河南省CMACAST数据处理系统研究

“9210”工程建成后，河南省气象信息中心通过DVBS卫星数据接收系统接收各种气象原始资料，由MICAPS处理程序处理为各类气象资料供气象台预报员调阅使用。伴随着现代生活水平的提高以及气象事业的迅速发展，公众对气象预报产品的时效和精细化都提出了更高的要求。因此气象台预报员对预报所需要的资料也提出了更高的要求。河南省信息中心将通过DVBS卫星数据系统接收到的原始资料进行处理已经不能满足预报员的需求。河南省气象信息中心通过CMACAST卫星数据广播系统接收各种气象资料，每天接收到的资料有三十八类，多达100多G。海量的气象资料需要高性能的处理系统将其处理为气象产品，供预报员调阅。CMACAST数据处理系统将接收到的气象资料推入队列中依次进行处理为MICAPS资料，供气象台预报员调阅。CMACAST数据处理系统由5个功能模块组成，分别为服务器环境配置模块，数据处理模块，数据监控模块，数据备份模块，数据还原模块。这些模块为维护人员监控各类资料的处理情况和维护CMACAST数据处理系统提供了重要的技术支持，降低了维护的难度和复杂度。采用XML作为数据接口文件，使CMA-CAST数据处理系统具有较强的可扩展性。目前CMACAST数据处理系统已经成为为气象台提供资料服务的重要平台。

The Study of HeNan Province CMACAST Data Processing System

After the completion of the“9210”project,Henan Provincial Meteorological Information Center receives all kinds of meteorological data by DVBS satellite data broadcasting system and processes into MICAPS data for forecaster accessing in Henan meteorological bureau.Witj modern living standards improving and the rapid development of the meteorological cause,the public has put forward higher requirements on ageing and fine meteorological forecast products.Therefore meteorological forecasters put forward higher requirements on needing forecast information..Henan Provincial Meteorological Information Center processing data reveiving through the DVBS satellite data broadcasting system has been unable to meet the needs of the forecasters.Henan Provincial Meteorological Information Center receives various kinds of meteorological data through the CMACAST satellite data broadcasting system, receiving daily data of thirty-eight categories, more than 100 G. Massive meteorological data needs high per-formance system processing into weather products accesed for forecasters.CMACAST data processing system is composed of 5 modules and respectively is the server configuration module, data processing module, data monitoring module, data backup mod-ule and data reduction module.These models provide an important technical support for monitor and maintain the CMACAST data processing system and reduce the maintenance difficulty and complexity.XML is data interface of CMACAST data process-ing system,and makes the system having highly scalability. CMACAST data processing system is an improtant supproting technol-ogy of data service for Henan meteorological bureau.
