Solar cycle variations of stratospheric ozone and temperature in simulations of a coupled chemistry-climate model
Solar cycle stratospheric ozone coupled chemistry-climate model
font style='font-size:12px;'>
2008/12/4
The results from three 45-year simulations of a coupled chemistry climate model are analysed for solar cycle influences on ozone and temperature. The simulations include UV forcing at the top of the a...
