LMDZ.MARS
IMPORTANT CHANGE

  • Remove all reference/use of nlayermx and dimphys.h
  • Made use of automatic arrays whenever arrays are needed with dimension nlayer
  • Remove lots of obsolete reference to dimensions.h
  • Converted iono.h and param_v4.h into corresponding modules

(with embedded subroutine to allocate arrays)
(no arrays allocated if thermosphere not used)

  • Deleted param.h and put contents into module param_v4_h
  • Adapted testphys1d, newstart, etc...
  • Made DATA arrays in param_read to be initialized by subroutine

fill_data_thermos in module param_v4_h

  • Optimized computations in paramfoto_compact (twice less dlog10 calculations)
  • Checked consistency before/after modification in debug mode
  • Checked performance is not impacted (same as before)
