Good afternoon I'm working on putting in the MACv2-SP aerosol properties in OpenIFS. This requires computing aerosol optical depth in a separate routine and sending to the radiation scheme, ecRAD. I'm reading in data…

Good afternoon I'm using OpenIFS 43r3v2 and I'd like to be able to output concentrations of greenhouse gases and aerosols. It would also be great to output aerosol optical depth for a few spectral bands. I went into yo…

Good morning I've been digging into understanding how aerosols are treated in OpenIFS 43r3v1. Some output from my NODE file is at the end of this post. My questions boil down to: 1) Is there any treatment of aerosol i…

I've noticed in some namelists I'm using the value of RVOLVSPEC changes. Looking at the code this appears to be related to the volcanic aerosol optical path. Is that correct? Thanks, R.
