RFM Flags

SFC Flag: Specify Surface Characteristics

30AUG17

Enabled
Driver Table requires *SFC section (optional from RFM v4.33 onwards )
Allows rays paths which intersect (and reflect from) the surface using specified surface temperature and (optionally) emissivity.

Disabled
Only allow paths which do not intersect the surface
Ignore *SFC section.

Restrictions
Incompatible with TAB and ZEN Flags.

Notes
  1. The SFC flag is required for calculations which intersect the surface, which is really just to warn the user that this is the case. In the absence of a *SFC section in the driver table (allowed from RFM v4.33 onwards ) the surface is assumed to act as a black body at the same temperature as the base of the atmosphere.
  2. See *SFC section for further details
