The purpose of this research is to determine theinfluence of Total Ozone and Aerosols about variability of UltravioletRadiation UV in the east coast of the Northeastern region of Brazil throughmeasures from multispectral sensor GUV Ground-based Ultraviolet Radiometer.The methodology consisted of descriptive study and cluster analyses using dataof UV in channels UVB 305 nm and UVA 320 nm, 340 nm and 380 nm and data ofUV index, Total Ozone, Aerosol, Global Solar Radiation, Cloudiness and Wind.The results for city of Natal indicated that an annual event occurs inSeptember-October which stabilizes the UV or UV Index when Total Ozone levelsreach their annual maximum. This event is influenced by marine Aerosol that isfound on mainland at a higher concentration in September due to greater Windintensity and their southeasterly direction sea for land. The clusteranalysis using the variables above allowed us to detect three different groups:the first group is formed by Natal, Recife and Jo?o Pessoa and so determinedthat this event occurs in these three cities; the second group is formed byMaceió, Aracaju and Salvador and the third group includes only Fortaleza andhad different results.
