The MACC NRT high resolution CO2 cyclic forecast (experiment g6dd) was started on 2014-08-29 to make use of a new tracer mass fixer suitable for high resolution. The experiment was initialized from the previous operational high resolution forecast g15h. Note: there were no CO2/CH4 analyses available in NRT when experiment was re-initalized.  Main features are:

  • runs in near-real-time
  • 120 h long forecast from 00UTC
  • IFS cycle 40R1
  • Coupled to CTESSEL Net Ecosystem Exchange surface fluxes.
  • EDGARv4.2 anthropogenic emissions - scaled from 2008 with estimated and climatological trends.
  • GFASv1.2 fire emissions
  • Takahashi et al. (2009) CO2 air-sea CO2 flux climatology.
  • IFS model resolution T1279L91
  • operational meteorological analysis resolution
  • time period 20140829 -
  • branch: paf_SB40R1_MACC_GHG_newmassfixer_cray_extradiag
  • New tracer mass fixer implemented based on Bermejo and Conde (2002) scheme, replacing the global proportional mass fixer used in previous operational forecast (g15h)
