[RegCNET] Give me a hand, questions about the ctl output file.

[Yan Libin]

Dear Regcm Lovers,

I've run Regcm-dust well, but encountered some puzzles as following.

Question 1:
In domain.param file, x and y are setup as:
      parameter(iy=112)          ! number of grid points in y direction (i)
      parameter(jx=160)          ! number of grid points in x direction (j)
But in output ctl file, x and y sums up as:
xdef 529 linear 45.84 0.2252
ydef 250 linear 5.1 0.2252
Why does this happen? Are subgrids results output?

Question 2:
According to the regcm tutorial, the output file are at sigma levels.
So zdef should be between 0.0 and 1.0
But in ctl file,
zdef 18 levels 1008.68 999.55 985.85 963.02 931.06 889.96 839.73 780.37
 711.88 638.82 565.76 492.7 419.64 346.58 278.08 218.72 168.49 122.83
Do these represent the pressure of its sigma level?

Any helps will be appreciated!
