Short summary

Because of an increase in population UV exposure due to depletion of ozone, solar UV data were collected at Chilton, south England, from 1991 to 2015 and compared with ozone (O), cloudiness (C) and aerosols (A). Using multiple regression analysis, the results showed O exhibited a small increasing tendency over the same period; C played a more important role in the increasing trend in UV for 1991–2004 than O, while for 2004–2015 the decreasing trend in UV was less associated with C and A than O.
