WORKSPACE METHOD: refr_indexFieldAndGradients.
Calculates the field and gradients of the refractive index.
This function calculates the refractive index and its gradients for a rectangular grid.
Calculations are performed for all combinations of the given vectors, where the first vector shall contain pressure values, the second latitude values, and the last longitude values. For dimensions not used, the corresponding position vector is ignored.
The calculated values form a Tensor4, with size: <br> [atmosphere_dim+1, np, nlat, nlon] where np is the number of pressures given etc. The book of the tensor with the following index holds: <br> 0: the refractive index <br> 1: radial gradient of the refractive index <br> 2: latitude gradient of the refractive index <br> 3: longitude gradient of the refractive index
To calculate these quantities for the atmsopheric mesh, execute: <br> RefrIndexFieldAndGradients(tensor4_1,p_grid,lat_grid,lon_grid)

WORKSPACE METHOD: refr_indexIR.
Calculates the IR refractive index due to gases in the Earth's atmosphere.
Only refractivity of dry air is considered. The formula used is contributed by Michael Hoefner,bForschungszentrum Karlsruhe.
- Parameters:
-
[out] refr_index WS Output [in] rte_pressure WS Input [in] rte_temperature WS Input [in] rte_vmr_list WS Input

WORKSPACE METHOD: refr_indexThayer.
Calculates the microwave refractive index due to gases in the Earth's atmosphere.
The refractivity of dry air and water vapour is summed. All other gases are assumed ti have a negligible contribution.
The parameterisation of Thayer (Radio Science, 9, 803-807, 1974) is used. See also Eq. 3 and 5 of Solheim et al. (JGR, 104, pp. 9664).
- Parameters:
-
[out] refr_index WS Output [in] rte_pressure WS Input [in] rte_temperature WS Input [in] rte_vmr_list WS Input [in] abs_species WS Input

| void refr_indexUnit | ( | Numeric & | refr_index | ) |
WORKSPACE METHOD: refr_indexUnit.
Sets the refractive index to 1.
If this method is used, the obtained path should be identical to the geomtrical path.
As this function does not need any input, you have to include call of *Ignore* for all variables expected to be used by refr_index_agenda*.
- Parameters:
-
[out] refr_index WS Output
