ECMWF

• COPE (Continuous Observation Processing Environment) and BUFR2ODB converter use ODB API to encode/decode observation data
• Observational feedback archive uses ODB API and its data format to encode data, build index (MARS server) and (optionally) filter retrieved data on the fly (MARS client)
• ECMWF Researchers use ODB API command line tools and Python or Fortran bindings to examine observational feedback data archived by their experiments in MARS
• ODB API is used by ECMWF visualisation software, Metview and Magics, to decode and filter observational feedback data
• OBSTAT uses ODB API to compute statistics of observational feedback data

ECMWF Copernicus Department

• Copernicus Climate Change Service (C3S) uses ODB API to encode historical observational data, which is then used as input of their global reanalysis
• ODB API is also used to compute statistics of observational feedback data produced by C3S reanalysis

MetOffice and Unified Model community

• Unified Model (UM) Community, lead by the Met Office, uses ODB API as part of their Observation Processing System (OPS). UM Community includes: UK MetOffice, India Meteorological Department, Korean Meteorological Administration, Australian Bureau of Meteorology and Naval Research Laboratory.

HIRLAM

• HIRLAM community uses ODB API as part of their cooperation with ECMWF on the development of COPE system.
