly and severely.

Nov 1, 2023 · This map shows the size and shape of the ozone hole over the South Pole on September 21, 2023, the day of its maximum extent, as calculated by the NASA Ozone Watch team. Moderate ozone losses (orange) are visible amid widespread areas of …

Jul 3, 2015 · This 3D map shows a 20 km x 20 km area of land and the air above it extending to an altitude of 100 km. Each floating particle represents 10 billion billion billion molecules of ozone. The area marked in orange indicates the ozone layer.
