Total suspended matter algorithm
A generic multisensor algorithm for total suspended matter retrieval in turbid waters was calibrated and validated in Nechad et al., 2010 (may be downloaded at doi:10.1016/j.rse.2009.11.022).
The coefficients Aρ, Bρ and
Cρ (respectively A, B and C) established for TSM
retrieval from reflectances Rrs, (respectively from
backscattering to absorption ratio, bb/a) to be used
in Eq 1 (respectively Eq 2),
taken at MERIS, MODIS and SeaWiFS bands or hyperspectrally
tabulated from 520nm to 885nm are listed in tables 1-2,
4-5 (respectively tables WA2-1 to WA2-6), available here.
Eq 1: TSM= Aρ πRrs/(1 –πRrs/Cρ)
Eq 2: TSM=A (bb/a) /(1 – (bb/a)/C) + B
As discussed in the paper, the coefficients of calibration Bρ (respectively B) in Eq 1 (respectively Eq 2) mostly reflects in situ measurements errors, and should be set to 0 when the algorithm is applied to a satellite images.
