ASIA-PACIFIC RARS DEVELOPMENTS (Regional ATOVS Retransmission System)Gary Weymouth8th Meeting of APSDEU, Montreal, Canada, 8-10 October 2007
The NOAA-16 ATOVS data had been received and processed for the purpose of test and research from 2001 to 2004
From 2004 to 2005, NOAA ATOVS data have been used for daily forecast and numerical weather prediction model operationally
It was discussed at APSDEU-6 that ATOVS data would be exchange in Asia-Pacific area
It was decided that Tokyo and beijing would be the intra-regional data centers
KMA finished to produce ATOVS BUFR data to be exchanged with JMA by August 2006
Routine exchange between Seoul and Tokyo is performed since 20 September 2006
Exchange of ATOVS BUFR data between KMA and JMA
- ATOVS AAPP L1C (HIRS, AMSU-A, AMSU-B, MHS)
- Telecommunication : GTS between Seoul and Tokyo at a speed of 16kbps
- Data from Seoul to Tokyo : 1 HRPT station (Seoul)
- Data from Tokyo to Seoul : 4 HRPT station (1 Japan, 3 China)
Speeding up the production of ATOVS BUFR data by revising the data processing procedure less than 25 minutes including receiving time
ATOVS data are currently used for Numerical Weather Prediction model as well as Weather Analysis.
SATEM (satellite temperature and humidity sounding) data achieved via GTS are used operationally for Global Spectral Model of Numerical Weather Prediction also.
Exchanged ATOVS data would be used for regional NWP model to improve weather forecast
Department of Satellite in KMA will be moved to Korea Meteorological Satellite Center(KMSC), 70km South-east of Seoul by June 2008
A MetOp receiving station will be setup at KMSC by the end of 2007
- MetOp ATOVS Level 1c data will be produced by AAPP v6.4 in December 2007
Upgrade of current MESDAS-2 (including NOAA HRPT receiving system) in 2008.
Producing ATOVS data User’s guide for end users such asnumerical modelers
Developing Advance dissemination method for RARS data
- A-P HRPT data loads too much burden on the KMA-JMA GTS network
- ?Internet FTP, ?Fengyuncast
Sharing Fengyuncast dissemination plan
- Dissemination of AVHRR, MTSAT HRIT, FY-3A, Terra/Aqua, EARS data
QuikSCAT / ASCAT
MODIS Polar Wind
Geostationary Meteorological Satellite Radiance
○Satellite data assimilation plan of KMA
○ operation △ Developing; ● Possible but not received
Red: New data from EUMETSAT,Blue:Replace to EUMETSAT
Key Relevant Developments
Internal and external documentation. Version control.
Sustainability into the future.
