公共气象服务网站数据的及时发布

摘要

Focused on the web construction of a content management system, the acquisition, processing, and releasing of surface meteorological observation data for public weather service are introduced. The data layer is the key part of the system, in which the acquired information is processed in aspects of quality control and statistical analysis. The hourly data recoding and storing into the database are conducted while the sequentially updated statistical results for daily/ten-day/month/year reports are calculated. Through the time-sequence analysis and the 2D GIS graphic analysis, the processed information is visualized and can be inquired by public with different demands. In application, the system works efficiently with the data from 2566 meteorological stations in China and provides services for several public portals.%从公共气象服务网站中内容管理系统的建设出发,介绍了地面气象信息的采集、处理和及时面向网站发布的技术方法和实现方式.网站系统以数据层为核心,对操作层获取的气象信息进行质量控制和统计分析,在完成每小时数据记录入库的同时计算出以日、旬、月、年为时间尺度的记录和相应的气候值.库存的气象信息可以Web 方式被公众查询,并经时间序列分析软件和二维GIS图形分析软件处理,可直观表现不同时间尺度下气象要素的现状和历史对比.目前,该系统采用中国2566个自动地面气象观测站提供的数据,为中国天气网、四川气象网、成都公共气象服务网和四川农村信息网提供查询服务,运行良好.
