Interpolate profiles assuming VMR varies linearly with altitude (or ln(p))
Disabled
Interpolate profiles assuming ln(VMR) varies linearly with altitude (or
ln(p)).

None
Notes
The main influence of this flag is when computing Curtis-Godson
equivalent parameters for each layer
The effect is only likely to be significant with molecules which vary
rapidly with altitude (eg tropospheric water vapour) and/or thick layers.
Although there is no 'correct' answer here, the default ln(vmr) interpolation
is likely to produce more physically realistic profiles in these extreme
cases.
If in doubt, just try running the RFM with/without this flag.
Aerosol extinction profiles are always interpolated linearly
since negative extinction values are permitted.
Temperature profiles (and vibrational temperatures)
are always interpolated linearly.
The interpolation with altitude or ln(p) depends on whether the user
selects a height or pressure grid at the start of the
*ATM section of the driver table.
