Dear all,

I want to run CESM model with CAM5.4 MAM4 for year after 2015, which inputdata should i use for
'ext_frc_specifier: SO2, bc_a4, num_a1, num_a2, num_a4, pom_a4, so4_a1, so4_a2'
and
'srf_emis_specifier: DMS, SO2, SOAG, bc_a4, num_a1, num_a2, num_a4, pom_a4, so4_a1, so4_a2' ?

Like num_a4, I only find ar5_mam4_num_a4_elev_1850-2005_c150205.nc at https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/cam/chem/trop_mozart_aero/emis/, which is limited on time (only till 2005). Hope someone can help me.

Thanks so much!
Best,
-Lulu

Hi Lulu,
you could use CMIP6 emissions, but the historical emissions only reach till the end of 2014. Another option could be to use future scenarios.
We do have compsets of future scenarios using CESM2, that may be a good way to start.
