海岛温室气体自动观测系统的设计与实现

Design and Implementation of Automatic GHGs Monitoring System for Sea Island

为获得中国近海大气温室气体浓度的高精度长时间序列连续观测数据,文章基于离轴积分腔输出光谱(OA-ICOS)原理的激光温室气体分析仪(GGA),结合多重过滤、冷凝除水、自动校准、数据传输、异常值筛分、数据可视化等多方面理论知识,设计了一套海岛基温室气体自动观测系统,并先后成功应用于西沙永兴岛、宁德北礵岛、舟山嵊山岛和南沙永暑岛,通过自主开发的数据传输系统和数据分析系统,系统可实现海岛大气温室气体的高频率、高精度连续观测,并具备自动校准、实时传输、数据筛分以及数据可视化功能,有望推动实现我国海岛基温室气体的高质量业务化观测。

In order to obtain the continuous long-term high-precision data of atmospheric greenhouse gases in sea island, based on the laser greenhouse gas analyzer(GGA, Greenhouse Gas Analyzer of Los Gatos Research, take advantage of OA-ICOS), combined with multiple filtering, condensation dewater, automatic calibration, data transmission, data filtering and data visualization, the authors designed the automatic GHGs monitoring system for sea island. The system has been successfully applied in Yongxing island, Beishuang island,Shengshan island and Yongshu island. Besides, the system of data transmission and data analysis were developed independently in order to continuously observe the state of GHGs in the island with high frequency and accuracy. The system has the multi-functions about automatic calibration, real-time data transmission, data screening as well as data visualization, which can promote the realization of the high-quality operational observation of the island-based GHGs in China.
