Canopy_Water_Content input is unused #279
Description
The Surface structure has a member called Canopy_Water_Content (i.e. gravimetric water content of plant canopies in g/cm^3).
According to the old literature, this input should be used for example in the NESDIS_LandEM subroutine to compute MW land surface emissivity.
However, from what I can tell the input is not used.
A LUT based on the Vegetation_type input is used instead, as far as I currently understand.
The corresponding code is in NESDIS_LandEM_Module.f90.
This is not necessarily a bug, but at least somewhat unexpected code behavior.
Below is the current signature for NESDIS_LandEM:
