  1. Status Report on the Current and Future Satellite Systems of Japan Meteorological Agency Hironobu YOKOTA Satellite Program Division Observations Department Japan Meteorological Agency

  2. History of “Himawari” Overview - Planning of Japanese GEO satellite systems GMS (Geostationary Meteorological Satellite) (GOES-9) GMS-5 GMS GMS-2 GMS-3 GMS-4 (Himawari-5) (Himawari) (Himawari-2) (Himawari-3) (Himawari-4) Back-up operation of GMS-5 with GOES-9 by NOAA/NESDIS from May 22, 2003 to June 28, 2005 Sep 1989 Mar 1995 Aug 1981 Aug 1984 Jul 1977 MTSAT(Multi-functional Transport SATellite ) MTSAT-1R MTSAT-2 (Himawari-7) (Himawari-6) Himawari Himawari-8 Himawari-9 Feb 2005 Feb 2006 2014 2016

  3. Coordination Group for Meteorological Satellites - CGMS Observation/Direct Broadcast Configurations and landline distribution by MTSAT-1R/2 CURRENT GEO SATELLITES Observation by MTSAT-2 (145 deg E) Direct Broadcast via MTSAT-1R (140 deg E) Observed Imagery; • 24 full disk images • 24 northern hemisphere images • 8 southern hemisphere images for AMVs extraction MTSAT-1R (140 deg E) MTSAT-2 (145 deg E) Imagerraw data LRIT HRIT Landline distribution HRIT format data IR-1 to 4 and VIS SDUS MSC/JMA Image data for SATAID IR-1 to 4 and VIS JPEG image file IR-1,3,4 and VIS MDUS Internet JDDS Internet server (FTP) Processed into Imagery HRIT/LRIT

  4. Himawari-8/9 Schedule FUTURE GEO SATELLITES • JMA plans to launch Himawari-8 in 2014and begin its operation in 2015 • The launch of Himawari-9 for in-orbit standby is also scheduled in 2016 • Himawari-8/9 will be in operation around 140 degrees East covering the East Asia and the Western Pacific for 15 years

  5. FUTURE GEO SATELLITES Advanced Himawari Imager (AHI) instruments on the Himawari-8 is under manufacturing by ITT Exellis

  6. FUTURE GEO SATELLITES Specification of “Himawari-8/9” Imager(AHI) as of HIMAWARI-8/9 Full Disk Image every 10 minutes RGB Composited True Color Image X X X 1.3 μm for GOES-R X X X X Water Vapour X X SO2 X O3 X X Atmospheric Windows X X X CO2 as of MTSAT-1R/2 X: ABI

Region1 NE-JAPAN Region2 SW-JAPAN Region 3 Typhoon Region 4 Land mark Region 5 Land mark AHI Sectored Observations in 10 minutes FUTURE GEO SATELLITES Full disk Interval : 10 minutes (6 times per hour) 23 swath Region 1 JAPAN (North-East) Interval : 2.5 minutes (4 times in 10minutes) Dimension : EW x NS: 2000 x 1000 km 2 swath Region 2 JAPAN (South-West) Interval : 2.5 minutes (4 times in 10minutes) Dimension : EW x NS: 2000 x 1000 km 2 swath Region 3 Typhoon Interval : 2.5 minutes (4 times in 10minutes) Dimension : EW x NS: 1000 x 1000 km 2 swath Region 4 Land mark Interval : 0.5 minutes (20 times in 10minutes) Dimension : EW x NS: 1000 x 500 km 1 swath Region 5 Land mark Interval : 0.5 minutes (20 times in 10minutes)Dimension : EW x NS: 1000 x 500 km 1 swath

  8. (VIS, NIR) (IR) FUTURE GEO SATELLITES Estimated SRFs (Spectral Response Functions) of AHI is available in JMA/MSC Web Page https://mscweb.kishou.go.jp/himawari89/space_segment/spsg_ahi.html

  9. FUTURE GEO SATELLITES Disseminating Plan of Himawari-8/9 data (Draft ) Commercial Telecommunication Satellite (CTS) Himawari-8/9 • Disaster areas where landlines are down • Countries where landlines are not well-developed C-band (3 GHz)HRIT/LRIT compatible data Data CTS Operator USERS Internet Full data Users with developed Internet environment JMA jpeg imagery Users with limited Internet connection

  10. Himawari-8/9 Imagery Data Dissemination via Commercial Telecommunication Satellites FUTURE GEO SATELLITES Feasibility Study has just started in JMA # No budget commitment at present Feasibility study on data dissemination via commercial telecommunication satellites in early 2013 Parallel dissemination for users’ smooth transition from MTSAT to Himawari

  11. Data formats of imagery of the Himawari-8/9 ( Tentative plan) ( Tentative plan) FUTURE GEO SATELLITES
