2 EUMETSAT Advanced Retransmission Service (EARS) Objective To provide Users with high timeliness regional data from Polar Orbiting Meteorological Satellites in support of Numerical Weather Prediction (NWP) and Nowcasting (NWC). Principle Achieved through a network of Direct Broadcast stations receiving, processing and distributing data to Users in near real time. 2 EUM/SEP/VWG/16/ Version 20 September 2016

11 Extending EARS-VIIRS with the Day/Night Band (1/3) The EARS-VIIRS Service is currently providing the 16 VIIRS Moderate resolution channels (M-Band). In response to user request, new extension implemented to include VIIRS Day/Night Band. The natural data rate of the VIIRS Day/Night Band SDR is 16 Mb/s, which is considered prohibitive for establishing such service. Data rate reduced by a combination of: Storing geolocation data on Tie-Point grid only as for VIIRS M-Band Service (CVIIRS tool); Storing Radiance using a tailored HDF5 Floating Point representation: 12 bits Mantissa Size of Exponent chosen dynamically depending on the actual range of radiance values in each granule 1 bit Sign Applying standard compression. 11 EUM/SEP/VWG/16/ Version 20 September 2016

13 Extending EARS-VIIRS with the Day/Night Band (3/3) Other activities: New features needed to be added to the Compact VIIRS SDR product format in order to support the VIIRS DNB. CVIIRS tool extended to permit users to reconstruct original VIIRS Day/Night Band SDR The VIIRS Day/Night Band included in the EARS-VIIRS service since June See of Japan - Day/Night Band image, taken 18:09 UTC 7 January EUM/SEP/VWG/16/ Version 20 September 2016

16 New EARS FY-3 Service (3/3) EARS-VASS services based on FY-3C running since February 2016 (MWHS-2 and IRAS) Coverage extended after close cooperation with CMA In addition to EUMETCast, data are also disseminated via the GTS Addition of MWRI now possible with extra software from CMA For FY-3D it is also planned to add MERSI-2 imager data 16 EUM/SEP/VWG/16/ Version 20 September 2016

17 Addition of Russian stations Metop and POES data are acquired via Moscow S-NPP data are also available from Dolgoprovny (near Moscow) since April 2016 ATOVS and IASI from Novosibirsk added in August 2016 ATOVS from Khabarovsk added today (first pass NOAA-19, 06:05Z 20/09/2016), and IASI later 17 EUM/SEP/VWG/16/ Version 20 September 2016

20 Roadmap EARS in (EPS, EPS-SG, FY-3, JPSS, Meteor, based regional services) EARS is now an operational, multimission system providing services (formally approved till 2020). We need to design and implement the successor /continuation system, being adapted to the increased number of satellites, services to be supported, new instruments, higher demands in therms of timeliness and/or availability,. We also need to consolidate the approach with partners for station services provision,. This has started with a capacity analysis of regional network in the context of future satellite availabilty and convergence with EPS-SG operations will lead to a new generation EARS EARS in the era needs to be defined and agreed by Delegate Bodies (in ) and start being implemented in (ready for EPS-SG and before end of current apporved services -2020) 20 EUM/SEP/VWG/16/ Version 20 September 2016
