the CO2 of ”SCWACCM_forcing_WACCM6_zm_5day_L70_1975-2014_c180216.nc“ is time×level×lat .

I want to change CO2 from 1975-2014 to 1980-2020 ,but i can't find the datasets of CO2 (with different lat and level).

The WACCM forcing file for SC-WACCM is created from output from WACCM simulations with interactive chemistry. We created the first you see from CMIP6 AMIP simulations, which end at the end of 2014. We have not yet created such files from SSP simulations, or SD-WACCM runs that extend beyond 2014. I will discuss support for your request with our WACCM group. You will require additional forcing files to run SC-WACCM beyond 2014.

Thank you very much for your reply .
But I have no idear about the "additional forcing files" .
Does the dimension of the variable in the new file have to be the same as the original file ?
For example, how CO2 (time) data is handled as three-dimensional (time×level×lon) data .
Or somehow get new forcing files . Or change GHG's forcing in other ways .
 
On this issue, we have been using so far SCWACCM_forcing_zm_L70_1849-2015_CMIP6ensAvg_c181011.nc to run historical simulations with a cam6.3 version with 83 levels.

Now we are going to swap to the scenario compset SSP585 but we were not able to find any corresponding file.
Could you help us?
