Mars GCM:

• Improvement of the NLTE 15um scheme (for running with nltemodel = 2); now MUCH faster than previously (by a factor 5 or so):
• Improvements included to the parameterization:
  • Cool-to-space calculation included above P(atm)=1e-10, with a soft merging to the full result (without the CTS approximation) below that level
  • exhaustive cleaning of the code, including FTNCHK and reordering of loops, subroutines and internal calls
  • simplification of the precomputed tables of CO2 bands' atmospheric transmittances
  • the two internal grids (the one used in the CTS region and the one below) have been , in order to reduce the CPU time consumption
  • reading of the spectroscopic histograms is made only once, at the beginning of the GCM, to avoid repetitive readings of ASCII files
  • F90 matrix operations (matmul,...) included.
• Changes in routines:
  • removed nlte_leedat.F
  • updated nlte_calc.F, nlte_tcool.F, nlte_aux.F
  • updated nlte_commons.h, nlte_paramdef.h
  • added nlte_setup.F
• Important: The input files (in the NLTEDAT directory) read as input by these routines have changed. the NLTEDAT directory should now on contain only the following files:

deltanu26.dat enelow27.dat hid26-3.dat parametp_Tstar_IAA1204.dat
deltanu27.dat enelow28.dat hid26-4.dat parametp_VC_IAA1204.dat
