DBNet / DBNet information

Introduction

The sounder ATOVS aboard the NOAA/Metop satellites provides essential observational information for numerical weather prediction (NWP) to generate atmospheric analysis fields. Direct Broadcast Network (DBNet) are operational arrangements under the World Meteorological Organization to provide NWP centers with ATOVS data received at DBNet direct readout stations within 30 minutes of observation.

The DBNet monitoring pages present 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.

The KMA contribution to DBNet

The service offered by KMA to the meteorological community consisted of : Processed data from NOAA-18, NOAA-19, METOP-1 and METOP-2 from 2 sites : These sites are located at
