Resources for Aerosol Climatologies

[r_a_khan]

Hi,

I am running a single column simulation for CAM, in order to model variability in radiative forcing due to anthropogenic surface aerosol. In the SCAM compset, aerosol species are relaxed to the aerosol climatologies in the initial profile. I would like to get an idea of how much variability there is in these aerosol climatologies and their time series at my single column location (I am using the DycomsFR01 IOP). I am unsure however, where such data would be available, as I imagine most of these initial profiles are derived from full CAM runs. If anyone knows of resources that would be relevant, I'd really appreciate it.

The SCAM aerosol profiles are indeed monthly means from full CAM simulations that generally come off the initial conditions file.

These CAM initial files are specified in the 'use_case' for each SCAM IOP.

This file location can be found in the code tree:

bld/namelist_files/use_cases/scam*.xml

Hi Andrew,

Thank you for your response. I looked in the bld/namelist_files/use_cases/ directory, and there doesn't seem to be any entry for the dycoms_FR01 IOP. The SCAM related contents are:

scam_arm95.xml
scam_arm97.xml
scam_gateIII.xml
scam_mpace.xml
scam_sparticus.xml
scam_togaII.xml
scam_twp06.xml

This may be specific for the build that I have (cesm2.1.0 on Tetralith, NSC). I noted that all of these state that the nc_data initial condition files are located in /atm/cam/inic/gaus. Could you please let me know which file is specific for the dycoms_FR01 IOP?

Thanks,
Ramsha
