This document aims to give a detailed picture of the processes and tools used to validate the dataset found in product INSITU_GLO_BGC_REP_OBSERVATIONS_013_046. This is the In-Situ Thematic Assembly Centre Re-Processed Bio-Geo-Chemical product (hereinafter BGC REP) that integrates observation aggregated from the Regional EuroGOOS consortium (Arctic-ROOS, BOOS, NOOS, IBI-ROOS, MONGOOS) and Black Sea GOOS as well as from SeaDataNet2 National Data Centers (NODCs) and EMODnet chemistry 2018 and JCOMM global systems (Argo, GOSUD, OceanSITES, GTSPP, DBCP) and the Global telecommunication system (GTS) used by the Met Offices. The BGC REP dataset integrates updated quality flags from the Near-Real Time (hereinafter NRT) product (INSITU_GLO_NRT_OBSERVATIONS_013_030) history directory files downloaded from the Global Distribution Unit at IFREMER on 2021 July 7th. Quality flags have been reanalysed in delayed mode using updated real-time and delayed mode quality assessment procedures as described in this document. The data set is a subset of the Global Ocean In-Situ Near-Real-Time Observations (INSITU_GLO_NRT_OBSERVATIONS_013_030), where the biogeochemical (chlorophyll, oxygen and nutrients (nitrate, phosphate, silicate)) parameters have been quality controlled and new quality control flags have been applied. The other parameters present in the files (and their quality control flags) are identical to the data of the original files in the data set mentioned above. Files which do not contain suitable chlorophyll, oxygen or nutrients data have not been included.
