C-RAID project is a global reprocessing of drifting buoys data and metadata.
The C-RAID dataset contains the metadata of 20.000 drifting buoys, deployed between 1979 and 2018. The data of 14.000 drifting buoys have been fully reprocessed and scientifically checked (delayed mode including comparison with ERA5). The project is continuing in 2023 to reprocess the remaining buoys data.
Context: The WMO DBCP Drifting Buoys GDAC (Ifremer, Meteo-France and Ocean-Canada ) is dedicated to improved quality control and delivery of drifting buoy of “climate quality” data for the Marine Climate Data System (MCDS).
Goal: clean-up an entire data archive for the past buoys deployed & reprocess the argos data & improve argos position quality (reprocessed with Kalman filter)
Lead: The C-RAID project is funded by Copernicus through a contract with the European Environment Agency. Contract # EEA/IDM/15/026/LOT1 (For Services supporting the European Environment Agency’s (EEA) implementation of cross-cutting activities for coordination of the in-situ component of the Copernicus Programme Services).
Stakeholders: DB-GDAC, Météo-France, EUMETNET (with its E-SURFMAR program), but also builds on NOAA AOML and JCOMMOPS expertise
Challenge: reprocess/recover 22,000 years of data and make them accessible
For whom? Copernicus Climate Change Service, Copernicus Marine Environment Monitoring Service, iQuam, ICOADS, GHRSST, ISPD, and ICDC.
