NASA scientists report the ozone hole over Antarctica reached an annual maximum size of on Septem The Antarctic ozone hole is caused by manmade ozone-depleting chemicals and has been a feature of the atmosphere for more than 3 decades. Ozone protects the Earth's surface from harmful ultraviolet (UV) radiation from the sun. The UV index is a measure of the level of UV radiation.

A numerical experiment has been carried out with IAP (Institute of Atmospheric Physics) 9-layer general circulation model to investigate the influence of the Antarctic Ozone Hole on the global climate. The results show that the changes of total amount of ozone over higher latitude and polar region of the Southern Hemisphere affect not only the climate in the Southern Hemisphere, but also that Cited by: 5. Single celled marine plants (phytoplankton) are instrumental in determining global climate. They moderate the global greenhouse effect by absorbing CO 2 from the atmosphere and they release sulphur compounds, which when vented to the atmosphere, promote cloud formation and increase global reflectance of the Sun's rays. Phytoplankton proliferate in Antarctic coastal waters during spring and.
The Antarctic Ozone Hole and Ozone Science Summary: Final Report | 1 1 OMI – TOMS data used in this report Data from the Ozone Monitoring Instrument (OMI) on board the Earth Observing Satellite (EOS) Aura, that have been processed with the NASA TOMS Version algorithm, were utilized again for the weekly ozone hole reports in There were various issues that had to be hammered out, or avoided among the nations. Thus, in September , before the Airborne Antarctic Ozone Experiment was over, the diplo- matic process reached agreement on the Mon- treal Protocol, which called for cutting CFC pro- duction 50% by the year A total of 43 nations signed the by:

National Aeronautics and Space Administration.]. The Airborne Antarctic Ozone Campaign succeeded in making 12 flights of the high altitude ER-2 aircraft, and 13 flights of the DC-8 medium altitude aircraft over Antarctica. The ER-2 typically operated at geometric altitudes relative to sea level between and km and flew to 72 degrees South along the Palmer Peninsula.
Where: Punta Arenas, Chile based operations When: August - September What: A major airborne campaign studied the sudden and unanticipated decrease observed in the abundance of ozone over Antarctica in the Austral spring since Specially instrumented NASA ER-2 and DC-8 aircraft were used to acquire a database on the chemical, meteorological and cloud-physical parameters associated.
AIRBORNE ANTARTIC OZONE EXPERIMENT: To help improve our understanding of the processes which are causing Antarctic ozone to decrease, NASA is planning a two-aircraft experiment in order to obtain a data set that can be used to address the probable causes for the phenomenon.
The aircraft experiment has been designed to test many of the key. Those involved in this Airborne Antarctic Ozone Experiment say the experiment will help identify the causes of the dramatic loss of ozone in the stratosphere above Antarctica--an event that has recurred each Antarctic springtime since the mid s (SN: 5/23/87, p.
Program of CSD have a long history of conducting field and theoretical research that makes use of data gathered by instruments aboard the NASA ER-2 stratospheric research aircraft. Inthe Airborne Antarctic Ozone Experiment (AAOE) gave the first clear evidence of exactly how the chemistry of the Antarctic stratosphere is.

This chapter will provide a brief historical perspective of the Antarctic ozone hole and the role that – ground-based and aircraft studies played in linking its formation to reactions involving chlorine and bromine radicals resulting from the degradation of halocarbon source gases (emitted in large part from human activities).Author: Michael J.

“The ozone hole over the Antarctic is gradually filling up,” Haigh says. “So, it is getting a little bit less severe. So, that's the good news and the atmosphere responded as we expected. The antarctic ozone hole is an area of the antarctic stratosphere in which the recent (since about ) ozone levels have dropped to as low as 33% of their pre values.
The ozone hole occurs during the antarctic spring, from September to early December, as strong westerly wind start to circulate around the continent and create an. A reappraisal of the satellite-borne instrumentality used for the entire ozone and ozone perpendicular profile ticker is presented.
The rule of the experimental method for the monitoring of the atmospheric ozone content is used to group the basic orbiter systems. Along these lines the direct-absorption, dispersing and emission-measuring instruments are presented, giving.
Global ozone depletion and the Antarctic ozone hole Article (PDF Available) in Journal of Geophysical Research Atmospheres 97(D8) January with 97 Reads How we measure 'reads'. Monthly mean total ozone data from Syowa (69°S, 40°E), Antarctica, for show ozone to have been decreasing in October months, particularly after about Antarctic Ozone Hole The yearly depletion of stratospheric ozone over Antarctica – more commonly referred to as the “ozone hole” – started in early August and is now expanding toward its annual maximum.
Scientists have calculated that if the ozone layer was brought down to sea level it would be 3 mm thick, while in the Antarctic the ozone can be as low as 1 mm thick.
Ozone in the stratosphere is being depleted by a variety of human-made gases with a ‘hole’ forming over Antarctica. Recent observations by Farman et al.1 reveal remarkable depletions in the total atmospheric ozone content in Antarctica.
The observed total ozone decreased smoothly during the. While ozone can be found through the entire atmosphere, it is mostly concentrated at an altitude of about 15 miles.
This band of ozone-rich air, called the ozone layer, protects all life forms on Earth by filtering two harmful forms of ultraviolet light called UV-B and UV-C. Six months later, the ER-2 Microwave Temperature Profiler was one of 25 instruments participating in the first NASA-coordinated international airborne investigation of stratospheric ozone depletion, the Airborne Antarctic Ozone Experiment, AAOE (Punta Arenas, Chile, ).
"Analyzing the Antarctic Ozone Hole" is geared toward students in grades and is designed to be completed in two hours or less. It can be assigned directly to students, or used as a professional development activity to familiarize teachers with accessing and analyzing satellite data.The Antarctic ozone layer goes through seasonal variations, with a hole opening up in September each year.
In Octoberscientists discovered this hole had reached a new record of 20 million.The year is Nearly two-thirds of Earth’s ozone is gone—not just over the poles, but everywhere.
The infamous ozone hole over Antarctica, first discovered in the s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five : Michael Carlowicz.
