用应用需求数据库评估卫星观测能力

Evaluation of Satellite Observing Capacity Using Meteorological Satellite Application Database

卫星应用需求分析是气象卫星规划和研制十分关键的第一步。为了搞好21世纪的全球气象卫星发展规划,WMO和CEOS从1996年开始征集全球对地观测卫星的应用需求和建立卫星需求数据库,创立了国际通行的RRR程序方法,建立了全球对地观测卫星应用需求数据库。文章介绍了WMO/CEOS卫星应用需求数据库的RRR程序方法和数据库的部分内容,着重介绍和评述了建立卫星应用需求数据库以及基于卫星需求数据库进行卫星观测能力定量评估的方法,为中国气象卫星应用需求数据库的建设创造有利条件。

The analysis of satellite user requirements is the first and critical step to plan and manufacture meteorological satellites. To outline the frame of global meteorological satellites in the 21st century, WMO and CEOS began to collect user requirement information and establish global user databases for earth observing satellites from 1996, and devised the Rolling Requirements Review （RRR） process methods. The RRR process method and parts of the WMO/CEOS user database are introduced. The emphasis is put on the presentation and review of the establishing of satellite user requirements and its application in the quantitative evaluation of satellite observing capacity, to found a base for establishing the Chinese meteorological satellite user requirement database.
