Bureau of Meteorology Update

Anthony ReaNational Manager Composite Operations

(with kind assistance from Gary Dietachmeyer, Christopher Down and Kelvin Wong)

Outline

• External environment• Operations update• NWP update• RTH Melbourne update

External Environment

• Government investment in space– Formed a Space Policy Unit in Department of

Industry, Innovation, Science and Research– Intention to formulate a Space Policy covering

multiple areas including Earth Observations from Space

• Tight budgetary position– Modest cutbacks

Direct Reception

• Geo network– Fixed antennae – Bureau-developed digital

receiver and ingestor

• L-band network– Tracking 2.4m antennae– Bureau-developed digital

receiver and ingestor

• X-band (dual-band) network– Tracking 2.4m antennae– ES&S proprietary receiver

and ingestor

Geostationary

Coverage from Bureau Receiving Stations

Direct Reception Capability and Status

• X-band network– Now in a mature phase– MODIS/AIRS product for forecasters– Real-time AIRS for NWP– Townsville X-band (AIMS)– Future plans

• L-band– COMS reception plans– MetOp reception development and plans– Consolidation of GEO reception sites in

medium term

Real-time AIRS data for NWP

• Australian contribution to IMAPP– Addition of AMSU to BUFR encoder– Excellent collaborative work by Zhihong Li

(Bureau) and Nigel Atkinson (UKMO)

• Real-time data available– 300-channel subset– BUFR format– Interoperable with global AIRS data– In real-time database now, impact experiment

will commence soon, followed by operational use

Challenges and Issues

• Data backhaul is costly– Research network AARNET used for Perth and Hobart– Internet used for Townsville– Darwin is not possible with current network capacity

• COTS Supplier– Ensuring they are ready for NPP, JPSS, Fengyun-3

and MetOp

• Internal technical expertise– Maintaining a sustainable core of satellite engineering

Melbourne RTH Update

• Improvement of MTN and regional circuits in RA V • Network migration of WMC Melbourne• WIS implementation• WIS components• WIS centres nominated in Australia• WIS Jump Start Visit• OpenWIS

ET-OI Meeting


Continued improvement on MTN and regional circuits in RA V

• WMC Melbourne joined the RMDCN IP-VPN MPLS (operated by OBS) in Nov 2009 (Potentially connected to 16 RMDCN member states, 19 ECMWF member states and 11 cooperating states, a total of 46 members)

• Melbourne is connected to MTN centres in Tokyo, Exeter and Washington on the RMDCN

• Frame Relay circuits with Singapore and Jakarta also migrated to IPVPN MPLS (operated by SingTel) in Nov 2009

• Frame Relay circuits to Nadi and Noumea remain due to the reluctance of Fiji and New Caledonia joining RA V IP-VPN
