RFM Flags

LAY Flag: Automatic Sub-Layering of Profiles

18OCT18

Enabled
Halve the vertical spacing of the user-supplied profile grid.

Disabled
Use the user-supplied vertical grd

Restrictions
Incompatible with HOM Flag.

Notes
  1. The main purpose of this flag is as a quick test to see if the altitude grid-spacing on the user-supplied profiles is sufficiently fine to support the assumptions used in equating atmospheric paths to equivalent homogeneous paths for the Curtis-Godson approximation and Planck-function variation (see also BFX flag for Planck-variation). If the results with/without the LAY flag are significantly different then the layering is too coarse.
  2. If the user supplies a profile grid of N levels (specified by the first profile in the first file of the *ATM section), then this routine add an extra N-1 levels at the intermediate points, specified in altitude on ln(p), according to which type of grid is used.
  3. The PRF Flag can be used to write out the new profiles that are actually used
