AIOFM, HFIPS, announced on November 1st that its high-resolution Fourier Transform Spectroscopy (FTS) observation platform, located on Science Island in Hefei, has become the first NDACC-IRWG (Infrared Working Group) standard station in China. The announcement was made after the Hefei station successfully passed the data quality certification of the Network for the Detection of Atmospheric Composition Change (NDACC).

The FTS platform includes a high-resolution FTIR spectrometer, sun tracker, and meteorological station, enabling the detection of key atmospheric constituents' column total amounts and vertical profiles.

In the past eight years, scientists successfully conducted observations of various trace gases in the atmosphere, including pollutants and greenhouse gases. These observations have significant implications for understanding atmospheric composition changes and trends.

"This will help us to better understand atmospheric composition changes and their impacts on climate and air quality," said Prof. LIU Cheng, who led the team.

NDACC is a global network comprising more than 70 ground-based remote sensing observation sites worldwide. Since its establishment in 1991, NDACC has gained international recognition for its valuable contributions to research on the impacts of different gas components on the troposphere and stratosphere, as well as the links and feedbacks between changes in atmospheric composition, climate, and air quality.
