The MACC NRT high resolution CO2 cyclic forecast (experiment gf39) was started on 2015-10-09 for cycle 2015010100 to replace experiment gcbt, which had issues with negative values of some of the tracers. 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)
