W_SOIL

Single-scattering albedo of the soil particles. It characterizes the efficiency 
of an average particle to scatter and absorb light. 


MIN_W_SOIL

This parameter gives the absolut lower limit of the single-scattering albedo of the soil particles. It characterizes the efficiency 
of an average particle to scatter and absorb light. 
If a sulution guess falls out-of-bonds then the attemp will be aborted and 
a new guess attempted.


MAX_W_SOIL

This parameter gives the absolut upper limit of the single-scattering albedo of the soil particles. It characterizes the efficiency 
of an average particle to scatter and absorb light. 
If a sulution guess falls out-of-bonds then the attemp will be aborted and 
a new guess attempted.


T_W_SOIL

This parameter gives temperatur for the single-scattering albedo of the soil 
particles. It characterizes the efficiency of an average particle to scatter 
and absorb light. 
This parameter gives the range over which random guesses can be expected to 
vary at first:
    W_SOIL_NEW = T_W_SOIL * tan( PI * ran_num + PI/2 ).
As the system cools the range will constrict gradually :
	T_W_SOIL_NEW_* = T_W_SOIL_OLD_* * scale, 
scale depends of NUMTEN.

opposition surge due to shadowing). 


MIN_H_SHOE

opposition surge due to shadowing). 
If a sulution guess falls out-of-bonds then the attemp will be aborted and 
a new guess attempted.


T_H_SHOE

This parameter gives temperatur for the parameter which characterizes the soil

This parameter gives the range over which random guesses can be expected to

DEN_SOIL

Specific volume density of the soil.

a new guess attempted.


MAX_DEN_SOIL

This parameter gives the absolut upper limit of the specific volume density of the soil.
If a sulution guess falls out-of-bonds then the attemp will be aborted and 
a new guess attempted.


T_DEN_SOIL

This parameter gives temperatur for the specific volume density of the soil.
This parameter gives the range over which random guesses can be expected to 
vary at first:
    DEN_SOIL_NEW = T_DEN_SOIL * tan( PI * ran_num + PI/2 ).
As the system cools the range will constrict gradually :
	T_DEN_SOIL_NEW_* = T_DEN_SOIL_OLD_* * scale, 
scale depends of NUMTEN.


THETA

Average topographic slope angle of surface roughness at subresolution scale.


MIN_THETA

This parameter gives the absolut lower limit of the average topographic slope angle of surface roughness at subresolution scale.
If a sulution guess falls out-of-bonds then the attemp will be aborted and 
a new guess attempted.


MAX_THETA

This parameter gives the absolut upper limit of the average topographic slope angle of surface roughness at subresolution scale.
If a sulution guess falls out-of-bonds then the attemp will be aborted and 
a new guess attempted.


T_THETA

This parameter gives temperatur for the average topographic slope angle of 
surface roughness at subresolution scale.
This parameter gives the range over which random guesses can be expected to 
vary at first:
    THETA_NEW = T_THETA * tan( PI * ran_num + PI/2 ).
As the system cools the range will constrict gradually :
	T_THETA_NEW_* = T_THETA_OLD_* * scale, 
scale depends of NUMTEN.


HG1_SOIL

Parameter of the first term of the Henyey-Greenstein soil particle 
phase function.


MIN_HG1_SOIL

If a sulution guess falls out-of-bonds then the attemp will be aborted and 
a new guess attempted.


MAX_HG1_SOIL

This parameter gives the absolut upper limit of the parameter of the first term of the Henyey-Greenstein soil particle 
phase function.
If a sulution guess falls out-of-bonds then the attemp will be aborted and 
a new guess attempted.


T_HG1_SOIL

Henyey-Greenstein soil particle phase function.
This parameter gives the range over which random guesses can be expected to 
vary at first:
    HG1_SOIL_NEW = T_HG1_SOIL * tan( PI * ran_num + PI/2 ).
