我国首个全球大气成分变化探测网络标准站已在合肥运行。据中国科学院合肥物质科学研究院官方消息，2023年11月，由中国科学院环境光学与技术重点实验室（安光所）建设的高分辨率傅里叶变换光谱（FTS）观测平台（合肥站）通过了全球大气成分变化探测网络（NDACC）的数据质量认证，被接收为中国首个NDACC-IRWG（IRWG指红外工作组）标准站。
该观测站部署在安徽省合肥市科学岛的大气环境光学综合观测场内，包括高分辨率FTIR光谱观测系统、太阳追踪仪和气象站等。FTS团队的学术带头人、中国科学院环境光学与技术重点实验室副主任刘诚教授带领团队，成功实现了多种大气痕量气体数据的精准观测，包括臭氧（O3）、一氧化碳（CO）、二氧化氮（NO2）等污染气体，以及二氧化碳（CO2）、甲烷（CH4）等温室气体。
全球大气成分变化探测网络（NDACC）由全球70多个地基遥感观测站点组成，旨在建立全球长期观测大气成分变化和趋势数据库。其数据已受到国际科学研究机构的广泛认可，得到联合国环境规划署（UNEP）、国际气象和大气科学协会国际臭氧委员会的大力支持。
合肥站加入NDACC后，有望为我国减污降碳协同控制战略提供具有国际公信力的数据。此次成果标志着我国在大气成分变化探测领域取得了重要突破，有助于进一步研究大气成分变化对气候变化和空气质量的影响。
Title: China’s first global atmospheric composition change detection network standard station operates in Hefei
Keywords: Atmospheric composition, detection network, standard station
News content:
China’s first global atmospheric composition change detection network standard station has been put into operation in Hefei. According to the official message of the Hefei Institute of Physical Science, Chinese Academy of Sciences, in November 2023, the high-resolution Fourier transform spectroscopy (FTS) observation platform (Hefei Station) built by the Key Laboratory of Environmental Optics and Technology (An optical station) of the Chinese Academy of Sciences passed the data quality certification of the Global Atmospheric Composition Change Detection Network (NDACC) and was accepted as China’s first NDACC-IRWG (IRWG refers to infrared working group) standard station.
The observation station is deployed in the Comprehensive Atmospheric Environmental Optical Observation Field on Science Island, Anhui Province, including high-resolution FTIR spectroscopy observation system, solar tracking instrument, and meteorological station. Academician Liu Cheng, the academic leader of the FTS team and the deputy director of the Key Laboratory of Environmental Optics and Technology, led the team to successfully achieve precise observation of various atmospheric trace gas data, including pollutants such as ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), and greenhouse gases such as carbon dioxide (CO2) and methane (CH4).
The Global Atmospheric Composition Change Detection Network (NDACC) consists of more than 70 ground-based remote sensing observation stations worldwide and aims to establish a long-term global observation database for atmospheric composition changes and trends. Its data has been widely recognized by international scientific research institutions and has received strong support from the United Nations Environment Programme (UNEP), the International Meteorological and Atmospheric Science Association’s International Ozone Commission.
After joining NDACC, Hefei Station is expected to provide internationally credible data for China’s pollution and carbon reduction coordination strategy. This achievement marks an important breakthrough in the field of atmospheric composition change detection in China, contributing to further research on the impact of atmospheric composition changes on climate and air quality.
