Which satellite recorded the presence of ozone hole
Answers
Answer:NASA TOMS satellite
Explanation:
OMI continued the NASA TOMS satellite record for total ozone and other atmospheric parameters related to ozone chemistry and climate.
Answer:
Nimbus-4 satellite recorded the presence of ozone hole
Explanation:
In 1985 Jonathan Shanklin was a junior researcher at BAS when he discovered a hole in the invisible shield that protects us from solar radiation. We catch up with him to learn about his work and how it has made a difference. It's 36 years since scientists first discovered the hole in the ozone layer.
In 1986, NASA scientists used satellite data from the Total Ozone Mapping Spectrometer (TOMS) and the Solar Backscatter Ultraviolet (SBUV) instrument to demonstrate that the ozone hole is a regional-scale Antarctic phenomenon.
The ozone hole is a thinning of the protective ozone layer in the stratosphere (the upper layer of Earth's atmosphere) above Antarctica that begins every September. Chlorine and bromine derived from human-produced compounds are released from reactions on high-altitude polar clouds.
When NASA launched the Nimbus-4 satellite 50 years ago, nobody knew the ozone layer over Antarctica was thinning. And nobody knew that chlorofluorocarbons (CFCs)—long-lived chemicals that had been used in refrigerators and aerosol sprays since the 1930s—were responsible.
But the mission included a sensor called the Backscatter Ultraviolet (BUV) experiment capable of measuring ozone nonetheless. “We simply wanted to measure the atmosphere. In an interview regarding the ozone hole finding, NASA's Goddard Space Flight Center atmospheric scientist Pawan Bhartia noted, "It was curiosity-driven study.
The BUV performed well and demonstrated a new way to measure total column ozone. This led to the Total Ozone Mapping Spectrometer (TOMS) on Nimbus-7. The ozone data it collected gave researchers baseline measurements that, in the mid-1980s, helped them recognize that a troubling hole in the ozone layer had opened up.
