On April 24, China Meteorological Administration (CMA) released the Emergency Support Mechanism for International Users of FengYun Meteorological Satellites in Disaster Prevention and Mitigation (hereinafter referred to as Mechanism). When suffering from meteorological disasters such as typhoons, rainstorms, severe convections, forest and grassland fires, sandstorms, the countries along the “Belt and Road” may apply for initiating the Mechanism to get high-frequency cloud atlas and quantitative products from Fengyun satellites.

The countries along the “Belt and Road”are expected to apply for initiating this Mechanism through permanent delegates or designated contact persons with WMO. After the Mechanism is activated, CMA will manoeuvre on-duty Fengyun satellites to exercise regional observations every five or six minutes. Then the images and quantitative products will be delivered to applicants via various ways such as CMACast and satellite broadcasting.

The weather-related extremes have been increasing in number and intensity against the backdrop of global climate change, posing a great threat to life and property. In such case, weather satellites have become an indispensable tool to fight against natural disasters. As of now, China boasts nine Fengyun meteorological satellites which are on-orbit operation. These satellites serve as backup for each other in term of data acquisition and storage and operate as a whole. Fengyun family is not only an important member of global earth observation system, but also the on-duty satellites under the mechanism of the international charter on disaster reduction. Currently, the data and products from Fengyun satellites have covered more than 80 countries and regions, and domestic users amount to 2,500.

It is reported that China is capable of fully monitoring typhoons generated in West Pacific and are forecasted to make landfall on or affect China since the operation of FY-2 satellites in 1998.

Fengyun satellites will further give support to the building of space information corridor and disaster prevention and reduction system of “Belt and Road”. FY-4A, the next-generation geostationary meteorological satellites of China, will provide data and products for users from home and abroad after being put into official operation. (April 27)

The full text reads as follows:

Emergency Support Mechanism for International Users of FengYun Meteorological Satellites in Disaster Prevention and Mitigation

  Part I General Regulations

Article 1 The FengYun geostationary meteorological satellites provide intensive observations within coverage of the on-duty satellite. The FY-2 Satellite observes every 6 minutes, at a range of ±60°longitude of the subpoint and ±10°latitude at the center of the observation area. The FY-4 satellite observes up to every 5 minutes, with the observation range being set based on actual demands and observation frequency. The FengYun geostationary meteorological satellites provide nominal datasets and derived products. The list and description of intensive on-duty satellites and observations that they provide will be regularly updated on the portal of the National Satellite Meteorological Center (NSMC) of China Meteorological Administration (CMA).

Article 2 The international users of FengYun meteorological satellites refer to those authorized by the China Meteorological Administration within coverage of the intensive on-duty satellite.

Article 3 In the case that an international user of FengYun meteorological satellite is affected by meteorological disasters such as typhoons, rainstorms, severe convections, forest and grassland fires, sandstorms, it may apply for regional intensive observation by FengYun geostationary satellites.

Part II Application Procedure

Article 4 Application

1. In the case that an international user requires an intensive observation, an application generally shall be filed over 24 hours in advance, with the longest intensive observation not exceeding 48 hours.

2. The authorized international users log on to their accounts on the portal of NSMC/CMA to accurately fill in the starting and ending time and range of the intensive observation, and reasons and purpose of the application.

Article 5 Change of application

In the case that an international user extends or early terminates the intensive observation, it shall fill in an application for change through its authorized account on the portal of NSMC/CMA.

Article 6 Review of application

Once the application is received, NSMC/CMA determines whether the intensive observation is launched based on the operational status of the FengYun geostationary meteorological satellites, and gives feedbacks to the applying user.

Part III Data Access

Article 7 Launch of regional intensive observation

Once the application is reviewed, NSMC/CMA launches its FengYun Geostationary satellite for the intensive observation, with relevant data and products being generated.

Article 8 Dissemination of data and products

The data, images and quantitative products from the regional intensive observation by FengYun geostationary meteorological satellites are provided for the international users via CMACast, the Portal of NSMC/CMA, and satellite broadcasting.

Part IV Feedback

Article 9 Application summary

The international users shall provide timely feedbacks to NSMC/CMA on the utilization of data and products from the intensive observation.
