Satellite remote sensing is currently the best monitoring means to obtain global carbon source and sink data. The United States, Japan, China other countries are vigorously developing spaceborne detection technology. However, important factors that restrict application of greenhouse gas satellite technology include limited accuracy data products. How improve retrieval level payloads a problem n...
Analysis of Index Gases of Coal Spontaneous Combustion Using Fourier Transform Infrared Spectrometer
In this study, magnetite (Fe3O4) nanoparticles were synthesized by chemical co-precipitation from the solution containing iron salts in alkaline medium under N2 gas and room temperature. Magnetite nanoparticles were characterized by X- ray diffraction (XRD), Fourier transform infrared spectrometer (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermal gravim...
The DESIRS beamline of the SOLEIL synchrotron facility, equipped with a vacuum ultraviolet Fourier-Transform spectrometer has been used to measure Q(N ′′) (N−N ′′ = 0) absorption transitions of the D2 molecule. Some 212Q-lines were assigned and their transition frequencies determined up to excitation energies of 137000 cm−1 above the
