Hi all, I want to run aquaplanet simulations but with my own SST file, using CAM4 in CESM1.2.2, thus the aquaplanet compsets won't do for me. From this site (http://hannahlab.org/cesm-aqua-planet-mode-with-prescribed-sst/) I was able to set up a run with a global fixed SST ocean. However, the anomalies between my sensitivity tests (with meridionally symmetric forcings) did not look very symmetric, leading me to realise I still have aerosol and other atmospheric forcing files that are prescribed at modern or pre-industrial values. My question is, how does one remove or zero out all of these boundary conditions?
Numerous posts I've found touch on this topic but are not very conclusive. For example, this post suggests a method to remove aerosol forcing (https://bb.cgd.ucar.edu/node/1001892) but I believe with a previous version of CAM4 as the parameters are slightly different. I would immensely appreciate a list (even partial) of the namelists/datafiles that need changing so that my aquaplanets have truly symmetric forcing.
