覆盖我国的气象卫星系统及其应用

引言□□气象卫星自６０年代初问世以来，在此后的３０余年中得到了极大的发展。随着卫星和处理技术的不断进步，人类得以利用气象卫星从太空获取大量有关地球及其大气的物理和生态参数，使我们对地球的了解从深度到广度上都达到了前所未有的程度。我国是使用气象卫星资料较早的国家之一，早在１９６９年就已开始接收、处理和应用国外气象卫星的资料。同时，亦在积极地研制和发展我国自己的气象卫星系统。我国于１９８８年和１９９０年先后成功地发射了两颗自行研制的极轨气象卫星风云－１Ａ和１Ｂ（ＦＹ－１Ａ和１Ｂ），它们的后续星（ＦＹ…

国内外气象卫星发展(上)

1　引言□□自从1960年美国发射第1颗气象卫星以来,气象卫星有了长足的发展。卫星轨道从低轨(极地轨道)发展到高轨(地球静止轨道),发射卫星的国家或组织除美国、欧空局、俄罗斯和日本外还有印度和中国。与此同时,气象卫星资料的接收、处理、分发和存档管理,特别是应用也蓬勃地发展起来。60年代以来,中国天气预报的准确率有了相当大的改进,其主要原因有2个:1个是大型计算机和数值预报的采用;另1个是气象卫星观测资料的应用。气象卫星资料除了在天气预报中起重要作用外,还在环境监测特别是一些自然灾害的监测,例如林火、洪涝和雪灾等监测中起…     

气象卫星遥感海面温度的资料处理方法

气象卫星遥感海面温度的资料处理关键环节是云检测(筛选晴空区)和大气削弱订正。目前卫星气象中心的卫星海面温度处理业务系统中,针对美国的NOAA 卫星是利用国际上普遍使用的红外窗区多通道法。对于中国发射的风云一号(FY-1)气象卫星,由于星载辐射计只有一个红外窗区通道能用于大气削弱订正,为此专门开发了单通道海面温度处理方法。文章介绍了两种方法的基本原理、算法和处理结果举例,并对两种方法的特点作了简要评价。

Fengyun Satellites: Achievements and Future

Chinese meteorological satellite, Fengyun (FY) Satellite, has a polar-orbiting series and a geostationary series. Up to now, 5 polar-orbiting (FY-1A/B/C/D and FY-3A) and 5 geostationary (FY-2A/B/C/D/E) satellites were launched. FY data has been being intensively applied not only to meteorological monitoring and prediction but also to many other fields regarding ecology, environment, disaster, space weather and so and. The FY data sharing system, FengyunCast, is now one of the three components of global meteorological satellite information dissemination system, GEONETCast. The first satellite of the new generation polar-orbiting series, FY-3A, was launched on 27 May, 2008, demonstrating the FY polar-orbiting satellite and its application completed a great leap to realize three-dimensional observations and quantitative application. The first of the next generation geostationary series (FY-4) is planned to launch in 2014.

Update on Fengyun Meteorological Satellite Program and Development

China began to develop its meteorological satellite program since 1969. With 50-years' growing, there are 17 Fengyun (FY) meteorological satellites launched successfully. At present, seven of them are in orbit to provide the operational service, including three polar orbiting meteorological satellites and four geostationary meteorological satellites. Since last COSPAR report, no new Fengyun satellite has been launched. The information of the on-orbit FY-2 series, FY-3 series, and FY-4 series has been updated. FY-3D and FY-2H satellites accomplished the commission test and transitioned into operation in 2018. FY-2E satellite completed its service to decommission in 2019. The web-based users and Direct Broadcasting (DB) users keep growing worldwide to require the Fengyun satellite data and products. A new Mobile Application Service has been launched to Fengyun users based on the cloud technology in 2018. In this report, the international and regional co-operations to facilitate the Fengyun user community have been addressed especially. To strengthen the data service in the Belt and Road countries, the Emergency Support Mechanism of Fengyun satellite (FY_ESM) has been established since 2018. Meanwhile, a Recalibrating 30-years' archived Fengyun satellite data project has been founded since 2018. This project targets to generate the Fundamental Climate Data Record (FCDR) as a space agency response to the Global Climate Observation System (GCOS). At last, the future Fengyun program up to 2025 has been introduced as well.

FY-3 is the second generation polar-orbiting meteorological satellite of China. The first satellite named FY-3A of this series was launched on 27 May 2008. The first operational satellite named FY-3C of this series was launched on 23 September, 2013. The new generation satellites are to provide three-dimensional, quantitative, multi-spectral global remote sensing data under all weather conditions, which will greatly help the operational numerical weather prediction, global climate change research, climate diagnostics and prediction, and natural disaster monitoring. They will also provide help for many other fields such as agriculture, forestry, oceanography and hydrology. With the abovementioned capability, the FY-3 satellites can make valuable contributions to improving weather forecasts, global natural-disaster and environmental monitoring.

Recent Progress of Fengyun Meteorology Satellites

After nearly 50 years of development, Fengyun (FY) satellite ushered in its best moment. China has become one of the three countries or units in the world (China, USA, and EU) that maintain both polar orbit and geostationary orbit satellites operationally. Up to now, there are 17 Fengyun (FY) satellites that have been launched successfully since 1988. There are two FY polar orbital satellites and four FY geostationary orbit satellites operate in the space to provide a huge amount of the earth observation data to the user communities. The FY satellite data has been applied not only in the meteorological but also in agriculture, hydraulic engineering, environmental, education, scientific research and other fields. More recently, three meteorological satellites have been launched within the past two years. They are FY-4A on 11 December 2016, FY-3D on 15 November 2017 and FY-2H on 5 June 2018. This paper introduces the current status of FY meteorological satellites and data service. The updates of the latest three satellites have been addressed. The characteristics of their payloads on-boarding have been specified in details and the benefit fields have been anticipated separately.
