1.5 Experiments: stratospheric-ozone-only SSP2-4.5 run (ssp245-stratO3)

Record Label : ssp245-stratO3

Record Title : stratospheric-ozone-only SSP2-4.5 run

Record identifier : f16d9f60-dd9e-11e6-b89b-ac72891c3257

Description : Extension of stratospheric-ozone-only run, hist-stratO3, under SSP2-4.5 forcing to the year 2100. In models with coupled chemistry, he chemistry scheme should be turned off, and the simulated ensemble mean monthly mean 3D stratospheric ozone concentrations from the SSP2-4.5 simulations should be prescribed. Tropospheric ozone should be fixed at 3D long-term monthly mean piControl values, with a value of 100 ppbv ozone concentration in this piControl climatology used to separate the troposphere from the stratosphere. In models without coupled chemistry the same stratospheric ozone prescribed in SSP2-45 should be prescribed. Stratospheric ozone concentrations will be provided by CCMI.
