Recently, Dr. M. De Mazière and Dr. Michel Van Roozendael, Senior scientists in Belgian Institute of Space Aeronomy (BIRA-IASB), were invited to visit Anhui Institute of Optics and Fine Mechanics (AIOFM). Both sides carried the academic exchange in the field of environmental gas observation. Prof. XIE Pinhua, vice Dean of AIOFM, extended her warm welcome to the arrival of the two scientists and held the seminar.
Dr. M. De Mazière gave a presentation entitled Greenhouse gas studies from ground and space in which she showed the details of the research progresses in the detection of greenhouse gases in atmosphere. From the ground, they used the detection platforms of Total Carbon Column Observing Network (TCCON) and Network for the Detection of Atmospheric Composition Change (NDACC) to measure the column-averaged dry air mole fraction of CO2, CH4, N2O, H2O and CO, and check the data from satellite with it. From the space, they made the nadir observations of greenhouse gases by such satellite missions as GOSAT, OCO-2 and IASI. In order to derive useful information about the carbon cycle and carbon fluxes, high resolution Fourier transform spectrum were used in the concentration detection of greenhouse gas. A new method for measuring in-situ vertical profiles of greenhouse gases is the Aircore system system is in trial.
Later, further bilateral cooperation was discussed.
