*
*Revisions
*
* 001 J. Li (June 2006) new scheme properly account for the h2o/co2
* ratio
* 002 M. Lazare (June 2006) implement rpn fix for inpt use variable
* instead of constant in intrinsics such
* as "max" so that can compile in 32-bit mode with real*8
*
*Object
*
* Water vapor continuum for 540-800 cm-1. different from tcontl,
* variation of mass mixing ratio for h2o and co2 is consider.
* lc = 4, but the inptut data are with 6 group, 2 of them are used
* for mass mixing ratio changes
*
* taug gaseous optical depth
* qq input h2o mixing ratio for each layer
* dp air mass path for a model layer (explained in raddriv)
* dip interpolation factor for pressure between two
* neighboring standard input data pressure levels
* dir interpretation factor for mass ratio of h2o / co2 between
* two neighboring standard input ratios
* dt layer temperature - 250 k
* inptr number of the ratio level for the standard 5 ratios
* inpt number of the level for the standard input data pressures
* mcont the highest level for water vapor continuum calculation
