  1. United States Antarctic ProgramUse of Direct Readout Raytheon NSF Matthew Lazzara Antarctic Meteorological Research Center * Space Science and Engineering Center University of Wisconsin-Madison

  2. Outline • Introduction • United States Antarctic Program • Infrastructure • USAP Ground Stations • Satellite Acquisition • Communications • Applications • On-site • USAP Reach-back • User Community • Future • Improved Communications • Upgraded direct readout

  3. Introduction: United States Antarctica Program (USAP) • McMurdo Station, established 1955 • Direct broadcast early ~1980s • South Pole Station, established 1956 • No direct broadcast reception • Palmer Station, established 1968 • Direct broadcast ~1989 • Other: • Summer Camps • APT users - historic • USAP Research/Icebreaking Vessels • R/V N.B. Palmer • USCG Polar Star and Polar Sea • Other nations using Direct Readout • Australia, UK, Norway (X-band?), Japan, Italy, etc.

  7. Communications • Internet • McMurdo • Unattended Satellite Earth Station (USES) or Black Island Telecommunications Facility (BITF) • T1 (x2) via Intelsat IS701 for 24 hours • South Pole • NASA South Pole TDRSS Relay • T3 via Marisat, GOES-3, TDRSS-1 for ~11 hours • Palmer • Palmer Satcom • T1 via Intelsat IS707 for 24 hours • Satellite data reach-back • Real-time: Internet via Antarctic-IDD, FTP, ADDE, etc. • Archive: Tapes - flown North…~twice a season • McMurdo Ground Station • NASA closed network (TDRSS network)

  8. On-Site Applications • McMurdo • Weather Forecasting • Satellite imagery • DCS Automatic Weather Stations • Tests of Derived Products • International TOVS Processing Package (ITPP) • Routine Product Generation • International MODIS/AIRS Processing Package (IMAPP) • MODIS Satellite Derived Winds (Atmospheric Motion Vectors) • Palmer Station • Research & Limited Nowcasting • Satellite imagery • DCS Automatic Weather Stations • Research Vessels & USCG • Sea Ice monitoring/depiction& Limited Nowcasting • Satellite imagery

  9. USAP Reach-back Applications • Use of the data back in the US: • University of Wisconsin-Madison • Antarctic Satellite Composites • Automatic Weather Station Observations • Data Collection System (DCS) • Iceberg Monitoring • Remote Weather Forecasting in Charleston, SC • See a greater part of the Antarctic • Contingency in the event of communications failure • CIMSS Polar Winds • Utilized by several numerical modeling centers • Numerical Modeling at NCAR • National Ice Center • Iceberg monitoring & Sea Ice depiction

  10. Cloud Mask (Cloud Detection) CIMSS CIMSS Cloud Top Pressure (Cloud Top Heights) Cloud Phase (Ice, Water, or Mix) CIMSS

  11. Polar Satellite Derived Winds Atmospheric Motion Vectors CIMSS

  12. USAP User Community • Primary users • McMurdo Weather forecasting (SPAWAR) • AARC • NSIDC/AMD • AMRC • CIMSS • NSF Contractor/RPSC • NIC • Researchers • Meteorological & Non-meteorological • Domestic and international • University and private sector • Public & Educational Outreach

  13. Future • Improved Communications • IPO and NSF MOA for ~10 Mb/s link • Thanks to SafetyNet • Upgrade to Palmer Direct Readout • Funding is uncertain • Acquisition of MetOp Direct Broadcast? • Unknown - To Be Determined • Planning for NPP and NPOESS
