Abstract
dc.description.abstract
tropical to sub-Antarctic regions in South America. Ground
UV irradiances were measured by multichannel radiometers
as part of the Inter American Institute for Global Change
Radiation network. The irradiance channels used for this study
were centered at 305 nm (for UV-B measurements) and 340 nm
(for UV-A measurements). Results were presented as daily
maximum irradiances, as monthly averaged, daily integrated
irradiances and as the ratio of 305 nm to 340 nm. These findings
are the first to be based on a long time series of semispectral
data from the southern region of South America. As expected,
the UV-B channel and total column ozone varied with latitude.
The pattern of the UV-A channel was more complex because of
local atmospheric conditions. Total column ozone levels of ~ 2 2 0
Dobson Units were observed at all sites. Analysis of autocorrelations
showed a larger persistence of total column ozone level
than irradiance. A decreasing cross-correlation coefficient
between 305 and 340 nm and an increasing cross-correlation
coefficient between 305 nm and ozone were observed at higher
latitudes, indicating that factors such as cloud cover tend to
dominate at northern sites and that ozone levels tend to
dominate at southern sites. These results highlight the value
of long-term monitoring of radiation with multichannel radiometers to determine climatological data and evaluate the
combination of factors affecting ground UV radiation.
