Product user manual. For Global Ocean Reprocessed in-situ Observations of biogeochemical Product INSITU_GLO_BGC_DISCRETE_MY_013_046

This Product User Manual describes the reprocessed biogeochemical product INSITU_GLO_BGC_DISCRETE_MY_013_046 distributed by the Copernicus Marine Service (CMEMS) In Situ Thematic Assembly Centre (In SituTAC): how it is built, what is the content, what data services are available to access them, and how to use the files. The product is global and covers the period from 1st January 1993 up to real-time less eleven months, and it contains three datasets with parameters on chlorophyll-a concentration, oxygen, and nutrients (nitrate, silicate, phosphate). The In Situ TAC is a distributed system built on the existing activities and services developed within EU-funded projects and support from EuroGOOS Regional alliances. It provides a research and operational framework to develop and deliver in situ observations and derived products to address progressively global and regional needs for monitoring, modeling and downstream service development. The main objective of the Copernicus Marine Service is to deliver and operate a rigorous, robust and sustainable Ocean Monitoring and Forecasting system to users of all marine applications: maritime safety, marine resources, marine and coastal environment and climate, seasonal and weather forecasting. The In Situ TAC prepares reprocessed datasets for reanalysis activities performed by the Copernicus Marine Service forecasting centers (MFCs) and external users. The in situ reprocessed biogeochemical product integrates quality flags from the NRT multiparameter product INSITU_GLO_PHYBGCWAV_DISCRETE_MYNRT_013_030. The quality flags have been reassessed in delayed mode using updated real-time and delayed mode quality assessment procedures for the most common biogeochemical parameters, found in CMEMS-INS-QUID-013_046 (Jaccard et al., 2018) This product is designed for users that need aggregated datasets with a well-documented and transparent quality control (e.g., ocean forecasting centres, research communities, etc.). The product is published on the Copernicus Marine Service dissemination server after automatic and human quality controls. The product is available online and disseminated through the Copernicus Marine Service Information System. Files are in NetCDF format. The reprocessing system is described in the Quality Information Document (QuID): CMEMS-INS-QUID-013_046 (Jaccard et al., 2018) Information on operational issues on products and services can be found on our User Notification Service.
