Copernicus Marine In Situ - Argo floats real-time currents - INSITU_GLO_UV_NRT_OBSERVATIONS_013_048. SEANOE. https://doi.org/10.17882/79041 The continuously updated version of Copernicus Argo floats realtime currents product is distributed from Copernicus Marine catalogue: - https://resources.marine.copernicus.eu/?option=com_csw&view=details&product_id=INSITU_GLO_UV_NRT_OBSERVATIONS_013_048 The Argo current product generated by Copernicus in situ TAC is derived from the original trajectory data from Argo GDAC (Global Data Assembly Center) available at: - Argo float data and metadata from Global Data Assembly Centre (Argo GDAC). SEANOE. https://doi.org/10.17882/42182 In 2021, the GDAC distributes data from more than 15,000 Argo floats. Deep ocean current is calculated from floats drift at parking depth, surface current is calculated from float surface drift. An Argo float drifts freely in the global ocean, performing regular observation cycles. An observation cycle usually spreads over 10 days :  - a surface descent to a parking depth (generally 1500 meters deep) - a 10-day drift at this parking depth - an ascent to the surface (vertical profile) - A short surface drift for data transmission The data transmitted at each cycle contain temperature, salinity observations (and additional biogeochemical parameters if applicable), positions (gps or argos), technical data. The ocean current product contains a NetCDF file for each Argo float. It is updated daily in real time by automated processes. For each cycle it contains the surface and deep current variables: - Date (time, time_qc) - Position  (latitude, longitude, position_qc) - Pressure (pres, pres_qc, representative_park_pressure for parking drift, 0 decibar for surface drift) - Current (ewct, ewct_qc, nsct, nsct_qc; the current vector is positioned and dated at the last position of the N-1 cycle) - Duration (days) of the current variable sampling (time_interval) - Grounded indicator - Positions and dates have a QC 1 (good data). Positions and dates that do not have a QC 1 are ignored. The positions are measured during the surface drift (Argos or GPS positioning). For the deep current of cycle N, we take the last good position of cycle N-1 and the first good position of cycle N. For the surface current of cycle N, we take the first and last good position of the N cycle.   CARVAL Thierry DUMONT Emile Copernicus Marine in situ TAC SEANOE https://www.seanoe.org/data/00678/79041/illustration.gif Argo float surfacing Currents ODATIS aggregation parameters and Essential Variable names 2024-09-16 geonetwork.thesaurus.external.theme.NVS.OD1 IR-ARGO Research Infrastructure 2024-07-26 geonetwork.thesaurus.local.theme.IR SNO-ARGO France National Services Observation 2024-10-04 geonetwork.thesaurus.local.theme.SNO /Observational data/in-situ Type de jeux de donnée ODATIS 2024-10-15 geonetwork.thesaurus.local.theme.type_jeux_donnee CC-BY (Creative Commons - Attribution) Copernicus in situ NRT current product user manual (PUM) 2020 Ifremer 10.13155/73192 Copernicus Marine In Situ NetCDF format manual 2020 Copernicus in situ TAC COPERNICUS MARINE IN SITU TAC DATA MANAGEMENT TEAM 10.13155/59938 Copernicus Marine In Situ TAC quality information document for near real-time waves (QUID NRT WAVES) 2019 Copernicus Marine In Situ TAC VERBRUGGE NATHALIE ETIENNE HÉLÈNE MADER JULIEN CORGNATI LORENZO MANTOVANI CARLOS REYES EMMA RUBIO ANNA 10.13155/74324 oceans -180.0 180.0 -90.0 90.0 1990 2021 NC, NETCDF https://www.seanoe.org/data/00678/79041/#81492 WWW:DOWNLOAD-1.0-link--download Quality controlled data February 2021 snapshot - 151 MB https://doi.org/10.13155/54846 WWW:LINK Quality Information Document https://doi.org/10.13155/54847 WWW:LINK Product User Manual https://doi.org/10.17882/79041 WWW:LINK-1.0-http--metadata-URL DOI of the product https://www.seanoe.org/data/00678/79041/ rel-canonical Seanoe
