  1. THORPEX Interactive Grand Global Ensemble (TIGGE) Progress on TIGGE Archive Center in CMA GONG Jiandong, SUN Jing，CHEN Jing China Meteorological Administration August 31, 2011Geneva

  2. Progress overview • 2006.07: Establish test platform • Prepare Infrastructure (LDM server, Internet connection) • Test TIGGE data receiving, from ECMWF & NCAR via LDM • Develop GRIB2 encoding and decoding software • 2006. 09: Upgrade Internet connection • Connect to CSTnet (China Science and Tech network) • Internet access rate upgraded to 100Mbps • 2006.11: Continuous data receiving test • About 8GB and 30,000 files received at CMA per day • 2007.2: Start routinely data providing and data receiving • Between CMA and ECMWF,NCAR • 2007.4: Fix the problem of losing data during the transmission between ECMWF

  3. 2007.5-8 : development of TIGGE data portal http://wisportal.cma.gov.cn/tigge/ • 2007.07-2008.12 Using MARS system • Localize and test MARS system • Test MARS local running environment • Establish MARS environment • 2008.08: Data cutting and interpolation function based on user requirement • 2008.10-2009.4：Update LDM performance • upgrade high performance LDM data receive cache • Add one 16TB SAS store disk array • Update single LDM receive to multi LDM receive • Enlarge LDM server internal memory • 2009.05：Using SMS to monitoring TIGGE data exchange

  4. 2009.05：Use MARS for data archive • All TIGGE data use MARS to archive • Link MARS to CMA TIGGE portal • 2009.07：Upgrade data Portal start to running based on MARS. • 2010.10: System upgrade • Optimal network performance, keep the intactness of received data. • Established a TIGGE Data Management System to provide data retrieval services directly for users.

  5. TIGGE Archive Platform Infrastructure and Data Processing HPC systems DATA R/D server Fire wall CMA users DATA Proc server Archive system Online data Internet users Store disks array Data Transfer Data Service Off-line data

  6. The Daily Data Reception of TIGGE

  7. (2007 - received data amount unstable. Data lost ! 2010.1: ECMWF Model resolution increased Received TIGGE DATA Amount Per Month(GB) 2008.09: CMA establish TIGGE received data intactness check. 2010.10: After network access equipment upgrade (100M  Gigabit) and network parameters tune, received data amount begin to keep stable.

  8. Data service CMA on-line monitoring and EPS comparing, 2.1TB (June 2011). China domestic users off-line data services, 45TB (June 2011). Shanghai EXPO, tropical cyclone data real-time download support. TIGGE-LAM project, CMA regional EPS data archive, 3.6G/per day. TIGGE Portal: 30 Users Website(http://wisportal.cma.gov.cn/tigge), Among them, 6 from ECMWF、JMA and Brazil Area.

  9. Continue upgrade infrastructure in future CPTEC CMA Replace 2 high-performance LDM received server LDM Server ECMWF Srv-0: CSM Server LDM Server Srv-1: LDM&GPFS FS-Manager Real-time Data receive User Search Internet Srv-2: LDM send Real-time Data receive Srv-1： MARS client Srv-3: NCL Srv-4: LDM&FTP History Data Resume Srv-2： MARS server LDM Server Srv-5: GPFS FS-Manager NCAR Data visit service LDM Server Srv-6: MARS client Share data through GPFS in Cluster CMC TIGGEportal Srv-7: MARS Svr Upgrade high-performance FC RAID (200,000 IOPS)

  10. Support to the lead centre on verification of EPS web site Upload CMA monthly statistics of GEPS verification from November 2009 up to the present; Will add the reliability table and CRPS table according to the guideline (update: July 2011) ,before the end of 2011

  11. The Updated of REPS at CMA Operational implementation Real time running. working on REPS over China working on REPS based on the WMO BO8RDP project. Jun 2011 Jun 2010 May 2009 Jan.2006 Configuration of REPS • Model(WRF-ARW dynamical core) • 15km grid space, 31 vertical levels • 60h forecast • 15 members

  12. Last WG meeting actions by CMA TIGGE data User statistics. The technique used in CMA can not meet this requirement. Adding TIGGE Data at 06/18 UTC. Done, but too big data volume, and stopped Action 8.10.2 Ms. Chen Jing discussed with GEO Secretary, no feedback.
