"A Chilean friend brought to my attention an unusual eight day workshop being presented by the
University of Tarapaca in Arica, Chile, a seaport in the shadow of the Andes, one of the driest spots on
earth. The subject, "Radiacion Solar Y Sus Efectos" (Solar Radiation and Its Effects), was very
interesting, to me, and since I am acquainted with the main attraction, the internationally recognized
atmospheric scientist, Sasha Madronich, and since I can't stand being in the United States during
elections, I voted absentee, signed up and left Lalafornia.
EDIT
It was a big surprise to hear from a friend from Punta Arenas, on the Strait of Magellan, that the
president of Chile and the newly elected reformist president of Argentina had met in Santa Cruz Province
in August this year and agreed to collaborate in studying the environmental effects of ozone depletion
and global warming. They issued a statement urging all the industrialized countries to ratify the Kyoto
protocol. This highly unusual meeting did not make the news in the US. It was an even bigger surprise to hear from my friend that Chile, on its own, was setting up an integrated monitoring system to study ultraviolet radiation and its effects, from Arica to Punta Arenas along the coast, up in the mountains, and even over in Chilean Antarctica. A vast distance covering over 40° of
latitude- a huge chunk of the world.
EDIT
Another Chilean scientist presented a paper on unusually large numbers of children treated for severe
sunburns during the summertime (December-February) in Santiago, the mid latitude capital, from
1996-2001. What was unusual about this study was that no effort was made to connect the implied
increase in short wave ultraviolet B radiation with the springtime Antarctic Ozone Hole, a source of so
much anxiety in Chile and elsewhere. Some other mechanism was implied.(More on this in the next
Coastal Post!)
EDIT
I asked if they had problems with sunlight, since, even under normal conditions, snow and ice efficiently
reflect ultraviolet. "No, but Thomas got snow blindness," he said. "Was it October 6th," I asked.
"I don't know," Thomas said, "... but my eyes are still sore. It feels like there is something like sand
rubbing under the lids. He took out his thick notebook and began leafing through page after page of
incredibly small, perfectly lined, hand written entries. Surprised he said, "It was October the 6th! How did you know? Was there any warning? We were working on the shade of a mountain out of any direct sunlight." There can be no shade with Ultraviolet B. It is reflected and scattered by water, sand, snow and ice or droplets and can come directly at you from any direction. My one and only case of snow blindness happened 1990 just south of the ice field. So it's a really good thing the Chileans are setting up their own
ground based, multi disciplinarian study program, including effects. Wouldn't it be nice if the US too did
something like that too? "
