RFM Flags

HOM Flag: Homogeneous Path Calculation

26JUN18

Enabled
Perform calculations for homogeneous path conditions
Path length(s) entered via the *TAN (or *LEN) section.

Disabled
Assume path through an atmosphere containing at least two profile levels.

Restrictions
Incompatible with BFX, CLC, CRV, FLX, FOV, GEO, GRA, LAY, LEV, LOS, NAD, OBS, and ZEN Flags.

Notes
  1. The path conditions are specified in the *ATM section in the normal way except that the first .atm file must contain only contain a single-level 'profile' (or just a single *HGT value).
  2. The actual value of the *HGT 'altitude' is only relevant if subsequent .atm files contain full profiles, in which case the values will be interpolated at the specified altitude. So, for example, *HGT = 10km can be used to select path conditions appropriate to 10km altitude from the profile.
  3. The SFC flag and *SFC section can be used to set any background emission.
