c     aszlyt  - Soil layer thicknesses for each subregion (mm)

c              range values       min        max
c              ------------   ---------  ---------
c              fixed          0.1        ?
c              typical        1          25
c              ------------   ---------  ---------

c            - This variable maintains the soil layer thickness values
c              for each of the subregions.

c     nslay  - Number of soil layers being used for each subregion.

c              range values       min        max
c              ------------   ---------  ---------
c              fixed          1          mnsz

c              ------------   ---------  ---------

c            - This variable maintains the number of active soil layers
c              for each subregion.

c      asfcle - Linear extensibility

c              range values       min        max
