Himawari‐8/9 data distribution/dissemination plan

1

Japan Meteorological Agency (JMA)Hidehiko MURATA “Himawari”

is the name ofthis flower in Japanese

ET‐SUP‐8, WMO HQ, Geneva, 14‐17 April 2014

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.

JMA plans to launch Himawari‐8

in 2014

and begin its operation

in 2015.

The launch of Himawari‐9

for in‐orbit standby is scheduled in

2016.

Himawari‐8/9

will be in operation around 140 degrees East

covering the East Asia and Western Pacific regions for 15 years.

The tentative data set

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.)

Features

Notes

Basically one download per one nation.

Registration for account is required.

JMA’s websites

For general public use, JMA is

providing the current satellite imagery

on JMA’s website.

JMA will continue this service even after Himawari‐8 succeeds to JMA’s operational

satellite.

For meteorological services, JMA is

making the various types of cut‐out

imagery available on JMA’s website.
