Full Disc Scan: the GIIRS is able to scan the full earth disc within about 2 hours, and a total of about 1530 views are needed. The full disc is revisited every 6 hours, and Level 1 data can be provided.

The GIIRS radiance measurements in LWIR and MWIR at four samples are shown. Sample A indicates the relatively warm and humid clear atmosphere. Sample B and D represent the dry and cold atmosphere at high latitudes. Sample C shows the typical cloudy sky.

On-site Support and Training for International Users

Plan： On-site support and training on FY-4 application platform to 5 selected countries of Asia and Oceania every year.

summary CMA has carried out lots of work on FY-4 readiness and make some progress： • Upgraded the application software and data service system.

Proposed a new data transmission solution (plan) using public cloud service.

• Developed 28 FY-4 baseline products and produced them in real time using FY-2 and H8 as proxy data.

• Set up more than 30 demonstration projects and gained several outcomes.

• Organized a series of training activities for domestic and international users.
