Interpret profile properties as level properties (this was the default behaviour before version 1.4).  

interpret_as_level profile

 
profile can be either wc, ic or any profile type specified in profile_file.

If interpret_as_level wc is defined, a wc_file would be interpreted as follows:

	#      z     LWC    R\_eff
	#     (km)  (g/m^3) (um)
	       5.000    0      0
	       4.000   0.2   12.0
	       3.000   0.1   10.0
	       2.000   0.1    8.0
	

The value 0.2 g/m{}^{3} refers to altitude 4.0km, as e.g. in a radiosonde profile. The properties of each layer are calculated as average over the adjacent levels. E.g. the single scattering properties for the model layer between 3 and 4km are obtained by averaging over the two levels 3km and 4km. To allow easy definition of sharp cloud boundaries, clouds are only formed if both liquid water contents above and below the respective layer are larger than 0. Hence, in the above example, the layers between 2 and 3 as well as between 3 and 4km are cloudy while those between 1 and 2km and between 4 and 5km are not.

Note that since version 1.4 the default is to interpret profile properties as layer properties. For example wc properties are assumed to be constant over the layer. The layer reaches from the level, where the properties are defined in the wc_file to the level above that one. The following lines

	#      z     LWC    R_eff
	#     (km)  (g/m^3) (um)
	       4.000   0.0   0.0
	       3.000   1.0  10.0
	

define a cloud in the layer between 3 and 4 km with sharp boundaries.
