WMO RARS-Implementation group meeting 3-4 July 2007

• Attended by Japan, China, Korea, Argentina, EUMETSAT, Australia

• Aim for 90% coverage of globe by RARS

Some notes from WMO RARS and IGDDS Implementation Group meetings 3-6 July 2007- (WMO RARS) ‘AP-RARS Coordinator to approach relevant

HRPT operators with the objective of expanding coverage in the Central and South Pacific’

- (WMO RARS) Suggested RARS filename change (Z->W?) (BoM has changed station IDs to lower case, and ‘CPT’ to ‘mel’); Implement metadata standards(?)

- (WMO IGDDS) JMA, BoM and KMA to express their requirements for proposed additions to the FengYunCast dissemination schedule. To discuss at APSDEU-8 to obtain a consolidated regional proposal for CMA.

- Importance of installing the latest version of the AAPP software was emphasised.

APSDEU-7

• RARS has increased ATOVS real time data access and use in N Hem with major positive NWP impact

• Redundancy of RARS data an issue, however at present, data timeliness is the most important issue

• NOAA to look into RARS data from Honolulu

• metop processing – ATOVS and ASCAT

Key developments

• AP-RARS now effectively operational

• Now receiving ATOVS data from Siyowa (Japan, Antarctica)

Key Developments

• March 2007 - Singapore data successfully received in Melbourne

• April 2007 – Singapore data switched through to JMA Tokyo via GTS

• Hong Kong and New Zealand have successfully produced BUFR encoded level-1c files suitable for RARS. New Zealand data sent by FTP to The Bureau, then onto GTS.

• test data sent from Korea• NWP SAF provides QC for RARS data

Pacific data gap

• high priority to fill gap

• important stations:– Fiji (Australia to complete approx mid 2008)– Hawaii– Guam– Tahiti

New Station Summary -1Country Stations Status re Asia-Pacific RARS

Australia Casey and Davis, Antarctica, Townsville Antarctic Communications bandwidth is still an issue – not likely to be resolved in the short term due to cost. However we hope to provide RARS ATOVS data from Davis early 2008, and from Casey early 2009. Data from a new installation in Townsville should be available in mid 2009.

Canada n/a Have expressed interest in accessing Asia-Pacific region ATOVS data

Philippines Quezon City Station requires an upgrade plus AAPP

New Zealand MetService station yet to be upgraded; NIWA station operational

Metservice have agreed to contribute to RARS

Fiji Nandi – upgrade of station required and possible by early 2008

FMS is committed to contributing to RARS. Station will be upgraded in early 2008

MetOp Progress

• JMA have made significant progress in this regard, commencing MetOp-A Processing at Kiyose. Significant milestones reached have been:– Test Reception of MetOp since March 1, 2007;– Test Processing since March 16 2007;– Operational Reception and Processing since May 25

2007 using AAPP v6.3;– Upgrade to AAPP v6.4 on May 31 2007 at Kiyose and

Syowa Stations; and– Generation of data ready for AP-RARS in BUFR

format (ATOVS) since July 4 2007.

Benefits to NWP

• Significant improvements to short cut-off analyses have been demonstrated at JMA using AP-RARS data.

• Impact experiments within the Bureau’s regional and global models have also clearly demonstrated the value of timely data.

more on AP-RARS at JMA• JMA has been exchanging ATOVS data via the Global

Telecommunication System (GTS) with Australia, China, Republic of Korea and Singapore for the Asia-Pacific RARS (A-P RARS). JMA has been providing ATOVS data received at two stations, Kiyose in Japan and Syowa Station in Antarctica.

• JMA started using RARS data in its operational global data assimilation in February 2007. RARS data has positive impact on JMA’s NWP analysis and forecast.

• JMA is going to receive and provide MetOp/ATOVS data for A-P RARS in addition to NOAA/ATOVS data.

• For supporting users, JMA will open a dedicated website to provide operational information about ATOVS data received at Kiyose and Syowa Station.

• As of August 2007, ATOVS data from nine stations are available at JMA.

Brief HistoryThe 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


Current Status at KMA

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


Future Plan of KMA

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.


Propositions from KMA

Producing ATOVS data User’s guide for end users such as numerical 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

are demanding it– Additional short-term resources being brought

in to complete work

A few discussion points & plans

• pacific data gap: Fiji, Hawaii, Guam, other sites

• invite India to be involved in AP-RARS? (Fill data gap? Already run AAPP.)

• formalise testing process for RARS data? (eg new sites, installation of new versions of bufr, AAPP etc.) Avoid sending bad data for NWP assimilation.

• BoM to set up AP-RARS website 2007/8
