CORDEX_FPS_URB_RCC

• Experiment created based on the HCLIM46_develop Commits on July 18, 2025 (Commit c68d367)
• These setup are used: NPATCH=3, NHINCSOL=4, 'Dry Soil Layer' activated by default (see nam/surfex_namelists.pm).
• We still need to get in the fix for the latent heat flux, once that has been approved in NWP. See PR Hirlam/Harmonie#1203

KNMI: RACMO nested experiments

RACMO: eR2v3-v578ec-Y9909-LU2015-MAC2SP-fERA5 (1999-2009)

RACMO run on the EUR12 domain, nested in ERA5.1, restarted on 1998120100 from a simulation started in 1979.

Boundaries for HCLIM created from this experiment are stored in ECFS in ec:/rus/HXEUR12/eR2v3-v578ec-Y9909-LU2015-MAC2SP-fERA5/RACMO_HarmLBC.

RACMO: eR2v3-v578ec-Y2023-LU2015-MAC2SP-fERA5 (2020-2023)

Same as eR2v3-v578ec-Y9909-LU2015-MAC2SP-fERA5, but from different years, with many observations. Restarted on 2019120100 from a simulation started in 1979.

HCLIM46_CXURB_PARIS2p5_AROfRACMOfERA5 (1999-2009)

Modifications

• mods with fixes and extra output for TEB from Aitor's PR 193 SURFEX/TEB/GARDEN - Urban canyons
• compilation: switch from GNU to INTEL, compile with dual precision, dont't build gl_single
• Use RACMO as host model, with BDINT=1
• PARIS2.5 domain added
• Output adapted to project requirements (mainly for SURFEX/TEB) in surfex_selected_output.pm, Select_postp.pl, convertFA, yomxfu.F90 (to allow hourly min/max T)
• surfex_namelists.pm:
  • LGARDEN=.TRUE.
  • CSEA_FLUX=ECUME6
  • LSURF_MISC_BUDGET=.TRUE.
  • LUTCI=.TRUE.
• Disable abort for DIF and LSOC in init_teb_garden_pgdn.F90
• Split Archiving from Postprocessing family in climsim.tdf for speed-up
• Minor other changes:
  • Submission settings in Env_submit
  • Archiving path HM_ARC in Env_system
  • In config_exp.h (e.g. domain, hourly reset of min/max temp, FA time format & compression)
  • Archiving of logs slightly modified (archive)
