Presentation Transcript

  1. NOAA’s Polar-orbiting Operational Environmental Satellites (POES) Overview Tom Schott NESDIS/OSD Satellite Product Manager U.S. Department of Commerce - NOAA NOAA Satellite Conference April 8-12, 2013

  2. Topics • Polar-orbiting Operational Environmental Satellite (POES) • Initial Joint Polar-orbiting System (IJPS)

  3. POES Mission • To provided uninterrupted flow of global environmental information in support of operational requirements for: • Global Soundings • Global Imagery • Global and Regional Surface & Hydrological Obs • Direct Readout, Data Collection, Search and Rescue • Space Environment and Ozone Observations • To establish long-term continuous data sets for climate monitoring and change predictions • Uninterrupted data requires two satellites for continuous coverage placed in orbits selected to optimize support for both weather services and climate requirements.

  4. 10am Noon 2pm 12 Z Orbit Coverage 0900Z –1500Z Afternoon POES Orbit Mid-morning MetOp Orbit

  5. 10pm Midnight 2am 00 Z Orbit Coverage 2100Z – 0300Z Afternoon POES Orbits Mid-morning MetOp Orbits

  6. Major Customers • Numerical Weather Prediction Centers • NWS National Centers for Environmental Prediction • National Weather Service Field Offices • NOAA Ocean Service and NOAA Marine Fisheries • Hazard community (Volcanic Ash Centers, US Forest Service) • Other U.S. Federal Agencies • International community • Global climate community • Direct Readout Users • High-resolution Picture Transmission (HRPT) Users • Automatic Picture Transmission (APT) Users • Search and Rescue • Data Collection System

  7. International Partners • European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) • MetOp Satellites • Canada – Department of National Defense (DND) • Search and Rescue Repeater (SARR) • France – Center National d’EtudesSpatiales (CNES) • Search and Rescue Processor (SARP) • Data Collection (DCS & A-DCS)

  8. POES Status (Apr 2, 2013)http://www.oso.noaa.gov/poesstatus/index.asp

  9. NOAA-17 Decommissioning • After nearly 11 years of service NOAA-17 will be decommissioned on April 10, 2013 • Decision based on evaluation of NOAA-17’s health, ability to provide meaningful data to the scientific and weather community, and resource demands in NESDIS/OSPO  • Since launch, the electrical power subsystem has degraded extensively, and AVHRR and AMSU-A1 instruments are no longer functional • Metop-A and B will replace NOAA-17’s data coverage NOAA-17 (NOAA-M) was launched on June 24, 2002

  10. Initial Joint Polar-orbiting System (IJPS) • IJPS consists of two independent, but fully coordinated, polar satellite systems to provide for the continuous and timely collection and exchange of environmental data from space. • Afternoon orbit provided by NOAA • NOAA-18 launched May 2005 • NOAA-19 launched Feb 2009 • Mid morning orbit provided by EUMETSAT • MetOp A launched Oct 2006 • MetOp B launched Sep 2012 • MetOp C planning launch date 2017 IJPS era began

  11. IJPS Shared Partnering MetOp A, B & C NOAA 18 & 19 • 0930 Orbit - Descending Node • Direct broadcast with • A-HRPT • Contingency Support • Data Exchange • Instruments • NOAA Provided • AVHRR/3 • HIRS/4 (not on MetOp C) • AMSU-A • SEM • SARSAT • EUMETSAT Provided • MHS • Argos (Data Collection Sys) • EUMETSAT Unique • IASI • ASCAT • GOME-2 • GRAS • 1400 Orbit -Ascending Node • Direct broadcast with existing HRPT and analog APT links • Contingency Support • Data Exchange • Instruments • NOAA Provided • AVHRR/3 • HIRS/4 • AMSU-A • SEM • SARSAT • EUMETSAT Provided • MHS • Argos (Data Collection Sys) • NOAA Unique • SBUV/2

  12. EUMETSAT MetOp-B Status • Launched on September 17, 2012 (50 minutes behind MetOp-A) • All instruments have passed cal/val and level 1b data are available through direct readout • NESDIS/OSPO/SPSD developing level 2 products from NOAA supplied instruments • Microwave Integrated Retrieval System (MIRS) Products  • April 8, 2013 at 1430 UTC  • Advanced TIROS Operational Vertical Sounder (ATOVS) Products • April 11, 2013 at 1430 UTC (rescheduled from April 1, 2013) • Scheduled for operations ~April 24, 2013 • MetOp-B will be new primary AM satellite

  13. Initial Joint Polar-orbiting System (IJPS) Svalbard, Norway Fairbanks, AK Darmstadt,Germany Polar Orbits Suitland, MD and Camp Springs, MD Wallops Is, VA NOAA 2:00 P.M. Sun-Synchronous Incl. 98.7/98.9 Period 101 min. Apogee 530/518 miles Scan width 2700 km Circle Earth 14 times per day 9:30 A.M. MetOp McMurdo

  14. Low Data Rate Direct Readout Users • NOAA Automatic Picture Transmission (APT) • Analog signal • 2 imagery channels at 4km • Frequency changed for NOAA-18 & 19 -- reduce interference • 137.1 and 137.9125 MHz • NOAA 15 still active Composite image courtesy of New Beith Weather Station http://www.newbeithweather.com/wxtoimg.php

  15. High Data Rate Direct Readout Users • NOAA High-resolution Picture Transmission (HRPT) • Realtime data at 667kbs rate • NOAA-18/19 active • MetOp Advanced High-resolution Picture Transmission (A-HRPT) • Realtime data at 3.5mbs rate • Flown on MetOp morning orbits • All instrument data including European sensors (IASI, ASCAT, etc.) • Can be encrypted

  16. Satellite Operations Contact Information

  17. Summary • NOAA continues to partner with EUMETSAT in the mid-morning polar orbit • NOAA-19 is the last of the POES satellites for the afternoon polar orbit • POES satellites have served the nation since the early 1960s • Joint Polar Satellite System (JPSS) ensures afternoon polar orbit capabilities continue
