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 A^ρ, B^ρ and C^ρ (respectively A, B and C) established for TSM retrieval from reflectances Rrs, (respectively from backscattering to absorption ratio, b_b/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= A^ρ πRrs/(1 –πRrs/C^ρ) + B^ρ
Eq 2: TSM=A (b_b/a) /(1 – (b_b/a)/C) + B

As discussed in the paper, the coefficients of calibration B^ρ (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.
