Monitoring of NRT Products:
NWP Model and Data Flow
This page contains improved NRT monitoring of RO data, with effect from 1st May 2017. The monitoring of data up to that point can be found at old NRT monitoring.
This page provides monitoring of near real-time (NRT) RO data. The quality of the data is monitored by comparison to forward modelled NWP model data from the Met Office and ECMWF (upgrades to these NWP systems are logged here). The following data streams are monitored:
GRAS data on Metop-A and -B, as provided by DMI and by EUMETSAT; FORMOSAT-3/COSMIC data provided by UCAR (Boulder, USA); GRACE-A and -B, TerraSAR-X and TANDEM-X data provided by GFZ (Potsdam, Germany); and GNOS data provided by CMA (Beijing, China). All of these products are available on the WMO Global Telecommunication System (GTS) - see these routing headers. Note that the 1D-Var diagnostics presented here are not calculated from the retrieval chain at DMI, but are from an offline 1D-Var run at the Met Office for quality control prior to assimilation.
We encourage feedback on this monitoring site through the ROM SAF enquiry form. Other monitoring sites are: ECMWF, Météo-France, NRL and NCEP. ECMWF also provides a Satellite Data Automatic Checking Service which includes GPSRO alerts.
