Function Documentation

get_flh()

void get_flh	(	l2str *	l2rec,
		float	flh[]
	)

get_flh - computes fluorescence line height for MODIS, MERIS, OLCI and OCI computation based on Lw measurements

Parameters

l2rec
flh

the flh algorithm requires nLw values from 667, 678 and 748nm

if the pixel is already masked, or any of the input Lw values are less than -0.01, set the PRODFAIL flag and move along

Lw,f (Behrenfeld et al.[2009] equation A2 and A3)

bias correction as per Behrenfeld et al. [2009]

Definition at line 131 of file fluorescence.c.

get_fqy()

void get_fqy	(	l2str *	l2rec,
		float	fqy[]
	)

get_fqy - function to return fluorescence quantum yield for the MODIS, MERIS, OLCI and OCI instruments internally calls the calc_fsat and get_ipar functions

Parameters

l2rec
fqy

Definition at line 239 of file fluorescence.c.

get_fsat()

void get_fsat	(	l2str *	l2rec,
		float	flh[]
	)

get_flh - computes normalized fluorescence line height for MODIS, MERIS, OLCI and OCI computation based on nLw measurements (thus the normalized moniker)

Parameters

l2rec
flh

the nflh algorithm requires nLw values from 665, 680 and 709nm

if the pixel is already masked, or any of the input nLw values are less than -0.01, set the PRODFAIL flag and move along

fsat (Behrenfeld et al.[2009] equation A2)

bias correction as per Behrenfeld et al.
