The profile in the atmosphere_file provides the constituents of the atmosphere
at the given levels. Where additional levels are introduced and in order to calculate
layer properties, an assumption about the variation of the
property within the layer is required. These interpolation methods can be
changed by the z_interpolate option. Two arguments are required, the
property, and the interpolation method:
z_interpolate property interpolation_method
Properties which may be specified are:
- O3, O2, H2O, CO2, NO2, BRO, OCLO, HCHO
-
- T
-
temperature (here linmix is not suitable)
Possible interpolation methods are:
- linear
-
The specified property (number density of the gas or temperature) varies linearly with height.
- log
-
The specified property (number density of the gas or temperature) varies logarithmically with height.
This is a reasonable option for all well mixed trace gases.
- linmix
-
This option is only possible for gas profiles.
The mixing ratio of the gas (assuming a logarithmically varying
air density) varies linearly with height.
For all gas densities the default interpolation method is linmix,
for temperature it is linear.
