A new version (version 5) of debiased SMOS SSS L3 maps generated by LOCEAN/IPSL/ACRI-ST is available on CATDS CEC LOCEAN.
This fifth version of Level 3 SMOS SSS covers the period January 2010-November 2020. A correction of SMOS SSS from systematic biases uses an improved ‘de-biasing’ technique: with respect to earlier versions (see a full description of the version 2 method in Boutin et al. RSE 2018), the algorithm for computing the relative biases is unchanged, but the adjustment of the long term mean biases has been slightly updated leading to local improvements in very variable areas as well as in noisy areas (in particular high latitudes and RFI contaminated areas)
Feedbacks from users about the quality of these new products are very welcome, as they are experimental.
