South America Ozone

April 1, 2008 By Fred Johnson

The Ozone hole has
reached land and population areas in Argentina, Chile and The Falkland Islands
since the 1990’s. Ozone levels drop down as much as 70% in some areas. The
protective level of ozone has dropped below 150 dobson units in some areas. 

The area and
population affected including the Argentinean city of Ushaia which has a
population of 30,000 and Punta Arenas, Chile which has a population of 120,000
.It has reached further north at times affecting the towns of Rio Gallegos,
Puerto Santa Cruz, and Rio Grande affecting an additional 200,000 people. 

Punta Arenas is the
only city in Chile where the media provide a daily report on ultraviolet
radiation levels. When there is a yellow alert, there is a moderate level of UV
radiation, but an orange or red alert means dangerous levels.

The residents of
Punta Arenas, despite receiving more unfiltered solar radiation, are less
affected because they do not expose as much skin to the Sun’s rays. The region’s
cold temperatures mean that people are less likely to be found outside with bare
heads or arms. Another element in their favor is the location of the city with
respect to the Sun. In Punta Arenas, solar radiation reaches the Earth’s surface
at a much more acute angle – and is therefore less intense – than in Santiago,
located 2,200 km to the north.

Chile has various
ozone level measuring stations, Institutions like the Meteorological
Administration and the Universities of Chile and Magellan, carry out permanent
exploration on the state of the ozone layer.
