IFS-COMPO CY49R1 free-running simulation of atmospheric composition (chemistry, aerosol), with meteorology re-initialized from ERA5 every day at 00UTC, with three-hourly output for the years 2003 to 2005. Spinup-time is two months (Nov-Dec 2002) and grid is reduced linear gaussian, TL255 (~80km horizontal resolution). Instantaneous aerosol MMR fields are stored on 16 pressure levels.

Examples

IFS-COMPO Reference experiment for fire emission sensitivity evaluation. This experiment uses a CY50R1 esuite model configuration, but with updates to the isoprene degradation chemistry, along with a basic implementation of C2H2 chemistry, as planned for CY51R1. Otherwise, this experiment is run as a series of 24h forecasts excluding assimilation of atmospheric composition on T511 horizontal resolution. Default GFAS fire emissions are employed here.
