Himawari 8/9 data distribution/dissemination plan

Transcription

1 Himawari 8/9 data distribution/dissemination plan Japan Meteorological Agency (JMA) Hidehiko MURATA Himawari is the name of this flower in Japanese ET SUP 8, WMO HQ, Geneva, April

2 Outline The Japan Meteorological Agency (JMA) plans to start the operation of next generation Himawari 8 and 9 satellites in 2015 and 2017, respectively, as a replacement for current MTSAT 2 (Himawari 7). Himawari 8/9 will not carry equipment for direct dissemination of imagery. instead, all imagery will be distributed via an Internet cloud service. JMA also plans to start the HimawariCast service, by which primary sets of imagery via a communication satellite using DVB S2. 2

3 Overview of JMA s satellites GMS (Geostationary Meteorological Satellite) GMS (Himawari) Jul 1977 GMS 2 (Himawari 2) Aug 1981 GMS 3 (Himawari 3) Aug 1984 GMS 4 (Himawari 4) Sep 1989 GMS 5 (Himawari 5) CNASDA CNASDA CNASDA CNASDA CNASDA Mar 1995 (GOES 9) Back up operation of GMS 5 with GOES 9 by NOAA/NESDIS from May 22, 2003 to June 28, 2005 MTSAT (Multi functional Transport SATellite ) MTSAT 1R (Himawari 6) MTSAT 2 (Himawari 7) Satellite Observation period GMS GMS Himawari 8 Himawari Himawari 9 GMS GMS Feb 2005 CSS/L CMELCO Feb GMS GOES MTSAT-1R MTSAT Himawari Himawari

4 Transition of Satellites Manufacturing Launch Launch JMA plans to launch Himawari 8 in 2014 and begin its operation in The launch of Himawari 9 for in orbit standby is scheduled in Himawari 8/9 will be in operation around 140 degrees East covering the East Asia and Western Pacific regions for 15 years. 4

8 Format Observation Area Note Himawari Standard Data (HSD) PNG Full Disk Target Area Full Disk Target Area Internet Cloud Service Full Disk: Every 10 minutes Target Area: Every 2.5 minutes 16 bands The finest spatial resolution data The tentative data set True color images (composite image of 3 visible bands) Full Disk: Every 10 minutes Target Area: Every 2.5 minutes Same spatial resolution as Himawari Standard Data NetCDF Target Area Every 2.5 minutes 16 bands Same spatial resolution as Himawari Standard Data Features Each NMHS will be able to access the cloud, and get the data using a HTTP 1.1 client, such as a Web browser and Wget. Each NMHS will be able to select the necessary files for its operation. (HSD will be separately created for each band, and divided into 10 segments.) Notes Basically one download per one nation. Registration for account is required. 25 Mbps of the Internet access speed is required to download all HSD. 8

9 Data type Format Note HimawariCast Service The tentative data set Himawari 8/9 imagery (Full Disk) Numerical Weather Prediction Products (GPV) In situ Observations (Surface stations, ships, radiosondes) ASCAT Ocean Surface Wind (EUMETSAT) HRIT files LRIT files Compatible format with the current MTSAT series HRIT and LRIT services Every 10 minutes HRIT: 5 bands, LRIT: 3 bands Coarser spatial resolution than Himawari Standard Data SATAID format Products of JMA s Global Model (GSM) Every 6 hours SATAID format Collected observation data from the East Asia and Western Pacific regions SATAID format Originally provided by EUMETSAT OSI SAF, and converted into SATAID format by JMA Features With SATAID application, users will be able to superimpose various data and products on satellite imagery. (Please see the next slide.) Notes Receiving and processing system is required. 9

11 For general public use, JMA is providing the current satellite imagery on JMA s website. JMA s websites For meteorological services, JMA is making the various types of cut out imagery available on JMA s website. JMA will continue this service even after Himawari 8 succeeds to JMA s operational 11 satellite.
