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,

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

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. 3

10 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 10 NOAA-17 (NOAA- M) was launched on June 24, 2002

11 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 IJPS era began

12 IJPS Shared Partnering 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/ 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 NOAA 18 & 19 MetOp A, B & C

13 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

15 Low Data Rate Direct Readout Users NOAA Automatic Picture Transmission (APT) – Analog signal – 2 imagery channels at 4km – Frequency changed for NOAA-18 & reduce interference and MHz – NOAA 15 still active 15 Composite image courtesy of New Beith Weather Station

16 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

18 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 18
