The CAMS GHG analysis o-suite (experiment gqiq) was started on 10 June 2017 for the 20170101 cycle  based on IFS CY43R1 to enable the coupling with the new GHG forecast o-suite  (gqpe). This new suite benefits from an upgrade in the tracer mass fixer and new tagged tracers (see Diamantakis and Agusti-Panareda (2017) ECMWF Tech Memo 819. The suite runs 4 days behind real-time and caught up on 1 September 2017 and has been labelled o-suite on 1 November 2017.

Main features are:

• The suite was initialized from the GHG analysis experiment gqiq.

• The coupling with the forecast is done by merging the 4-day forecast from this analysis experiment and the cyclic high resolution forecast.

• Resolution: Tco399 (9km) and 137 vertical levels
• 5-day forecast from 00UTC
• IFS cycle 43R1
• Coupled to CTESSEL Net Ecosystem Exchange surface fluxes.
• EDGARv4.2FT2010 anthropogenic emissions - scaled from 2011 with estimated and climatological trends for CO2.
• GFASv1.2 fire emissions
• Takahashi et al. (2009) CO2 air-sea CO2 flux climatology.
• IFS model resolution Tco399L137
• time period 20170101 - current
• branch: paf_CY43R1_CAMS_GHG_esuite_an_fc
• New tracer mass fixer: Diamantakis and Agusti-Panareda (2017) with BETA value of 2.
