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 (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 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

12 hours of RARS AMSUB/MHS data

Pacific data gap high priority to fill gap important stations: –Fiji (Australia to complete approx mid 2008) –Hawaii –Guam –Tahiti

New Station Summary -1 CountryStationsStatus re Asia-Pacific RARS AustraliaCasey and Davis, Antarctica, TownsvilleAntarctic 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 Data from a new installation in Townsville should be available in mid Canadan/aHave expressed interest in accessing Asia-Pacific region ATOVS data PhilippinesQuezon CityStation requires an upgrade plus AAPP New ZealandMetService station yet to be upgraded; NIWA station operational Metservice have agreed to contribute to RARS FijiNandi – upgrade of station required and possible by early 2008 FMS is committed to contributing to RARS. Station will be upgraded in early 2008

Top priority satellites and instruments?

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 ; –Operational Reception and Processing since May using AAPP v6.3; –Upgrade to AAPP v6.4 on May at Kiyose and Syowa Stations; and –Generation of data ready for AP-RARS in BUFR format (ATOVS) since July

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 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.

APSDEU-8/10-12 October 2007/CMC, Canada Korea Meteorological Administration Brief History 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

APSDEU-8/10-12 October 2007/CMC, Canada Korea Meteorological Administration 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

APSDEU-8/10-12 October 2007/CMC, Canada Korea Meteorological Administration 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 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.

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
