fastem()

void fastem	(	Vector &	emissivity,
		Vector &	reflectivity,
		const Numeric	frequency,
		const Numeric	za,
		const Numeric	temperature,
		const Numeric	salinity,
		const Numeric	wind_speed,
		const Numeric	transmittance,
		const Numeric	rel_azimuth,
		const Index	fastem_version
	)

Calculate the surface emissivity using FASTEM.

Calculate surface emissivity using the FASTEM model from RTTOV.

This is a direct interface to the code from RTTOV. No checkls of input is made, to obtain this feature use FastemStandAlone that is also handling multiple frequencies.

Parameters

[out]	emissivity	Calculated surface emissivity
[out]	reflectivity	Calculated surface reflectivity
[in]	frequency	Frequency [Hz]
[in]	za	Zenith angle of line-of-sigh
[in]	temperature	Temperature
[in]	salinity	Salinity [0-1]
[in]	wind_speed	Wind speed
[in]	transmittance	Transmittance along downwelling direction.
[in]	rel_azimuth	Relative azimuth angle (may not be used)
[in]	fastem_version	FASTEM version
