The sounder ATOVS aboard the NOAA/Metop satellites provides essential observational information for numerical weather prediction (NWP) to generate atmospheric analysis fields. The DBNet (Direct Broadcast Network) is operational arrangement under the World Meteorological Organization to provide NWP centers with ATOVS data received at direct readout stations within 30 minutes of observation.
This page presents the operational information on JMA as a direct readout station, and outline the status of all Asia-Pacific DBNet data collected in Tokyo via the GTS regarding navigation, calibration and timeliness.
