Solar UV irradiance measured at ground and compared with satellite TOMS/NASA derived data at different locations in Argentina
Abstract
The solar UV radiation incident on different and distant places of Argentina (Ushuaia, Puerto Madryn, Buenos Aires and Jujuy) obtained at 305, 320, 340 and 380 nm with a GUV-511/Biospherical narrowband radiometer of the CONICET Latitudinal UV-PAR radiation monitoring network, were compared with TUV model calculations in order to derive the effective aerosol optical depths in the locations indicated above. The adjusted spectral curve is employed in order to determine, -with the inclusion of the erythemal action spectrum, the corresponding integrated dose for each day. This value, usually called exposure, is compared with the data derived at noon from those taken by the satellite instrument TOMS/NASA on board of Earth Probe. Other biological UV irradiances like carcinogenesis and ADN and plant damages are also analyzed. In particular, the signals produced by the ozone hole and minihole events (with values lowers or equal to 220 DU) are clearly distinguished in the biological actions that depend strongly on the most energetic UVB radiations.
