| The document describes the Quality of the Near Real Time (NRT) WAVES product delivered by the Copenicus Marine In Situ TAC. It applies to the INSITU_GLO_UV_NRT_OBSERVATIONS_013_048 product. It consists of four datasets each dedicated to near-surface currents measurements: - drifter: near-surface zonal and meridional raw velocities measured by drifting buoys, wind & wind stress components, surface temperature if available (see Table 1). These surface observations are part of the DBCP’s Global Drifter Program. - drifter_filt: near-surface zonal and meridional velocities and 3-days filtered velocities measured by drifting buoys. All the platforms are gathered together and concatenated in concatenated daily files. - radar_total: near-surface zonal and... |

| This document is the Copernicus Marine Environment Monitoring Service for In Situ observations Product User Manual (PUM) on the global currents product from drifting buoys. It describes how it is built, what is the content, what data services are available to access them, and how to use the files. The In Situ delayed mode product designed for reanalysis purposes integrates the best available version of in situ data for ocean surface currents. The data are collected from the Surface Drifter Data Assembly Centre (SD-DAC at NOAA AOML). All surface drifters data have been processed to check for drogue loss. Drogued and undrogued drifting buoy surface ocean currents are provided with a drogue presence flag as well as a wind slippage correction for undrogued... |

| The objective of this subtask is to demonstrate the value of the in-situ surface currents observing system by ensuring the link with the ESA GlobCurrent project. GlobCurrent is an ESA Data User Element started in October 2013 (running until June 2017) whose objective is “to advance the quantitative estimation of ocean surface currents from satellite sensor synergy and demonstrate impact in user-led scientific, operational and commercial applications that, in turn, will increase the uptake of satellite measurements”. In the framework of Globcurrent, several surface and near-surface current products have been calculated: global, ¼ ° maps of ocean surface geostrophic currents (from altimetry), Ekman currents at two distinct depths (surface and 15m) and... |
