4 Introduction Welcome to the Central Operations Report for the first half of With this issue, our approach to reporting on the operational services has been improved to better differentiate (where possible) between the actual availability of the services from the end-user perspective and EUMETSAT s achievement against scheduled delivery, which we term operational performance. Charts depicting these two aspects have been introduced primarily for the Meteosat and Metop services, where the services concern the delivery of data and products derived from satellite systems under full EUMETSAT control. Good levels of availability were achieved for the majority of services, even with the backdrop of 5 operational incidents (see below). Gap-filling has been resumed for the Meteosat Rapid-Scanning Service (RSS) in March with the use of the backup satellite, Meteosat-8, providing continuity of imaging during the planned monthly 48-hour rest periods for the SEVIRI instrument onboard the prime RSS satellite, Meteosat-9. The operational constraint in the form of reduced antenna availability (following last November s failure of Antenna 20 in Usingen) still applied before March, and thus it was necessary to pause RSS from mid-january to mid- February, to allow the annual 28-day Full-Earth Scanning of Meteosat-9. The ADA acquisition and relay of Metop-B data has been declared operational and, on average, a high number of all half-orbit s of data are being successfully acquired and relayed to Darmstadt, providing users with Metop-B data of a vastly-improved timeliness. As mentioned above, 5 operational incidents occurred in the reporting period two of these concerned instruments on the Metop-A satellite, two concerned the EPS Ground Segment, and the remaining one concerned the MSG Ground Segment. These incidents had varying levels of impact on the operational services please see slide 9 for the Meteosat-related incident and slide 18 for the four concerning those related to Metop. Slide 4

5 Introduction (continued) Readers will notice that the Metop/NOAA Global Data Service has become the Metop-SNPP-NOAA Global Data Service. This reflects the inclusion of data from NASA-NOAA s Suomi National Polarorbiting Partnership (NPP) satellite (see further info below), following the decision of NOAA to declare SNPP fully operational and the upcoming IJPS Satellite. The following changes in content of this report are introduced in this issue: As already mentioned on the previous slide, the charts for Meteosat and Metop services now show both the availability of the service to the users and EUMETSAT s operational performance (as measured against the delivery schedules). These two metrics are explained further on slide 7. Sensor Data Records (SDRs) from the ATMS and CrIS instruments onboard NASA-NOAA s Suomi NPP satellite have been added to the Metop-NOAA Global Data Service (which now is named Metop-SNPP-NOAA Global Data Service, to reflect the new scope). The report on SDR availability has been moved from Third-Party Services to the GDS section (see slide 30). The EARS-NPP slide introduced in the last report has now been superseded by separate slides for EARS-ATMS and EARS-CrIS, in order to provide better insight into each service. See slides 33 and 36. Best regards, Livio Mastroddi Director of Operations and Services to Users Slide 5

6 Performance Reporting: Categories The charts on the following slides present a summary view of the performance of the services within the categories listed here: Meteosat Services Metop-SNPP-NOAA Global Data Service Regional Data Service (EARS) Search and Rescue Support Jason-2 OGDR Service Third-Party Data Services EUMETCast The EUMETSAT Data Centre EUMETSAT Climate Services Helpdesk Service Several terms with special meaning (e.g. Nominal RCs ) appear in the following slides. A glossary is provided at the end of the report. Slide 6

7 Performance Reporting: Conventions This report presents an overview of EUMETSAT s operational services in the half-year reporting period by means of the following two indicators: Service Availability: The availability of the operational services to users is measured monthly against the maximum amount of products/data which theoretically could be delivered each calendar month of the reporting period, i.e. from a perfect satellite system. Operational Performance: This quantifies how well EUMETSAT has performed operationally with respect to its service targets, taking into account all planned routine operational activities such as instrument calibration and spacecraft manoeuvres, i.e. the intrinsic limitations of the satellite system. These two indicators are used for Meteosat and Metop services as delivered over the prime dissemination mechanism, namely EUMETCast Europe. Where statistics are available, they are presented in the charts on the following slides. Comments are provided alongside, which identify any significant events or factors (satellite or ground-segment in nature) that have had impact on the service availability and/or operational performance. Currently, only product generation statistics are available for the Meteosat meteorological products. Note: Events having impact on more than one service (e.g. an outage of common infrastructure such as the power supply or EUMETCast) are described on a dedicated slide near the start of the service group section (i.e. Meteosat Services or Metop-SNPP-NOAA Global Data Service ). Slide 7

8 Meteosat Services This service category comprises the data and products produced with the Meteosat System, i.e. derived from geostationary satellites positioned at longitudes 0, 9.5 E and 57 E. These satellites nominally support the Full-Earth Scan (FES), Rapid-Scan (RSS) and Indian Ocean Data Coverage (IODC) services respectively. A further satellite at 3.5 E provides backup for the FES and RSS services and is used for RSS image gap-filling in the rapid-scan pauses of Meteosat-9, when operational constraints permit. The individual services addressed in this section are as follows: Meteosat Full-Earth Scan image data acquired at 0 and 57 E Meteosat Rapid Scan image data acquired at 9.5 E Meteorological products derived from that image data Data Collection and Retransmission (the DCP service) Slide 8

9 Meteosat Services: Events with General / Significant Impact The following events were of relevance with respect to the Meteosat Services: Operational Incident 59 MSG Dissemination Facility Outage 26-March-2014: Meteosat 0 service: varying degrees of interruption between 00:00 and 04:15 UTC of HRIT, LRIT and meteorological products via EUMETCast and Direct Dissemination, plus certain SAF products based on Meteosat 0 data not generated. DCP messages not relayed via EUMETCast between 01:30 and 06:20 UTC. The root cause was a software problem on the MSG dissemination facility at EUMETSAT HQ. RSS Gap-Filling: March - June Use of the backup satellite Meteosat-8 was made to provide RSS during the scheduled 48-hour gaps in scanning with Meteosat-9, which would otherwise have been present in the months March through to June. This meant effectively an increase of about 7% in the Repeat Cycles scanned and delivered to users, compared to the baseline foreseen for the Rapid-Scanning Service. Gap-filling was not possible in January and February due to operational constraints brought about by the failure of an antenna at the Usingen Ground Station in November 2013 (Operational Incident #56).

15 Metop-SNPP-NOAA Global Data Service (GDS) This service comprises the provision of Level 0, 1 and 2 products derived from Metop, S-NPP and NOAA instrument data as shown in the following table: Level 0 A-DCS AMSU ASCAT ATOVS AVHRR GOME-2 GRAS HIRS IASI MHS SEM Mx2 (1) Mx2 - ATMS & CrIS Level 1 - Mx2, N Mx2 Mx2 Mx2, N Mx2 (2) Mx2 Mx2, N Mx2 Mx2, N - SDR Level Mx2, N Mx Legend: Mx2 = Metop-A (secondary) and Metop-B (prime) - dual data & products, with the following exceptions: (1) Due to reduced capability of A-DCS on Metop-B, Metop-A provides the prime Argos-3 A-DCS service (Metop-B provides Argos-2 mode). (2) GOME-2 Tandem operations: Metop-A instrument has swath width of 960 km, Metop-B s has full width of 1920 km. N = NOAA-19 - data and products from the AMSU, AVHRR, HIRS and MHS instruments SDR = S-NPP - Sensor Data Records from the ATMS and CrIS instruments The charts on the following slides show the month-by-month availability of the products, identifying any significant events which impacted the service. Unless otherwise indicated, the availability figures are derived as shown here: For Level 0: production statistics from EUMETSAT s EPS Product Generation Facility (PGF) For Level 1: reception statistics from EUMETSAT s reference EUMETCast User Station (US) For Level 2: as for Level 1 Slide 15

16 Metop-SNPP-NOAA GDS: Definition of Availability Unless otherwise indicated in the availability slides, the monthly figures are those for timely availability, where timely is used to mean the following: Level 0 & 1: Level 2: available within 2 hours 15 minutes of sensing available within 3 hours of sensing The above timeliness targets are those originally specified for the Global Data Service and delivery is currently measured against them. The Level 0 and 1 targets are easily met since the introduction of (1) the Antarctic Data Acquisition (ADA) service which improved the timeliness of the data of the primary Metop, and (2) a multiplexed data transfer method between the Svalbard Ground Station and Darmstadt which gave a further timeliness improvement for the data of both Metops. The next slide shows the profile of Metop-B passes acquired via the ADA service, which was running in demo phase up until 2014, but is now operational and relaying half-orbits -worth of data for most of the 14 to 15 passes possible per day, delivering the first half of each orbit approximately 50 minutes earlier than that via Svalbard. On slide 19 onwards, service availability and operational performance are presented for the data (mostly delivering Level 1) from instruments on Metop-A, Metop-B, N19 and S-NPP. Please see slide 7 For explanation of the two metrics. Note: the statistics shown in the Metop-B charts on the following slides are still based on the standard timeliness criteria given above it is foreseen to apply the more demanding ADA criteria for the next issue of the report. Slide 16

17 Metop-SNPP-NOAA GDS: Antarctic Data Acquisition (ADA) Data from the primary Metop satellite (currently Metop-B) is acquired at NOAA-NSF s ground station on McMurdo Sound in Antarctica and routed to EUMETSAT HQ. This acquisition complements that of Svalbard, and allows the data of the first half of each orbit to be processed and disseminated earlier, thus improving data timeliness of Metop-based products. The chart shows the average daily passes per month that have been successfully acquired at McMurdo and relayed to Darmstadt since the system was established in early The actual daily average number of passes is 14.2, so as can be seen from the graph, we have been acquiring almost all of them since the start of ADA has now been declared operational by NOAA and EUMETSAT Monthly average of acquired passes per day Slide 17

18 Metop-SNPP-NOAA GDS: Operational Events with General/Significant Impact The following events were of relevance with respect to the Metop-SNPP-NOAA GDS: 21-Jan-2014: Operational Incident 58 - Metop-A GOME-2 Instrument Outage Metop-A GOME-2 instrument entered standby/refuse mode, resulting in a data outage of approx. 42 hours. Suspected cause was an SEU over the southern polar region. 26-March-2014: Operational Incident 60 Metop-A MHS Instrument Outage Metop-A MHS instrument unexpectedly entered fault mode at 08:40 UTC when the instrument was commanded to standby mode in preparation for an out-of-plane manoeuvre. A complex investigation followed, with the operational recovery finally achieved on 21-May, giving a total data outage of 56 days. 26-March-2014: Operational Incident 61 EPS Dissemination Facility Outage Service outage of approximately 3.5 hours for Metop-B data, and to a lesser extent, Metop-A data (because of the OOP manoeuvre described below). The root cause was a file system corruption on the EPS dissemination facility at EUMETSAT HQ. 26-March-2014: Metop-A Out-Of-Plane (OOP) Manoeuvre First Burn Product processing for the following instruments was deactivated for periods of varying length between 08:00 and 16:30 UTC: AMSU, ASCAT, ATOVS, GOME-2, GRAS, HIRS, IASI, MHS and SEM. 9-April-2014: Metop-A Out-Of-Plane (OOP) Manoeuvre Second Burn As for the first burn of the OOP manoeuvre above, but in the period 09:00 to 16:00 UTC. 2-June-2014: Operational Incident 62 - Svalbard Links Outage From 12:34 until 17:06 UTC, an outage of the underwater links to the Svalbard Ground Station impacted data from Metop-A and Metop-B, and that for EARS. The cause of the outage was attributed to a power failure on equipment at the Norwegian mainland terminal located at Harstad. Slide 18

19 Metop-SNPP-NOAA GDS A-DCS Level 0 Data Metop A & B carry instruments for supporting the Argos Advanced Data Collection System (A-DCS). Environmental data is transmitted by measurement platforms on land or sea, or in the atmosphere, and this is relayed via the Metop satellites and EUMETSAT to CLS in Toulouse, in accordance with an cooperation agreement with CNES. 98% 96% 94% 92% Metop-A Service Availability Operational Performance Target 92% Metop-A provides the prime Argos-3 A-DCS service, with Metop-B providing just Argos-2 mode, due to the reduced capability of A-DCS onboard that satellite.

21 Metop-SNPP-NOAA GDS ASCAT Level 1B (SZO & SZR) Products The Advanced Scatterometer (ASCAT) is a C-band radar on the Metop satellites which measures normalised backscatter from the Earth s surface. The prime objective of ASCAT is to measure wind speed and direction over the oceans, as an input to NWP models. ASCAT data is also used to extract information on soil moisture, sea-ice extent and permafrost boundary. EUMETSAT disseminates sampled Level 1B data from both Metop-A and Metop-B over EUMETCast and full resolution is available from the Data Centre on request. Performance of the Level 1B service is measured in terms of the timely availability of the SZO and SZR products (swath grid sampling resolutions of 25 and 12.5 km respectively) on the EUMETCast reference user station.
