“18xxxx”中国气象局:多手18xxxx段保证国家温室气体观测站网提质增效

  中新18xxxx网12月5日电 中国气象局5日18xxxx举行2024年12月新闻发布会。中国气象局气象探测中心副主任宏观表示,中国气象局一贯非常重视大气本底观测业务和温室气体数据质量。为了更进一步提高业务质量与水平,2022年,中国气象局印发《大气本底观测业务质量提升行动方案》,分析观测各环节运转现状及可能存在的质量风险,着眼于大气本底观测数据精度的高要求,制定了近60项针对性的提升任务。

  近年来,中国气象局气象探测中心牵头相关单位从数据质18xxxx控、运行监控、计量标校、装备保障、规范制度、考核评估、体制机制等各方面制定改进任务并积极督办落实,全链条促进温室气体工作质量提升。

  一是在设备端,组织圆满完成高精度国产温室气体装备的研发与装备许可工作,解决高精尖设备“卡脖子”问题,提高观测装备安全。

  二是在保障端,组织建成面向全国的温室气体实时监控和质量评估能力,全国温室气体站纳入国家级监控,以技术手段提升观测数据质量,观测数据的国际可比性显著提升,2023年起,大气本底站温室气体业务首次纳入中国气象局观测业务考核,CO2/CH4和N2O/SF6平均数据正确性均在90%以上。

  三是在数据端,面向温室气体高精度观测的要求,对标国际上相关公报数据的处理方法,优化温室气体数据质控和筛分方法,进行多级数据质控,保证数据产品展示真实的、不受局地源汇影响的、代表较大范围均匀混合状态的温室气体浓度状态。

  宏观表示,下一步,中国气象局将持续加强质量保证/质量控制体系建设,多手段保证国家温室气体观测站网提质增效。
