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 afternoon all I'd like to ask about a problem that's been bugging me for a few days now: Is there a way to write the O3 concentrations used by the radiation scheme to output? Some background: By default, OpenIFS u…

Hi all I'm running OpenIFS CY40R1 in a coupled configuration (with NEMOv3.6/LIM2 and OASIS3-MCT2.8). I've managed to configure updrgas to set radiation and CO2, CH4, NO2, CFC11, CFC12 to values in the CMIP5 recommended …
