dtauc_ssalbCalc()

void dtauc_ssalbCalc	(	Workspace &	ws,
		VectorView	dtauc,
		VectorView	ssalb,
		const Agenda &	opt_prop_part_agenda,
		const Agenda &	propmat_clearsky_agenda,
		const Agenda &	spt_calc_agenda,
		ConstTensor4View	pnd_field,

		ConstTensor4View	vmr_field,
		ConstVectorView	f_mono
	)

dtauc_ssalbCalc

Calculates layer averaged cloud optical depth (dtauc) and single scattering albedo (ssalb). These variables are required as input for the DISORT subroutine

Parameters

ws	Current workspace
dtauc	optical depths for all layers
ssalb	single scattering albedos for all layers
opt_prop_part_agenda	use arts -d for docu
propmat_clearsky_agenda	use arts -d
spt_calc_agenda	use arts -d
pnd_field	use arts -d
t_field	use arts -d
z_field	use arts -d
p_grid	use arts -d
vmr_field	use arts -d
f_index	use arts -d

phase_functionCalc()

void phase_functionCalc	(	MatrixView	phase_function,
		const ArrayOfSingleScatteringData &	scat_data_array_mono,
		ConstTensor4View	pnd_field
	)

phase_functionCalc

Calculates layer averaged normalized phase functions from the phase matrix in SingleScatteringData. The scattering angle grid is taken from the data. It is required that all particle types include the same scattering angle grid (FIXME: Include angle interpolation)

Parameters

phase_function	normalized phase function
scat_data_array_mono	use arts -d for docu
pnd_field	use arts -d for docu

planck2()

Numeric planck2	(	const Numeric &	f,
		const Numeric &	t
	)

planck

Calculates the Planck function for a single temperature.

Comment by CE: Copied here from physics_funcs.cc, because I cannot include physics.h in m_disort.cc. The problem is that the definition of complex is not compatible with f2c.h

Note that this expression gives the intensity for both polarisations.

Returns

blackbody radiation

Parameters

f	frequency
t	temperature

pmomCalc()

void pmomCalc	(	MatrixView	pmom,
		ConstMatrixView	phase_function,
		ConstVectorView	scat_angle_grid,
		const Index	n_legendre,
		const Verbosity &	verbosity
	)

pmomCalc

Calculates Legendre polynomials of phase functions for each layer. The Legendre polynomial are required as input for DISORT.

Parameters

pmom	Legendre polynomial of phase functions
phase_function	Normalized phase function
scat_angle_grid	Scattering angle grid corresponding to phase functions
n_legendre	Number of Legendre polynomials to be calculated
