The CAMS NRT research e-suite for CY47R2_CAMS (experiment hifh, class rd) was started on 2021-01-14 for the analysis cycle 2021010100. This e-suite  runs at T511L137. Main features (with new items in italics) are:

• 120 h long forecast from 00UTC and 12UTC
• IFS model resolution T_L511L137
• 4D-Var minimisations at T_L95 and T_L159, using 12h 4D-Var and VarBC
• 4D-Var analysis windows from 15-3UTC and 3-15UTC
• IFS-CB05-AER
• coupled ocean (NEMO) in ORCA025_Z75 configuration
• interactive ozone and aerosol in the radiation code
• CAMS_GLOB_BIO v1.0 climatological biogenic emissions
• CAMS_GLOB_ANT v4.2 anthropogenic emissions, excluding agricultural waste burning (AWB) to avoid double-counting with GFAS
  
• Volcanic outgassing emissions, based on Carn et al. (2017) - reduced for certain volcanoes based on recent observations
• Hybrid Linear Ozone (HLO) scheme for stratospheric ozone
• GFASv1.4 fire emissions (retaining cap for organic matter as in previous cycles)
  
• Cap on anthropogenic primary OM emissions
• Increased numerical precision in emission input files
• Forecast (but not analysis) running with single precision arithmetic for computational efficiency

This is the research-mode counterpart to the pre-operational e-suite 0075 under class "mc", which has forecast-only "control run" hj7b (plus a variant using climatological aerosol and ozone in radiation, hj88).

(The earlier control run hig6, and climatological counterpart hige, had a minor bug in their initialisation, and so were replaced by the above and retired at the implementation of 47r2.)
