The subpolar regions of the Southern Hemisphere are affected by short periods of low total ozonevalues directly linked to overpasses of the ozone hole. These events often happen during spring andearly summer time and the polar flames of ozone poor air travel northward to low latitudes as much asBuenos Aires (34 S). During these episodes, the subpolar regions experience a pronounced ozonereduction with generally an enhancement of UV‐B radiation, depending on cloud cover conditions. These events provoke that the sunbathing risks in human and animals increase considerably, and forthat reason the UV radiation at ground level has been considered as environmental risk in SouthAmerica. The South American Environmental Risk Network project (SAVER-Net) is an internationalproject between Argentina, Chile and Japan, below the SATREPS cooperation program. In theframework of the project we use several techniques as Differential Absorption Lidar, ozone sondesand MM-wave radiometer to measure ozone profile and total ozone column and also to makemeasurements of spectral and broadband of UV radiation at ground level. These measurements areshared with different national and international database and distributed to the public through the UVindex in web page platforms or through dedicated special dispositive (Solmaforos) that convert UVindex measurements in international codified color light that permit the easy divulgation to the publicof UV risk. In this paper we present a description of different photoprotections activities involved inthe SAVER-Net project and a revision of the ozone and UV radiation monitoring actions that are justmaking or planned in the near future.
