Description (last modified by emillour)

Various problems have been identified in the current MCDv6.1 at this date:
1) negative values for solar fluxes reflected to space.
=> fixed in version 6.1.2 of the software
2) online interface maps: local time is for lon=0, regardless of map boundaries
=> more detailed info + have a dedicated extra option for users to specify if they want LT for maps to be wrt lon=0 or map center?
3) issue mentioned by Ralf Lorenz: Using the web interface, Perseverance coordinates, Mars data all, local time 13, I can plot various fields of interest, but the ‘Surface Sensible Heat Flux’ is a uniform zero… doesn’t seem right.
=> fixed in version 6.1.2 of the software
4) the pbl_parameter routine imported in MCD has been corrected since in the PCM and should be updated
=> updated in version 6.1.2 of the software
5) The RMS for winds seem to be too large compared to EOF outputs...
=> problem is in the software to compute RMS (assumed 4 outputs per sol)
6) The MCD routine computing air properties does not account for H or He...
7) MCDv6.1 software, when picking EOFs for "clim" case among non-global dust storm years, picks, them from MY24 to MY33 only... (we forgot to include MY35).
8) Some intent() in the code are wrong. Not a problem in Fortran, but does cause issues with Python interface, e.g. in subroutine LGNDR , argument X should be intent(in) and not intent(out)

Improvements: (towards MCDv6.2?)
Note that:

  • the MCDv6.1 runs were done with: nircorr=0 whereas "nircorr=1" should be used (scheme requires CO2 and O tracers to be available).
  • Now that we have an MY36 dust scenario (and soon a complete MY37) we should make the additional runs.
