RFM Flags

GRD Flag: Use Irregular Grid Files

24OCT17

Enabled
Driver Table requires *GRD section (From RFM v4.33 onwards *GRD section is optional)
Use irregular spectral grids, if available, for calculations, interpolating spectra to regular grid before output.
If generating look-up tables (TAB Flag) the output is also on the irregular grid.
From RFM v4.33 onwards, an irregular grid can also be constructed from the set of spectral points in the look-up tables supplied in via the *LUT section of the Driver Table so an explicit irreg.grid input file is not required.

Disabled
Use regular spectral grid for all calculations
Ignore *GRD section.
Interpolate absorption coefficient data from LUT files to regular grid before radiative transfer calculations.

Restrictions
Incompatible with WNG Flag.

Notes
  1. See *GRD section for further details
