  1. Improving the Timeliness of MetOp Data Linda Stathoplos Deputy, Mission Operations Division Office of Satellite and Product Operations November 16, 2010 Image from EPS Web Site

  2. EUMETSAT Metop Antarctica Data Acquisition (ADA) Objective: • To deliver Metop data and products to users (including NOAA) with a maximum 65 minute latency • Demonstration Phase 2011-2014 will support 8 out of 14 Metop orbits • Objective fully achievable during the Operational Phase (2015)

  3. ADA Overview To improve timeliness reception of METOP Global Data Stream (GDS) data EUMETSAT plans to use McMurdo ADA for data recovery Antenna resource shared by JPSS ADA implementation will make use of a ½ orbit dumps from ADA and ½ orbit files from Svalbard (SVL) All files sent via the NOAA Darmstadt gateway GDS data is transferred to Darmstadt for processing then forwarded on to the NOAA Gateway Gateway is also used for GDS and Global Area Coverage data from SVL Dumps at ADA place data at the NOAA Gateway 45 mins earlier than present ADA data rates are expected support current pipeline processing Granules will be processed as data is received via the gateway

  4. ADA System Concept and Expected Timeliness

  5. Key Milestone Dates FOR NOAA and EUMETSAT • Submit Additional Key Questions to EUMETSAT 30 Sept 2010 • Response date from EUMETSAT 11 Oct 2010 • System Verification & Validation Readiness Review Nov 2010 • NOAA System Internal Design review 22 Nov 2010 • Initial Test data available from Lincoln Labs Nov 2010- as needed Thermal vac data processing • Metop-A downlink start (McMurdo test support) Dec 2010 • Readiness of Planning / Control in advance of data processing activities • Complete design modifications to NOAA network 30 Dec 2010 • Complete modifications to ESPC systems to accept ADA and METOP-B January 2011 • EUMETSAT ADA Integration and Verification (GS3) January 2011 • Test in-house with simulated METOP-A/B data, ½ orbit data sets January 2011 • EUMETSAT ADA Data processing Validation (GS2) Feb - April 2011 • Participate in ADA Data Proc Val. (METOP-A ADA ½ orbit test data) Feb 2011 • NOAA ADA METOP-A Readiness Review for Demo Ops Phase 1 May 2011 • Demonstration Operations Phase Start May 2011 • NOAA METOP-B Operational Readiness Review Dec 2011 • METOP-B Launch April 2012 • Full Operations Phase Start Q1 2014 5 NOAA in blue,EUMETSAT in black

  6. NOAA Preparations Thus Far Testing between NESDIS and EUMETSAT ongoing Test and verification ability to ingest ½ orbit files for processing Successfully created 1B’s from the ½ orbit files Currently supporting testing with NCEP Changes to the data stream/data file names will be limited to a new source indicator and a new spacecraft unique indicator MM will be added as a source indicator for McMurdo downlinked data SV will continue to be used for Svalbard downlinked data (1/2 orbit & full orbit) M1 will be added as a spacecraft unique id for MetOp-B M2 will continue to be used for MetOp-2 Identify in the pass/contact schedule for ADA CDA = MM Currently verifying the network bandwidth for nominal and worst case scenario for all data to/from the NOAA Gateway

  8. Processing Flow In the absence of missed dumps all data processed will achieve a timeliness of less than 65 for L1 ’ Required Link Capacity: SVL ADA Total: 8 Mbit/s 4 Mbit/s numbers below indicate the achievable timeliness for L1 PDUs processed at a point in time Dump Dump Dump Dump Dump Dump Dump over over over over over over over SVL ADA SVL ADA SVL ADA SVL Sensing Period Orbit N Orbit N+1 Orbit N+2 Acquired by SVL ? 65 ’ 50 ’ 65 ’ 65 ’ 50 ’ 115 ’ 100 ’ 85 ’ 75 ’ 50 ’ Time of 2 half of N - 1 1 half of N 2 ½ of N 1 half of N+1 2nd ½ of N+1 1 half of N+2 nd st nd st st processing (SVL) (ADA) (SVL) (SVL) (SVL) (ADA) on GS: Sensing Period Acquired by ADA ?
