Resumen:
INTRODUCTORY SUMMARY.   In a global view, the ozone destruction inside the vortex has been increasing in the last decade, and it is well known that a diminishing in ozone leads to an increase in UV radiation. Nevertheless, since other factors such as solar zenith angles and clouds cover also affect the irradiances, the trends in irradiances are not so clear. Besides, when considering accumulated energies, daylength seasonal and latitudinal variations are also important. This difficulty in determining trend is even more pronounced in those places that are not under the influence of the "hole" during the whole season and, in consequence, they suffer an intermittent effect where the timing is very important in the final result. A study on the evolution of the "Ozone Hole" and its effect on irradiances for the Antarctic and Sub-Antarctic stations of the NSF UV Radiation Monitoring Network will be presented. Also, a comparison with non-affected mid latitude sites will be shown.
