Outline

• Introduction
• Current use of McIDAS/ADDE
• Applications
• Issues
• AIFS / AIFS 2
• Conclusions

3
Introduction/Role

• Support of current operational system
• Australian Integrated Forecast System (AIFS),
  including McIDAS
• 26 sites Australia wide
• Fiji Met Service, Australian Navy
• Malaysian Met Service

4
Introduction/Role

• Development of next generation system
• AIFS 2, based on
• Java/VisAD front ends
• ADDE Data Servers
• other Data Services/Event Services(eg MARS,
  Enterprise Java)

5
Current use of McIDAS

• 26 sites _at_ Mc 7.8
• 7 Regional ADDE servers
• 1 Central ADDE server (major upgrade)
• the most demanding app (CPU/mem)
• heavily batch file driven ( 1 VIF site)
• eg to produce many web pages for favourite
  products

6
Current ADDE Servers

• Primary Servers (GRID/AREA)(little use of POINT
  server)
• Secondary Servers for
• Oracle/NEONS data (Point Obs, Metars etc)
• Oracle/NEONS data (GRID NWP output)
• Radar data for ind Radar (IMAGE, Unidata)
• Archive/Mass store interface via ECMWFs MARS
  system

Applications (AMVs)

Applications (fog/low cloud)

Applications (radar overlay)

ApplicationsModis

• Miyake-jima, south of Tokyo, from Sept 2000
• The key point is that 29-32 is way more sensitive
  than 31-32, or AVHRR 4-5
• Looking forward to real time MODIS data in Darwin

11
Issues

• What are the plans for McIDAS wrt to research
  satellites (MODIS, TRMM etc) ie sec servers and
  callibration/navigation
• NetCDF support is very US centric, would be nice
  to see it more generalised (some work has been
  done on this)
• Principal Component Analysis? (CIRA, 5_at_480x640)
• IMGTRACK just select on 1st last frame please
• Units (C in IMGPROBE/BAR km/h for winds)
• Remapping problems (0.5K rounding, 8 bit only)
• GUI startup want to share files

12
AIFS

• Australian Integrated Forecast System
• Ingest, decode, storage
• Forecast/warning preparation/transmission,
  alerting, verification
• Based on McIDAS (up to 30), IDL, custom
  C/Fortran, Intranet, Oracle

13
AIFS 2

• Tools to streamline forecasting
• Model create digital forecast, store to
  forecast databasegraphics/text produced
  automatically
• More extensive verification
• 7 active Java/VisAD projects
• TC (operational), Marine (testing), Volcanic Ash,
  On Screen Analysis, IDV, Front Marker, Sounding
  Application.

Conclusion

• Support of current system. Some specialist
  development
• Focus is on the next generation
• Java/VisAD gaining acceptance (eg Volcanic Ash)
• McIDASkey role Data Service (ADDE), science and
  algorithms, link to other data services (eg MARS)
