Limited flexibility RANET Various Large footprint TBD Suitable for end-user distribution, remote areas (*) «Direct Readout» because LRIT is transmitted from a meteorological satellite Findings DATA DISTRIBUTION SYSTEMS Several data distribution capabilities available in Regions III/IV but issues with - integration; - data/products available; - bandwidth; - sustainability of service. - Direct Readout an option for only few countries (Brazil, Argentina, Canada) - Ftp/internet with limited bandwidth for NRT applications - GNC-A / EUMETCast-Americas possible solutions but need (i) additional data and (ii) confirmed sustainability and operational support

Achievements : Mitigating the loss of GOES-12 NOAA/NESDIS (M. Kicza, 5 Aug 2013) letter to WMO Informed about decommissioning of GOES-12; Asked RA-3-4-SDR to collaborate on planned GOES-13 optimized schedule RA-3-4-SDR considered user needs and other imagery (Meteosat ) Matched against technical constraints New schedule went operational on 6 May 2014 Ensures scanning of most of South America at least hourly at all times In addition, Group generates GEO- LEO mosaic for low-coverage areas Routine GOES-13 Rapid Scan GOES-13 Geographic location proposed by RA III/IV SDR Group
GOES 13 images to South America Goes-East No Routine Operation Images each hour Northern SAC MSG SAS NOAA POLAR ORBIT In cooperation with Argentina will be added to fill high latitude 14
NOAA Satellite Conference Action Items (2013) Action Response NOAA (8 Apr 2015) 6) Will GEONETCast be an operational system that users can base their operations on? GEONETCast Americas is complementary to NOAA s direct readout and online dissemination services. NOAA is working closely with regional partners to support the nine GEOSS Societal Benefit Areas and to address the requirements of the Coordination Group on Satellite Data requirements for RA III and RA IV. The internet connection, processing system, satellite uplinking system, and satellite transponder are all monitored 24 x 7 x 365. The operation of individual content channels, configuration settings within the accounts and incoming products are administered on an 8 x 5 or Monday through Friday basis and are therefore best effort. Availability of the broadcast is nearly 100%. 8) Can NOAA, in coordination with RA III, create a Satellite Application Partners (SAP) team to address the following applications: lightning, winds, sounding, cloud classification, precipitation estimation etc.? 10) Can NOAA, in coordination with RA III, create a Satellite Archive and Dissemination Partners (SADP) team to mirror data access and historical data dissemination for the users mainly interested in products? Increased coordination with RA III is possible and will need to be pursued virtually and possibly through visiting Scientist exchanges of subject matter experts. In some instances, the RA III and RA IV Satellite Data Requirements Coordination Group may be a vehicle for strengthened coordination.. The RA III and RA IV Satellite Data Requirements Coordination Group may be a vehicle for strengthened coordination. This group will be meeting at NSC 2015 and these items can be discussed. 16
NOAA Satellite Conference Action Items (2013) Action Response NOAA (8 Apr 2015) NOAA continues to support the regional GEONETCast Americas (GNCA) service and has made several enhancements to the broadcast in coordination with our partners. GNCA is part of the global GEONETCast system [ ] NOAA is working closely with regional partners to support the nine GEOSS Societal Benefit Areas and to address the requirements of the Coordination Group on Satellite Data requirements for RA III and RA IV. GNCA product requests are vetted by the GNCA Coordination Group [ ] 12) Can NOAA provide a better definition (use and planned use) of the GEONETCast system? NOAA and its partners completed two projects to add GOES East Full Disk imagery in three channels, in GEOTIFF format in 2014 and then to add GOES East North and South Sector imagery in three channels, in GEOTIFF format in February 2015. NOAA plans to replace the GOES East NOP imagery with an equivalent amount of GOES-R series imagery if GOES-R is placed at the GOE S East position. GNCA supports capacity building through assisting the efforts of countries to add receive stations and develop national networks like those in Brazil, El Salvador, Costa Rica, Colombia and planned in Mexico; collaboration with the WMO Virtual Laboratory for Training and Education in Satellite Meteorology (VLab) and promoting participation in the GEONETCast Americas Coordination Group. test footer 17

Points for Discussion 1. How to ensure that data distribution systems meet the regional satellite data requirements on an operational basis? 2. How to prepare the Region to receive and exploit data from the next satellite generation (GOES-R)? 3. How to ensure effective dialogue of Group with satellite operators at both technical and management levels? 4. How to ensure continued leadership and support to the Group?
