Development of the Protocol for the Request of Himawari-8/9

Rapid-scan observation

Introduction

2

• AHI (Advanced Himawari Imager) on Himawari-8/9 has the ability of various scans during 10 minutes Full Disk observation.

• AHI can flexibly change the scan range of “Target Area (Region 3)” for observation of phenomena such as typhoons and active volcanoes.

• Currently, Himawari-8/9 rapid scan target area observation is mainly focused on – tropical cyclones in the RSMC Tokyo - Typhoon Center's area of responsibility – volcanic eruptions for the Tokyo Volcanic Ash Advisory Center (VAAC Tokyo)

Introduction

• Jakarta Declaration (October 2015) – The Joint RA-II/RA-V Workshop on WIGOS for

Disaster Risk Reduction

– one of its goals is “developing a protocol for NMHSs of the countries in the region to request event-driven rapid scan imagery”

• RA II WIGOS Project on “Develop Support for NMHSs in satellite Data, Products and Training”

– To develop a protocol for NMHSs of the countries in the Region to request event-driven rapid Scan imagery

– To assist NMHSs to utilize rapid scan data in support of DRR in response to their requests

observation area of Himawari-8

Feasibility study on event-driven Rapid Scan (JMA & AuBoM)

• Based on the Jakarta Declaration, JMA and AuBoM conducted a joint feasibility study toward the development of a protocol for the request of Himawari-8 Rapid Scan observation between February and March 2016.

• JMA collaborates with AuBoM to create the cyclone tracking system by “Target Area” observation during high season for cyclone (Southern Hemisphere) whereas low season for typhoon (Northern Hemisphere).

Method (feasibility study)

Himawari-8

JMA

• AuBoM creates the reservation file which specifies the duration and coordinates of observation. – AuBoM uploads the file on the dedicated web page. – JMA constantly surveils this web page.

• When AuBoM renews the reservation file, JMA “wget”s the file from the web page and makes a new command of “Target Area” specified (or defined ) in the file.

– JMA checks format, duration and coordinate of the reservation file (automatically). – In case of conflict between JMA’s observation and AuBoM’s one, the schedule coordinate system in

JMA adjusts each reservation based on pre-defined priority. ( e.g. set higher priority to typhoon observation than that of cyclone)

• The test observation was operated six days. • There was no cyclone within the area of responsibility of AuBoM. • The test itself were conducted and the observation was successfully

operated as AuBoM had expected.

Result (feasibility study)

• Target region of this protocol is RA II and RA V • Request is for “Region 3” observation of Himawari-8/9

– Every 2.5minutes observation • Basically, National Security or other national priorities or

interest of Japan is first priority – Tropical Cyclones in area of RSMC Tokyo – Volcano eruptions in area of Tokyo VAAC – Etc...

• AuBoM manages the request from NMHSs in southern Hemisphere – RA V countries outside the responsibility area of RSMC Tokyo and

Tokyo VAAC – AuBoM selects the first priority request in the region, and inform

to JMA

Draft Protocol (1/3)

• Tropical cyclones and volcano eruptions have priority over other event

• Request will be submitted via email according to the format designated by JMA – “Start time”, “end time”, “center position” should be included

• JMA will define the priorities among the requests, change the setting of Himawari-8/9, and start the observation – JMA may need some time to decide whether it should be observed

and/or which request should be selected. • Observation duration will be 48 hours at a maximum. (re-request

is acceptable) • Tropical Cyclone outside the responsibility area of RSMC Tokyo

– JMA doesn’t have the information of the center location – NMHSs should prepare the system which inform JMA about the center

location

Draft Protocol (2/3)

• Observation data is available on, – HimawariCloud (internet data distribution system) – MSC web (jpeg image only)

• Feedback – NMHSs should send feedback to JMA and AuBoM

about the effectiveness of rapid scan, comparing with simultaneous 10 minutes full disk observation.

Draft Protocol (3/3)

Technical Implementation

• JMA, AuBoM and each NMHS to determine authorized contact points

• JMA to determine the request form of email. • AuBoM to develop the automatic system to inform the center

location of a tropical cyclone to JMA • AuBoM to make a coordination for the member countries in

RA V outside the responsibility area of RSMC Tokyo and Tokyo VAAC

• This protocol is under construction • JMA will report the further progress of

development at – CGMS-45 (June) – AOMSUC-8 and 5th WIGOS project coordination

group meeting (October)

• JMA supposes that this protocol will be activated after the AOMSUC-8
