Collection of BGC-Argo single synthetic profile files with improved post processed Chlorophyll-A at the global scale

On January 9, 2024, ((Sauzede et al., 2016)-[https://doi.org/10.1002/2015JC011408]) development, we have applied a specific post-processing that acts similarly to a DM adjustment to improve Chla accuracy, but unlike DM data, data produced are not fully scrutinized. This post-processing procedure aims to apply three main corrections: 1) the median of the minima for dark correction; 2) the Non-Photochemical Quenching (NPQ) correction from (Xing et al. (2018))-[https://doi.org/10.1364/OE.26.024734], based on both Photosynthetically Available Radiation (PAR) and bbp measurements; 3) the physiological correction factor of fluorescence into Chla determined from the method (of Xing et al. (2011))-[https://doi.org/10.1029/2010jc006899], based on the vertical profile of Ed(490), the downwelling irradiance at 490 nm. We applied this procedure to all the BGC-Argo fleet measuring fluorescence, including floats that are non-equipped with a radiometer. For those floats, radiometric parameters [(PAR and Ed(490)] were modelled thanks to the SOCA-light method ((Schmechtig et al., 2023)-[https://doi.org/10.13155/35385]). Schematic representation of the post-processing of Chla data used for SOCA2024 training. The dashed rectangle corresponds to the correction applied using the median of data for the entire lifetime of float estimations. For instance, dark values are corrected by applying the median of all dark values computed across all profiles of the float's lifetime. The satellite indicates where a direct ocean colour matchup is required to obtain a value. Image Reference: https://www.seanoe.org/data/00911/102324/illustrations/illustration-238.gif.
