Is it possible to pin point exactly where the hole in the ozone layer is?

Answer 1

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. This depleted region is known as the “ozone hole”.

The area of the ozone hole is determined from a map of total column ozone. It is calculated from the area on the Earth that is enclosed by a line with a constant value of 220 Dobson Units. The value of 220 Dobson Units is chosen since total ozone values of less than 220 Dobson Units were not found in the historic observations over Antarctica prior to 1979. Also, from direct measurements over Antarctica, a column ozone level of less than 220 Dobson Units is a result of the ozone loss from chlorine and bromine compounds


Ozone is a colorless gas. Chemically, ozone is very active; it reacts readily with a great many other substances. Near the Earth’s surface, those reactions cause rubber to crack, hurt plant life, and damage people’s lung tissues. But ozone also absorbs harmful components of sunlight, known as “ultraviolet B”, or “UV-B”. High above the surface, above even the weather systems, a tenuous layer of ozone gas absorbs UV-B, protecting living things below.

The Dobson Unit (DU) is the unit of measure for total ozone. If you were to take all the ozone in a column of air stretching from the surface of the earth to space, and bring all that ozone to standard temperature (0 °Celsius) and pressure (1013.25 millibars, or one atmosphere, or “atm”), the column would be about 0.3 centimeters thick. Thus, the total ozone would be 0.3 atm-cm. To make the units easier to work with, the “Dobson Unit” is defined to be 0.001 atm-cm. Our 0.3 atm-cm would be 300 DU.

Answer 2

From the wikipedia: "A 2005 IPCC precis of ozone themes observed that observations and sort calculations propose that the worldwide known volume of ozone depletion has now approximately stabilized." it is genuinely because of the help in CFC use and using none ozone depleting components.

Answer 3

Sure, for various reasons it is over the Antarctic continent. I believe the reasons are the flow of electrons in earth's magnetic field turning back on the earth. Satellites can locate it. I am not sure why we don't hear of it also over north polar area.
This explains part of it though not why the difference

edit
Apparently because the Antarctic is colder (land instead of water)

Answer 4

no - it has depleated in general causing a drastic change in climate. people say all the time in the cold areas when it hits 50 below zero that they can't tell the ozone is depleated. this type of weather just proves the fact since the ozone is what keeps the planet warm in the colder months by blocking the release of heat. it kind of coats the planet in a stable atmosphere. it is really sad that we can't just go to one spot and fix it. people need to change their ways - eliminate gasoline engines with emissions that are doing this and also causing health problems for people and animals. sorry to ramble on. hope this helped you.

Answer 5

Pinpoint it? It's thousands of kilometres across.

Answer 6

It is known that there is a hole above Australia I believe

Answer 7

have you been on another planet ??? they've already done that....YEARS ago...
