SSS sensitivity to Faraday rotation
Method : to assume a Faraday rotation angle, then select bias or noise on this angle, then simulate a regression procedure using the KleinSwift formulation.
In the Faraday angle case, since if there is an error it is likely to be the same for every data over a single satellite path, it is more adequate to speak of a bias than of a noise. When considering a bias, in order to estimate accurately the resulting bias on SSS, the measurement noise is set equal to zero. Otherwise (first 2 lines), the noise is taken to be 1 K over the T_{B}. (In such cases, the "bias" figure on SSS simply expresses the consequences of injecting random noise on the T_{B})
The following table shows the main issues.(see columns A,B,C,D,E,K;L).
